Method Detail

addNode

Node addNode(java.lang.String relPath)
             throws ItemExistsException,
                    PathNotFoundException,
                    VersionException,
                    ConstraintViolationException,
                    LockException,
                    RepositoryException

Creates a new node at relPath. The new node will only be persisted on save() if it meets the constraint criteria of the parent node's node type.

In order to save a newly added node, save must be called either on the Session, or on the new node's parent or higher-order ancestor (grandparent, etc.). An attempt to call save only on the newly added node will throw a RepositoryException.

In the context of this method the relPath provided must not have an index on its final element. If it does then a RepositoryException is thrown.

Strictly speaking, the parameter is actually a relative path to the parent node of the node to be added, appended with the name desired for the new node (if the a node is being added directly below this node then only the name need be specified). It does not specify a position within the child node ordering. If ordering is supported by the node type of the parent node then the new node is appended to the end of the child node list.

Since this signature does not allow explicit node type assignment, the new node's primary node type will be determined (either immediately or on save, depending on the implementation) by the child node definitions in the node types of its parent.

An ItemExistsException will be thrown either immediately (by this method), or on save, if an item at the specified path already exists and same-name siblings are not allowed. Implementations may differ on when this validation is performed.

A PathNotFoundException will be thrown either immediately, or on save, if the specified path implies intermediary nodes that do not exist. Implementations may differ on when this validation is performed.

A ConstraintViolationException will be thrown either immediately or on save if adding the node would violate a node type or implementation-specific constraint or if an attempt is made to add a node as the child of a property. Implementations may differ on when this validation is performed.

A VersionException will be thrown either immediately or on save, if the node to which the new child is being added is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in. Implementations may differ on when this validation is performed.

A LockException will be thrown either immediately (by this method), or on save, if a lock prevents the addition of the node. Implementations may differ on when this validation is performed.

Parameters:: relPath - The path of the new node to be created.
Returns:: The node that was added.
Throws:: ItemExistsException - if an item at the specified path already exists, same-name siblings are not allowed and this implementation performs this validation immediately instead of waiting until save.; PathNotFoundException - if the specified path implies intermediary Nodes that do not exist or the last element of relPath has an index, and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - if a node type or implementation-specific constraint is violated or if an attempt is made to add a node as the child of a property and this implementation performs this validation immediately instead of waiting until save.; VersionException - if the node to which the new child is being added is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save.; LockException - if a lock prevents the addition of the node and this implementation performs this validation immediately instead of waiting until save.; RepositoryException - If the last element of relPath has an index or if another error occurs.

addNode

Node addNode(java.lang.String relPath,
             java.lang.String primaryNodeTypeName)
             throws ItemExistsException,
                    PathNotFoundException,
                    NoSuchNodeTypeException,
                    LockException,
                    VersionException,
                    ConstraintViolationException,
                    RepositoryException

Creates a new node at relPath of the specified node type. The same as addNode(String relPath) except that the primary node type of the new node is explictly specified.

A NoSuchNodeTypeException will be thrown either immediately or on save, if the specified node type is not recognized. Implementations may differ on when this validation is performed.

A LockException will be thrown either immediately (by this method), or on save, if a lock prevents the addition of the node. Implementations may differ on when this validation is performed.

Parameters:: relPath - the path of the new node to be created.; primaryNodeTypeName - The name of the primary node type of the new node.
Returns:: the node that was added.
Throws:: ItemExistsException - if an item at the specified path already exists, same-name siblings are not allowed and this implementation performs this validation immediately instead of waiting until save.; PathNotFoundException - if the specified path implies intermediary Nodes that do not exist or the last element of relPath has an index, and this implementation performs this validation immediately instead of waiting until save.; NoSuchNodeTypeException - if the specified node type is not recognized and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - if a node type or implementation-specific constraint is violated or if an attempt is made to add a node as the child of a property and this implementation performs this validation immediately instead of waiting until save.; VersionException - if the node to which the new child is being added is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save.; LockException - if a lock prevents the addition of the node and this implementation performs this validation immediately instead of waiting until save.; RepositoryException - if the last element of relPath has an index or if another error occurs.

orderBefore

void orderBefore(java.lang.String srcChildRelPath,
                 java.lang.String destChildRelPath)
                 throws UnsupportedRepositoryOperationException,
                        VersionException,
                        ConstraintViolationException,
                        ItemNotFoundException,
                        LockException,
                        RepositoryException

If this node supports child node ordering, this method inserts the child node at srcChildRelPath before its sibling, the child node at destChildRelPath, in the child node list.

To place the node srcChildRelPath at the end of the list, a destChildRelPath of null is used.

Note that (apart from the case where destChildRelPath is null) both of these arguments must be relative paths of depth one, in other words they are the names of the child nodes, possibly suffixed with an index.

If srcChildRelPath and destChildRelPath are the same, then no change is made.

Changes to ordering of child nodes are persisted on save of the parent node. But, if this node does not support child node ordering, then a UnsupportedRepositoryOperationException thrown.

If srcChildRelPath is not the relative path to a child node of this node then an ItemNotFoundException is thrown.

If destChildRelPath is neither the relative path to a child node of this node nor null, then an ItemNotFoundException is also thrown.

A ConstraintViolationException will be thrown either immediately or on save if this operation would violate a node type or implementation-specific constraint. Implementations may differ on when this validation is performed.

A VersionException will be thrown either immediately or on save, if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in. Implementations may differ on when this validation is performed.

A LockException will be thrown either immediately (by this method), or on save, if a lock prevents the re-ordering. Implementations may differ on when this validation is performed.

Parameters:: srcChildRelPath - the relative path to the child node (that is, name plus possible index) to be moved in the ordering; destChildRelPath - the the relative path to the child node (that is, name plus possible index) before which the node srcChildRelPath will be placed.
Throws:: UnsupportedRepositoryOperationException - if ordering is not supported.; ConstraintViolationException - if an implementation-specific ordering restriction is violated and this implementation performs this validation immediately instead of waiting until save.; ItemNotFoundException - if either parameter is not the relative path of a child node of this node.; VersionException - if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save..; LockException - if a lock prevents the re-ordering and this implementation performs this validation immediately instead of waiting until save..; RepositoryException - if another error occurs.

setProperty

Property setProperty(java.lang.String name,
                     Value value)
                     throws ValueFormatException,
                            VersionException,
                            LockException,
                            ConstraintViolationException,
                            RepositoryException

Sets the specified (single-value) property of this node to the specified value. If the property does not yet exist, it is created. The property type of the property will be that specified by the node type of this node.

If the property type of the supplied Value object is different from that required, then a best-effort conversion is attempted. If the conversion fails, a ValueFormatException is thrown. If another error occurs, a RepositoryException is thrown.

If the node type of this node does not indicate a specific property type, then the property type of the supplied Value object is used and if the property already exists it assumes both the new value and new property type.

If the property is multi-valued, a ValueFormatException is thrown.

Passing a null as the second parameter removes the property. It is equivalent to calling remove on the Property object itself. For example, N.setProperty("P", (Value)null) would remove property called "P" of the node in N.

To persist the addition, removal or change of a property to the workspace, save must be called on the session, this node, or a higher-order ancestor of the property.

A ConstraintViolationException will be thrown either immediately or on save if the change would violate a node type or implementation-specific constraint. Implementations may differ on when this validation is performed.

A VersionException will be thrown either immediately or on save if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in. Implementations may differ on when this validation is performed.

A LockException will be thrown either immediately or on save if a lock prevents the setting of the property. Implementations may differ on when this validation is performed.

Parameters:: name - The name of a property of this node; value - The value to be assigned
Returns:: The updated Property object
Throws:: ValueFormatException - if value cannot be converted to the type of the specified property or if the property already exists and is multi-valued.; VersionException - if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save.; LockException - if a lock prevents the setting of the property and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - if the change would violate a node-type or other constraint and this implementation performs this validation immediately instead of waiting until save.; RepositoryException - if another error occurs.

setProperty

Property setProperty(java.lang.String name,
                     Value value,
                     int type)
                     throws ValueFormatException,
                            VersionException,
                            LockException,
                            ConstraintViolationException,
                            RepositoryException

Sets the specified (single-value) property to the specified value. If the property does not yet exist, it is created.

The type of the new property is determined by the type parameter specified.

If the property type of the supplied Value object is different from that required, then a best-effort conversion is attempted. If the conversion fails, a ValueFormatException is thrown.

If the property is not single-valued then a ValueFormatException is also thrown.

If the property already exists it assumes both the new value and the new property type.

Passing a null as the second parameter removes the property. It is equivalent to calling remove on the Property object itself. For example, N.setProperty("P", (Value)null, type) would remove property called "P" of the node in N.

To persist the addition or removal of a property, save must be called on the Session, this Node, or an ancestor of this Node.

To persist a change in the value of a property or in the type of a property (assuming the change is permitted by the applicable property definition) a save on the Property object itself is sufficent, though a save on the Session, this Node or an ancestor of this Node will also work.

A LockException will be thrown either immediately or on save if a lock prevents the setting of the property. Implementations may differ on when this validation is performed.

Parameters:: name - the name of the property to be set.; value - a Value object.; type - the type of the property.
Returns:: the Property object set, or null if this method was used to remove a property (by setting its value to null).
Throws:: ValueFormatException - if value cannot be converted to the specified type or if the property already exists and is multi-valued.; VersionException - if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save.; LockException - if a lock prevents the setting of the property and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - if the change would violate a node-type or other constraint and this implementation performs this validation immediately instead of waiting until save.; RepositoryException - if another error occurs.

setProperty

Property setProperty(java.lang.String name,
                     Value[] values)
                     throws ValueFormatException,
                            VersionException,
                            LockException,
                            ConstraintViolationException,
                            RepositoryException

Sets the specified (multi-value) property to the specified array of values. If the property does not yet exist, it is created. Same as setProperty(String name, Value value) except that an array of Value objects is assigned instead of a single Value.

The property type of the property will be that specified by the node type of this node. If the property type of the supplied Value objects is different from that required, then a best-effort conversion is attempted. If the conversion fails, a ValueFormatException is thrown.

All Value objects in the array must be of the same type, otherwise a ValueFormatException is thrown. If the property is not multi-valued then a ValueFormatException is also thrown. If another error occurs, a RepositoryException is thrown.

If the node type of this node does not indicate a specific property type, then the property type of the supplied Value objects is used and if the property already exists it assumes both the new values and the new property type.

Passing a null as the second parameter removes the property. It is equivalent to calling remove on the Property object itself. For example, N.setProperty("P", (Value[])null) would remove property called "P" of the node in N.

Note that this is different from passing an array that contains null elements. In such a case, the array is compacted by removing the nulls. The resulting set of values never contains nulls. However, the set may be empty: N.setProperty("P", new Value[]{null}) would set the property to the empty set of values.

To persist the addition, removal or change of a property to the workspace, save must be called on the session, this node, or a higher-order ancestor of the property.

A LockException will be thrown either immediately or on save if a lock prevents the setting of the property. Implementations may differ on when this validation is performed.

Parameters:: name - the name of the property to be set.; values - an array of Value objects.
Returns:: the updated Property object.
Throws:: ValueFormatException - if value cannot be converted to the type of the specified property or if the property already exists and is not multi-valued.; VersionException - if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save.; LockException - if a lock prevents the setting of the property and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - if the change would violate a node-type or other constraint and this implementation performs this validation immediately instead of waiting until save.; RepositoryException - if another error occurs.

                            LockException,
                            ConstraintViolationException,
                            RepositoryException

Sets the specified (multi-value) property to the specified array of values. If the property does not yet exist, it is created. The type of the property is determined by the type parameter specified.

If the property type of the supplied Value objects is different from that specified, then a best-effort conversion is attempted. If the conversion fails, a ValueFormatException is thrown.

If the property already exists it assumes both the new values and the new property type.

Passing a null as the second parameter removes the property. It is equivalent to calling remove on the Property object itself. For example, N.setProperty("P", (Value[])null, type) would remove property called "P" of the node in N.

                            ConstraintViolationException,
                            RepositoryException

Sets the specified property to the specified value. If the property does not yet exist, it is created. The property type of the property being set is determined by the node type of this node (the one on which this method is being called). If this is something other than PropertyType.STRING, a best-effort conversion is attempted. If the conversion fails, a ValueFormatException is thrown. If the property is multi-valued, a ValueFormatException is also thrown. If another error occurs, a RepositoryException is thrown.

If the node type of this node does not specify a particular property type for the property being set then PropertyType.STRING is used and, if the property already exists, it assumes both the new value and type PropertyType.STRING.

Passing a null as the second parameter removes the property. It is equivalent to calling remove on the Property object itself. For example, N.setProperty("P", (String)null) would remove property called "P" of the node in N.

To persist the addition, removal or change of a property save must be called.

A LockException will be thrown either immediately or on save if a lock prevents the setting of the property. Implementations may differ on when this validation is performed.

Parameters:: name - The name of a property of this node; value - The value to assigned
Returns:: The updated Property object
Throws:: ValueFormatException - if value cannot be converted to the type of the specified property or if the property already exists and is multi-valued.; VersionException - if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save.; LockException - if a lock prevents the setting of the property and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - if the change would violate a node-type or other constraint and this implementation performs this validation immediately instead of waiting until save.; RepositoryException - If another error occurs.

setProperty

Property setProperty(java.lang.String name,
                     java.lang.String value,
                     int type)
                     throws ValueFormatException,
                            VersionException,

                            ConstraintViolationException,
                            RepositoryException

Sets the specified (single-value) property to the specified value. If the property does not yet exist, it is created.

The type of the property is determined by the type parameter specified.

If the property type specified is not PropertyType.STRING, then a best-effort conversion is attempted. If the conversion fails, a ValueFormatException is thrown.

If the property is not single-valued then a ValueFormatException is also thrown.

If the property already exists it assumes both the new value and the new property type.

Passing a null as the second parameter removes the property. It is equivalent to calling remove on the Property object itself. For example, N.setProperty("P", (Value)null, type) would remove property called "P" of the node in N.

To persist the addition or removal of a property, save must be called on the Session, this Node, or an ancestor of this Node.

A LockException will be thrown either immediately or on save if a lock prevents the setting of the property. Implementations may differ on when this validation is performed.

Parameters:: name - the name of the property to be set.; value - a String object.; type - the type of the property.
Returns:: the Property object set, or null if this method was used to remove a property (by setting its value to null).
Throws:: ValueFormatException - if value cannot be converted to the specified type or if the property already exists and is multi-valued.; VersionException - if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save.; LockException - if a lock prevents the setting of the property and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - if the change would violate a node-type or other constraint and this implementation performs this validation immediately instead of waiting until save.; RepositoryException - if another error occurs.

If the property is multi-valued, a ValueFormatException is also thrown. If another error occurs, a RepositoryException is thrown.

If the node type of this node does not specify a particular property type for the property being set then PropertyType.BINARY is used and, if the property already exists, it assumes both the new value and type PropertyType.BINARY.

Passing a null as the second parameter removes the property. It is equivalent to calling remove on the Property object itself. For example, N.setProperty("P", (InputStream)null) would remove property called "P" of the node in N.

Sets the specified (REFERENCE)property to refer to the specified Node. If the property does not yet exist, it is created. The property type of the property being set is determined by the node type of this node (the one on which this method is being called). If the property type of this property is something other than either PropertyType.REFERENCE or undefined then a ValueFormatException is thrown. If the property is multi-valued, a ValueFormatException is also thrown. If another error occurs, a RepositoryException is thrown.

If the node type of this node does not specify a particular property type for the property being set then PropertyType.REFERENCE is used and, if the property already exists, it assumes both the new value and type PropertyType.REFERENCE.

Passing a null as the second parameter removes the property. It is equivalent to calling remove on the Property object itself. For example, N.setProperty("P", (Node)null) would remove property called "P" of the node in N.

getNode

Node getNode(java.lang.String relPath)
             throws PathNotFoundException,
                    RepositoryException

Returns the node at relPath relative to this node.

If relPath contains a path element that refers to a node with same-name sibling nodes without explicitly including an index using the array-style notation ([x]), then the index [1] is assumed (indexing of same name siblings begins at 1, not 0, in order to preserve compatibility with XPath).

Within the scope of a single Session object, if a Node object has been acquired, any subsequent call of getNode reacquiring the same node must return a Node object reflecting the same state as the earlier Node object. Whether this object is actually the same Node instance, or simply one wrapping the same state, is up to the implementation.

Parameters:: relPath - The relative path of the node to retrieve.
Returns:: The node at relPath.
Throws:: PathNotFoundException - If no node exists at the specified path.; RepositoryException - If another error occurs.

getNodes

NodeIterator getNodes()
                      throws RepositoryException

Returns a NodeIterator over all child Nodes of this Node. Does not include properties of this Node. The same reacquisition semantics apply as with getNode(String). If this node has no child nodes, then an empty iterator is returned.

Returns:: A NodeIterator over all child Nodes of this Node.
Throws:: RepositoryException - If an error occurs.

getNodes

NodeIterator getNodes(java.lang.String namePattern)
                      throws RepositoryException

Gets all child nodes of this node that match namePattern. The pattern may be a full name or a partial name with one or more wildcard characters ("*"), or a disjunction (using the "|" character to represent logical OR) of these. For example,

N.getNodes("jcr:* | myapp:report | my doc")

would return a NodeIterator holding all child nodes of N that are either called 'myapp:report', begin with the prefix 'jcr:' or are called 'my doc'.

Note that leading and trailing whitespace around a disjunct is ignored, but whitespace within a disjunct forms part of the pattern to be matched.

The EBNF for namePattern is:

namePattern ::= disjunct {'|' disjunct} disjunct ::= name [':' name] name ::= '*' | ['*'] fragment {'*' fragment} ['*'] fragment ::= char {char} char ::= nonspace | ' ' nonspace ::= (* Any Unicode character except: '/', ':', '[', ']', '*', ''', '"', '|' or any whitespace character *)

The pattern is matched against the names (not the paths) of the immediate child nodes of this node.

If this node has no matching child nodes, then an empty iterator is returned.

The same reacquisition semantics apply as with getNode(String).

Parameters:: namePattern - a name pattern
Returns:: a NodeIterator
Throws:: RepositoryException - If an unexpected error occurs.

getProperty

Property getProperty(java.lang.String relPath)
                     throws PathNotFoundException,
                            RepositoryException

Returns the property at relPath relative to this node. The same reacquisition semantics apply as with getNode(String).

Parameters:: relPath - The relative path of the property to retrieve.
Returns:: The property at relPath.
Throws:: PathNotFoundException - If no property exists at the specified path.; RepositoryException - If another error occurs.

getProperties

PropertyIterator getProperties()
                               throws RepositoryException

Returns all properties of this node. Returns a PropertyIterator over all properties of this node. Does not include child nodes of this node. The same reacquisition semantics apply as with getNode(String). If this node has no properties, then an empty iterator is returned.

Returns:: A PropertyIterator.
Throws:: RepositoryException - If an error occurs.

getProperties

PropertyIterator getProperties(java.lang.String namePattern)
                               throws RepositoryException

Gets all properties of this node that match namePattern. The pattern may be a full name or a partial name with one or more wildcard characters ("*"), or a disjunction (using the "|" character to represent logical OR) of these. For example,

N.getProperties("jcr:* | myapp:name | my doc")

would return a PropertyIterator holding all properties of N that are either called 'myapp:name', begin with the prefix 'jcr:' or are called 'my doc'.

Note that leading and trailing whitespace around a disjunct is ignored, but whitespace within a disjunct forms part of the pattern to be matched.

The EBNF for namePattern is:

The pattern is matched against the names (not the paths) of the immediate child properties of this node.

If this node has no matching properties, then an empty iterator is returned.

The same reacquisition semantics apply as with getNode(String).

Parameters:: namePattern - a name pattern
Returns:: a PropertyIterator
Throws:: RepositoryException - If an unexpected error occurs.

getPrimaryItem

Item getPrimaryItem()
                    throws ItemNotFoundException,
                           RepositoryException

Returns the primary child item of this node. The primary node type of this node may specify one child item (child node or property) of this node as the primary child item. This method returns that item. If this node does not have a primary item, either because none is declared in the node type or because a declared primary item is not present on this node instance, then this method throws an ItemNotFoundException. The same reacquisition semantics apply as with getNode(String).

Returns:: the primary child item.
Throws:: ItemNotFoundException - if this node does not have a primary child item, either because none is declared in the node type or because a declared primary item is not present on this node instance.; RepositoryException - if another error occurs.

getUUID

java.lang.String getUUID()
                         throws UnsupportedRepositoryOperationException,
                                RepositoryException

Returns the UUID of this node as recorded in this node's jcr:uuid property. This method only works on nodes of mixin node type mix:referenceable. On nonreferenceable nodes, this method throws an UnsupportedRepositoryOperationException. To avoid throwing an exception to determine whether a node has a UUID, a call to isNodeType("mix:referenceable") can be made.

Returns:: the UUID of this node
Throws:: UnsupportedRepositoryOperationException - If this node nonreferenceable.; RepositoryException - If another error occurs.

getIndex

int getIndex()
             throws RepositoryException

This method returns the index of this node within the ordered set of its same-name sibling nodes. This index is the one used to address same-name siblings using the square-bracket notation, e.g., /a[3]/b[4]. Note that the index always starts at 1 (not 0), for compatibility with XPath. As a result, for nodes that do not have same-name-siblings, this method will always return 1.

Returns:: The index of this node within the ordered set of its same-name sibling nodes.
Throws:: RepositoryException - if an error occurs.

getReferences

PropertyIterator getReferences()
                               throws RepositoryException

Returns all REFERENCE properties that refer to this node.

Some level 2 implementations may only return properties that have been saved (in a transactional setting this includes both those properties that have been saved but not yet committed, as well as properties that have been committed). Other level 2 implementations may additionally return properties that have been added within the current Session but are not yet saved.

In implementations that support versioing, this method does not return REFERENCE propertiesthat are part of the frozen state of a version in version storage.

If this node has no references, an empty iterator is returned.

Returns:: A PropertyIterator.
Throws:: RepositoryException - if an error occurs

hasNode

Throws:: RepositoryException - If an unspecified error occurs.

getPrimaryNodeType

NodeType getPrimaryNodeType()
                            throws RepositoryException

Returns the primary node type of this node. Which node type is returned when this method is called on the root node of a workspace is up to the implementation, though the returned type must, of course, be consistent with ther child nodes and properties of the root node.

Returns:: a NodeType object.
Throws:: RepositoryException - if an error occurs

getMixinNodeTypes

NodeType[] getMixinNodeTypes()
                             throws RepositoryException

Returns an array of NodeType objects representing the mixin node types assigned to this node. This includes only those mixin types explicitly assigned to this node, and therefore listed in the property jcr:mixinTypes. It does not include mixin types inherited through the additon of supertypes to the primary type hierarchy.

Returns:: an array of NodeType objects.
Throws:: RepositoryException - if an error occurs

isNodeType

boolean isNodeType(java.lang.String nodeTypeName)
                   throws RepositoryException

                     LockException,
                     RepositoryException

Adds the specified mixin node type to this node. Also adds mixinName to this node's jcr:mixinTypes property immediately. Semantically, the mixin node type assignment may take effect immediately and at the very least, it must take effect on save.

A ConstraintViolationException is thrown either immediately or on save if a conflict with another assigned mixin or the primary node type or for an implementation-specific reason. Implementations may differ on when this validation is done.

In some implementations it may only be possible to add mixin types before a a node is first saved, and not after. I such cases any later calls to addMixin will throw a ConstraintViolationException either immediately or on save.

A NoSuchNodeTypeException is thrown either immediately or on save if the specified mixinName is not recognized. Implementations may differ on when this validation is done.

A VersionException is thrown either immediately or on save if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in. Implementations may differ on when this validation is done.

A LockException is thrown either immediately or on save if a lock prevents the addition of the mixin. Implementations may differ on when this validation is done.

Parameters:: mixinName - the name of the mixin node type to be added
Throws:: NoSuchNodeTypeException - If the specified mixinName is not recognized and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - If the specified mixin node type is prevented from being assigned.; VersionException - if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save..; LockException - if a lock prevents the addition of the mixin and this implementation performs this validation immediately instead of waiting until save.; RepositoryException - if another error occurs.

removeMixin

void removeMixin(java.lang.String mixinName)
                 throws NoSuchNodeTypeException,
                        VersionException,
                        ConstraintViolationException,
                        LockException,
                        RepositoryException

Removes the specified mixin node type from this node. Also removes mixinName from this node's jcr:mixinTypes property immediately. Semantically, the mixin node type removal may take effect immediately and at the very least, it must take effect on save.

If this node does not have the specified mixin, a NoSuchNodeTypeException is thrown either immediately or on save. Implementations may differ on when this validation is done.

A ConstraintViolationException will be thrown either immediately or on save if the removal of a mixin is not allowed. Implementations are free to enforce any policy they like with regard to mixin removal and may differ on when this validation is done.

A LockException is thrown either immediately or on save if a lock prevents the removal of the mixin. Implementations may differ on when this validation is done.

Parameters:: mixinName - the name of the mixin node type to be removed.
Throws:: NoSuchNodeTypeException - if the specified mixinName is not currently assigned to this node and this implementation performs this validation immediately instead of waiting until save.; ConstraintViolationException - if the specified mixin node type is prevented from being removed and this implementation performs this validation immediately instead of waiting until save.; VersionException - if this node is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in and this implementation performs this validation immediately instead of waiting until save.; LockException - if a lock prevents the removal of the mixin and this implementation performs this validation immediately instead of waiting until save..; RepositoryException - if another error occurs.

canAddMixin

boolean canAddMixin(java.lang.String mixinName)
                    throws NoSuchNodeTypeException,
                           RepositoryException

Returns true if the specified mixin node type, mixinName, can be added to this node. Returns false otherwise. A result of false must be returned in each of the following cases:

The mixin's definition conflicts with an existing primary or mixin node type of this node.
This node is versionable and checked-in or is non-versionable and its nearest versionable ancestor is checked-in.
This node is protected (as defined in this node's NodeDefinition, found in the node type of this node's parent).
An access control restriction would prevent the addition of the mixin.
A lock would prevent the addition of the mixin.
An implementation-specific restriction would prevent the addition of the mixin.

A NoSuchNodeTypeException is thrown if the specified mixin node type name is not recognized.

Parameters:: mixinName - The name of the mixin to be tested.
Returns:: true if the specified mixin node type, mixinName, can be added to this node; false otherwise.
Throws:: NoSuchNodeTypeException - if the specified mixin node type name is not recognized.; RepositoryException - if another error occurs.

getDefinition

NodeDefinition getDefinition()
                             throws RepositoryException

Returns the node definition that applies to this node. In some cases there may appear to be more than one definition that could apply to this node. However, it is assumed that upon creation of this node, a single particular definition was used and it is that definition that this method returns. How this governing definition is selected upon node creation from among others which may have been applicable is an implementation issue and is not covered by this specification. The NodeDefinition returned when this method is called on the root node of a workspace is also up to the implementation.

Returns:: a NodeDefinition object.
Throws:: RepositoryException - if an error occurs.
See Also:: NodeType.getChildNodeDefinitions()

checkin

Version checkin()
                throws VersionException,
                       UnsupportedRepositoryOperationException,
                       InvalidItemStateException,
                       LockException,
                       RepositoryException

Creates a new version with a system generated version name and returns that version (which will be the new base version of this node). Sets the jcr:checkedOut property to false thus putting the node into the checked-in state. This means that this node and its connected non-versionable subtree become read-only. A node's connected non-versionable subtree is the set of non-versionable descendant nodes reachable from that node through child links without encountering any versionable nodes. In other words, the read-only status flows down from the checked-in node along every child link until either a versionable node is encountered or an item with no children is encountered.

Read-only status means that an item cannot be altered by the client using standard API methods (addNode, setProperty, etc.). The only exceptions to this rule are the restore(java.lang.String, boolean) (all signatures), Workspace.restore(javax.jcr.version.Version[], boolean), merge(java.lang.String, boolean) and update(java.lang.String) operations; these do not respect read-only status due to check-in. Note that remove of a read-only node is possible, as long as its parent is not read-only (since removal is an alteration of the parent node).

If this node is already checked-in, this method has no effect but returns the current base version of this node.

If this node is not versionable, an UnsupportedRepositoryOperationException is thrown.

A VersionException is thrown or if a child item of this node has an OnParentVersion status of ABORT. This includes the case where an unresolved merge failure exists on this node, as indicated by the presence of the jcr:mergeFailed property.

If there are unsaved changes pending on this node, an InvalidItemStateException is thrown.

Throws a LockException if a lock prevents the checkin.

If checkin succeeds, the change to the jcr:checkedOut property is automatically saved (there is no need to do an additional save).

Returns:: a Version object
Throws:: VersionException - if jcr:predecessors does not contain at least one value or if a child item of this node has an OnParentVersion status of ABORT. This includes the case where an unresolved merge failure exists on this node, as indicated by the presence of a jcr:mergeFailed property.; UnsupportedRepositoryOperationException - If this node is not versionable.; InvalidItemStateException - If unsaved changes exist on this node.; LockException - if a lock prevents the checkin.; RepositoryException - If another error occurs.

checkout

void checkout()
              throws UnsupportedRepositoryOperationException,
                     LockException,
                     RepositoryException

Sets this versionable node to checked-out status by setting its jcr:isCheckedOut property to true and adds to the jcr:predecessors (multi-value) property a reference to the current base version (the same value as held in jcr:baseVersion). This method puts the node into the checked-out state, making it and its connected non-versionable subtree no longer read-only (see checkin() for an explanation of the term "connected non-versionable subtree").

If successful, these changes are persisted immediately, there is no need to call save.

If this node is already checked-out, this method has no effect.

If this node is not versionable, an UnsupportedRepositoryOperationException is thrown.

Throws a LockException if a lock prevents the checkout.

Throws:: UnsupportedRepositoryOperationException - If this node is not versionable.; LockException - if a lock prevents the checkout.; RepositoryException - If another error occurs.

doneMerge

void doneMerge(Version version)
               throws VersionException,
                      InvalidItemStateException,
                      UnsupportedRepositoryOperationException,
                      RepositoryException

Completes the merge process with respect to this node and the specified version.

When the merge(java.lang.String, boolean) method is called on a node, every versionable node in that subtree is compared with its corresponding node in the indicated other workspace and a "merge test result" is determined indicating one of the following:

This node will be updated to the state of its correspondee (if the base version of the correspondee is more recent in terms of version history)
This node will be left alone (if this node's base version is more recent in terms of version history).
This node will be marked as having failed the merge test (if this node's base version is on a different branch of the version history from the base version of its corresponding node in the other workspace, thus preventing an automatic determination of which is more recent).

(See merge(java.lang.String, boolean) for more details)

In the last case the merge of the non-versionable subtree (the "content") of this node must be done by the application (for example, by providing a merge tool for the user).

Additionally, once the content of the nodes has been merged, their version graph branches must also be merged. The JCR versioning system provides for this by keeping a record, for each versionable node that fails the merge test, of the base verison of the corresponding node that caused the merge failure. This record is kept in the jcr:mergeFailed property of this node. After a merge, this property will contain one or more (if multiple merges have been performed) REFERENCEs that point to the "offending versions".

To complete the merge process, the client calls doneMerge(Version v) passing the version object referred to be the jcr:mergeFailed property that the client wishes to connect to this node in the version graph. This has the effect of moving the reference to the indicated version from the jcr:mergeFailed property of this node to the jcr:predecessors.

If the client chooses not to connect this node to a particular version referenced in the jcr:mergeFailed property, he calls cancelMerge(Version version). This has the effect of removing the reference to the specified version from jcr:mergeFailed without adding it to jcr:predecessors.

Once the last reference in jcr:mergeFailed has been either moved to jcr:predecessors (with doneMerge) or just removed from jcr:mergeFailed (with cancelMerge) the jcr:mergeFailed property is automatically removed, thus enabling this node to be checked-in, creating a new version (note that before the jcr:mergeFailed is removed, its OnParentVersion setting of ABORT prevents checkin). This new version will have a predecessor connection to each version for which doneMerge was called, thus joining those branches of the version graph.

If successful, these changes are persisted immediately, there is no need to call save.

A VersionException is thrown if the version specified is not among those referecned in this node's jcr:mergeFailed property.

If there are unsaved changes pending on this node, an InvalidItemStateException is thrown.

An UnsupportedRepositoryOperationException is thrown if this node is not versionable.

A RepositoryException is thrown if another error occurs.

Parameters:: version - a version referred to by this node's jcr:mergeFailed property.
Throws:: VersionException - if the version specifed is not among those referenced in this node's jcr:mergeFailed or if this node is currently checked-in.; InvalidItemStateException - if there are unsaved changes pending on this node.; UnsupportedRepositoryOperationException - if this node is not versionable.; RepositoryException - if another error occurs.

cancelMerge

void cancelMerge(Version version)
                 throws VersionException,
                        InvalidItemStateException,
                        UnsupportedRepositoryOperationException,
                        RepositoryException

Cancels the merge process with respect to this node and specified version.

See doneMerge(javax.jcr.version.Version) for a full explanation. Also see merge(java.lang.String, boolean) for more details.

If successful, these changes are persisted immediately, there is no need to call save.

A VersionException is thrown if the version specified is not among those referecned in this node's jcr:mergeFailed.

An UnsupportedRepositoryOperationException is thrown if this nod is not versionable.

If there are unsaved changes pending on this node, an InvalidItemStateException is thrown.

A RepositoryException is thrown if another error occurs.

Parameters:: version - a version referred to by this node's jcr:mergeFailed property.
Throws:: VersionException - if the version specified is not among those referenced in this node's jcr:mergeFailed or if this node is currently checked-in.; InvalidItemStateException - if there are unsaved changes pending on this node.; UnsupportedRepositoryOperationException - if this node is not versionable.; RepositoryException - if another error occurs.

update

void update(java.lang.String srcWorkspaceName)
            throws NoSuchWorkspaceException,
                   AccessDeniedException,
                   LockException,
                   InvalidItemStateException,
                   RepositoryException

If this node does have a corresponding node in the workspace srcWorkspaceName, then this replaces this node and its subtree with a clone of the corresponding node and its subtree.

If this node does not have a corresponding node in the workspace srcWorkspaceName, then the update method has no effect.

The corresponding node is defined as the node in srcWorkspace with the same UUID as this node or, if this node has no UUID, the same path relative to the nearest ancestor that does have a UUID, or the root node, whichever comes first. This is qualified by the requirment that referencable nodes only correspond with other referencables and non-referenceables with other non-referenceables.

If the update succeeds the changes made are persisted immediately, there is no need to call save.

Note that update does not respect the checked-in status of nodes. An update may change a node even if it is currently checked-in (This fact is only relevant in an implementation that supports versioning).

If the specified srcWorkspace does not exist, a NoSuchWorkspaceException is thrown.

If the current session does not have sufficient rights to perform the operation, then an AccessDeniedException is thrown.

An InvalidItemStateException is thrown if this Session (not necessarily this Node) has pending unsaved changes.

Throws a LockException if a lock prevents the update.

A RepositoryException is thrown if another error occurs.

Parameters:: srcWorkspaceName - the name of the source workspace.
Throws:: NoSuchWorkspaceException - If srcWorkspace does not exist.; InvalidItemStateException - if this Session (not necessarily this Node) has pending unsaved changes.; AccessDeniedException - If the current session does not have sufficient rights to perform the operation.; LockException - if a lock prevents the update.; RepositoryException - If another error occurs.

merge

NodeIterator merge(java.lang.String srcWorkspace,
                   boolean bestEffort)
                   throws NoSuchWorkspaceException,
                          AccessDeniedException,
                          VersionException,
                          LockException,
                          InvalidItemStateException,
                          RepositoryException

This method can be thought of as a version-sensitive update (see 7.1.7 Updating and Cloning Nodes across Workspaces in the specification).

It recursively tests each versionable node in the subtree of this node against its corresponding node in srcWorkspace with respect to the relation between their respective base versions and either updates the node in question or not, depending on the outcome of the test. For details see 8.2.10 Merge in the specification. A MergeException is thrown if bestEffort is false and a versionable node is encountered whose corresponding node's base version is on a divergent branch from this node's base version.

If successful, the changes are persisted immediately, there is no need to call save.

This method returns a NodeIterator over all versionable nodes in the subtree that received a merge result of fail.

If bestEffort is false, this iterator will be empty (since if it merge returns successfully, instead of throwing an exception, it will be because no failures were encountered).

If bestEffort is true, this iterator will contain all nodes that received a fail during the course of this merge operation.

If the specified srcWorkspace does not exist, a NoSuchWorkspaceException is thrown.

If the current session does not have sufficient permissions to perform the operation, then an AccessDeniedException is thrown.

An InvalidItemStateException is thrown if this session (not necessarily this node) has pending unsaved changes.

A LockException is thrown if a lock prevents the merge.

Parameters:: srcWorkspace - the name of the source workspace.; bestEffort - a boolean
Returns:: iterator over all nodes that received a merge result of "fail" in the course of this operation.
Throws:: MergeException - if bestEffort is false and a failed merge result is encountered.; InvalidItemStateException - if this session (not necessarily this node) has pending unsaved changes.; NoSuchWorkspaceException - if srcWorkspace does not exist.; AccessDeniedException - if the current session does not have sufficient rights to perform the operation.; LockException - if a lock prevents the merge.; RepositoryException - if another error occurs.; VersionException

getCorrespondingNodePath

java.lang.String getCorrespondingNodePath(java.lang.String workspaceName)
                                          throws ItemNotFoundException,
                                                 NoSuchWorkspaceException,
                                                 AccessDeniedException,
                                                 RepositoryException

Returns the absolute path of the node in the specified workspace that corresponds to this node.

If no corresponding node exists then an ItemNotFoundException is thrown.

If the specified workspace does not exist then a NoSuchWorkspaceException is thrown.

If the current Session does not have sufficent rights to perform this operation, an AccessDeniedException is thrown.

Parameters:: workspaceName -
Returns:: the absolute path to the corresponding node.
Throws:: ItemNotFoundException - if no corresponding node is found.; NoSuchWorkspaceException - if the workspace is unknown.; AccessDeniedException - if the current session has insufficent rights to perform this operation.; RepositoryException - if another error occurs.

isCheckedOut

boolean isCheckedOut()
                     throws RepositoryException

Returns true if this node is either

<li/>versionable and currently checked-out, <li/>non-versionable and its nearest versionable ancestor is checked-out or <li/>non-versionable and it has no versionable ancestor.

Returns false if this node is either

<li/>versionable and currently checked-in or <li/>non-versionable and its nearest versionable ancestor is checked-in.

Returns:: a boolean
Throws:: RepositoryException - If another error occurs.

restore

void restore(java.lang.String versionName,
             boolean removeExisting)
             throws VersionException,
                    ItemExistsException,
                    UnsupportedRepositoryOperationException,
                    LockException,
                    InvalidItemStateException,
                    RepositoryException

Restores this node to the state defined by the version with the specified versionName.

If this node is not versionable, an UnsupportedRepositoryOperationException is thrown.

If successful, the change is persisted immediately and there is no need to call save.

A VersionException is thrown if no version with the specified versionName exists in this node's version history or if an attempt is made to restore the root version (jcr:rootVersion).

An InvalidItemStateException is thrown if this Session (not necessarily this Node) has pending unsaved changes.

A LockException is thrown if a lock prevents the addition of the mixin.

This method will work regardless of whether this node is checked-in or not.

A UUID collision occurs when a node exists outside the subtree rooted at this node with the same UUID as a node that would be introduced by the restore operation into the subtree at this node. The result in such a case is governed by the removeExisting flag. If removeExisting is true, then the incoming node takes precedence, and the existing node (and its subtree) is removed. If removeExisting is false, then a ItemExistsException is thrown and no changes are made. Note that this applies not only to cases where the restored node itself conflicts with an existing node but also to cases where a conflict occurs with any node that would be introduced into the workspace by the restore operation. In particular, conflicts involving subnodes of the restored node that have OnParentVersion settings of COPY or VERSION are also governed by the removeExisting flag.

Parameters:: versionName - a Version object; removeExisting - a boolean flag that governs what happens in case of a UUID collision.
Throws:: UnsupportedRepositoryOperationException - if versioning is not supported.; VersionException - if the specified version is not part of this node's version history or if an attempt is made to restore the root version (jcr:rootVersion).; ItemExistsException - if removeExisting is false and a UUID collision occurs.; LockException - if a lock prevents the restore.; InvalidItemStateException - if this Session (not necessarily this Node) has pending unsaved changes.; RepositoryException - If another error occurs.

restore

void restore(Version version,
             boolean removeExisting)
             throws VersionException,
                    ItemExistsException,
                    UnsupportedRepositoryOperationException,
                    LockException,
                    RepositoryException

Restores this node to the state defined by the specified version.

If this node is not versionable, an UnsupportedRepositoryOperationException is thrown.

If successful, the change is persisted immediately and there is no need to call save.

A VersionException is thrown if the specified version is not part of this node's version history or if an attempt is made to restore the root version (jcr:rootVersion).

An InvalidItemStateException is thrown if this Session (not necessarily this Node) has pending unsaved changes.

A LockException is thrown if a lock prevents the restore.

This method will work regardless of whether this node is checked-in or not.

Parameters:: version - a Version object; removeExisting - a boolean flag that governs what happens in case of a UUID collision.
Throws:: UnsupportedRepositoryOperationException - if versioning is not supported.; VersionException - if the specified version is not part of this node's version history or if an attempt is made to restore the root version (jcr:rootVersion).; ItemExistsException - if removeExisting is false and a UUID collision occurs.; InvalidItemStateException - if this Session (not necessarily this Node) has pending unsaved changes.; LockException - if a lock prevents the restore.; RepositoryException - if another error occurs.

restore

void restore(Version version,
             java.lang.String relPath,
             boolean removeExisting)
             throws PathNotFoundException,
                    ItemExistsException,
                    VersionException,
                    ConstraintViolationException,
                    UnsupportedRepositoryOperationException,
                    LockException,
                    InvalidItemStateException,
                    RepositoryException

Restores the specified version to relPath, relative to this node.

A node need not exist at relPath, though the parent of relPath must exist, otherwise a PathNotFoundException is thrown.

If a node does exist at relPath then it must correspond to the version being restored (the version must be a version of that node) and must not be a root version (jcr:rootVersion), otherwise a VersionException is thrown.

If no node exists at relPath then a VersionException is thrown if the parent node of relPath is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in.

If there is a node at relPath then the checked-in status of that node itself and the checked-in status of its parent are irrelevant. The restore will work even if one or both are checked-in.

A UUID collision occurs when a node exists outside the subtree rooted at relPath with the same UUID as a node that would be introduced by the restore operation into the subtree at relPath (Note that in cases where there is no node at relPath, this amounts to saying that a UUID collsion occurs if there exists a node anywhere in this workspace with the same UUID as a node that would be introduced by the restore). The result in such a case is governed by the removeExisting flag. If removeExisting is true, then the incoming node takes precedence, and the existing node (and its subtree) is removed. If removeExisting is false, then a ItemExistsException is thrown and no changes are made. Note that this applies not only to cases where the restored node itself conflicts with an existing node but also to cases where a conflict occurs with any node that would be introduced into the workspace by the restore operation. In particular, conflicts involving subnodes of the restored node that have OnParentVersion settings of COPY or VERSION are also governed by the removeExisting flag.

If the would-be parent of the location relPath is actually a property, or if a node type restriction would be violated, then a ConstraintViolationException is thrown.

If the restore succeeds, the changes made to this node are persisted immediately, there is no need to call save.

An InvalidItemStateException is thrown if this Session (not necessarily this Node) has pending unsaved changes.

An UnsupportedRepositoryOperationException is thrown if versioning is not supported.

A LockException is thrown if a lock prevents the restore.

Parameters:: version - a version object; relPath - the path to which the version is to be restored; removeExisting - overns what happens on UUID collision.
Throws:: PathNotFoundException - if the parent of relPath does not exist.; ItemExistsException - if removeExisting is false and a UUID collision occurs; ConstraintViolationException - If the would-be parent of the location relPath is actually a property, or if a node type restriction would be violated; VersionException - if the parent node of relPath is versionable and checked-in or is non-versionable but its nearest versionable ancestor is checked-in or if a node exists at relPath that is not the node corresponding to the specified version or if an attempt is made to restore the root version (jcr:rootVersion).; UnsupportedRepositoryOperationException - if versioning is not supported.; LockException - if a lock prevents the restore.; InvalidItemStateException - if this Session (not necessarily this Node) has pending unsaved changes.; RepositoryException - if another error occurs

                           LockException,
                           InvalidItemStateException,
                           RepositoryException

Restores the version of this node with the specified version label. If this node is not versionable, an UnsupportedRepositoryOperationException is thrown. If successful, the change is persisted immediately and there is no need to call save.

A VersionException is thrown if the specified versionLabel does not exist in this node's version history.

An InvalidItemStateException is thrown if this Session (not necessarily this Node) has pending unsaved changes.

A LockException is thrown if a lock prevents the restore.

This method will work regardless of whether this node is checked-in or not.

A UUID collision occurs when a node exists outside the subtree rooted at this node with the same UUID as a node that would be introduced by the restoreByLabel operation into the subtree at this node. The result in such a case is governed by the removeExisting flag. If removeExisting is true, then the incoming node takes precedence, and the existing node (and its subtree) is removed. If removeExisting is false, then a ItemExistsException is thrown and no changes are made. Note that this applies not only to cases where the restored node itself conflicts with an existing node but also to cases where a conflict occurs with any node that would be introduced into the workspace by the restore operation. In particular, conflicts involving subnodes of the restored node that have OnParentVersion settings of COPY or VERSION are also governed by the removeExisting flag.

Parameters:: versionLabel - a String; removeExisting - a boolean flag that governs what happens in case of a UUID collision.
Throws:: UnsupportedRepositoryOperationException - if versioning is not supported.; VersionException - if the specified versionLabel does not exist in this node's version history.; ItemExistsException - if removeExisting is false and a UUID collision occurs.; LockException - if a lock prevents the restore.; InvalidItemStateException - if this Session (not necessarily this Node) has pending unsaved changes.; RepositoryException - If another error occurs.

Throws:: UnsupportedRepositoryOperationException - if this node is not versionable.; RepositoryException - If another error occurs.

lock

Lock lock(boolean isDeep,
          boolean isSessionScoped)
          throws UnsupportedRepositoryOperationException,
                 LockException,
                 AccessDeniedException,
                 InvalidItemStateException,
                 RepositoryException

Places a lock on this node. If successful, this node is said to hold the lock.

If isDeep is true then the lock applies to this node and all its descendant nodes; if false, the lock applies only to this, the holding node.

If isSessionScoped is true then this lock will expire upon the expiration of the current session (either through an automatic or explicit Session.logout); if false, this lock does not expire until explicitly unlocked or automatically unlocked due to a implementation-specific limitation, such as a timeout.

Returns a Lock object reflecting the state of the new lock and including a lock token. See, in contrast, getLock(), which returns the Lock without the lock token.

The lock token is also automatically added to the set of lock tokens held by the current Session.

If successful, then the property jcr:lockOwner is created and set to the value of Session.getUserID for the current session and the property jcr:lockIsDeep is set to the value passed in as isDeep. These changes are persisted automatically; there is no need to call save.

Note that it is possible to lock a node even if it is checked-in (the lock-related properties will be changed despite the checked-in status).

If this node is not of mixin node type mix:lockable then an LockException is thrown.

If this node is already locked (either because it holds a lock or a lock above it applies to it), a LockException is thrown.

If isDeep is true and a descendant node of this node already holds a lock, then a LockException is thrown.

If the current session does not have sufficient privileges to place the lock, an AccessDeniedException is thrown.

An UnsupportedRepositoryOperationException is thrown if this implementation does not support locking.

An InvalidItemStateException is thrown if this node has pending unsaved changes.

A RepositoryException is thrown if another error occurs.

Parameters:: isDeep - if true this lock will apply to this node and all its descendants; if false, it applies only to this node.; isSessionScoped - if true, this lock expires with the current session; if false it expires when explicitly or automatically unlocked for some other reason.
Returns:: A Lock object containing a lock token.
Throws:: UnsupportedRepositoryOperationException - if this implementation does not support locking.; LockException - if this node is not mix:lockable or this node is already locked or isDeep is true and a descendant node of this node already holds a lock.; AccessDeniedException - if this session does not have permission to lock this node.; InvalidItemStateException - if this node has pending unsaved changes.; RepositoryException - if another error occurs.

getLock

Lock getLock()
             throws UnsupportedRepositoryOperationException,
                    LockException,
                    AccessDeniedException,
                    RepositoryException

Returns the Lock object that applies to this node. This may be either a lock on this node itself or a deep lock on a node above this node.

If this Session (the one through which this Node was acquired) holds the lock token for this lock, then the returned Lock object contains that lock token (accessible through Lock.getLockToken). If this Session does not hold the applicable lock token, then the returned Lock object will not contain the lock token (its Lock.getLockToken method will return null).

If this node is not locked (no lock applies to this node), a LockException is thrown.

If the current session does not have sufficient privileges to get the lock, an AccessDeniedException is thrown.

An UnsupportedRepositoryOperationException is thrown if this implementation does not support locking.

A RepositoryException is thrown if another error occurs.

Returns:: The applicable Lock object, without a contained lock token.
Throws:: UnsupportedRepositoryOperationException - if this implementation does not support locking.; LockException - if no lock applies to this node.; AccessDeniedException - if the curent session does not have pernmission to get the lock.; RepositoryException - if another error occurs.

unlock

void unlock()
            throws UnsupportedRepositoryOperationException,
                   LockException,
                   AccessDeniedException,
                   InvalidItemStateException,
                   RepositoryException

Removes the lock on this node. Also removes the properties jcr:lockOwner and jcr:lockIsDeep from this node. These changes are persisted automatically; there is no need to call save.

If this node does not currently hold a lock or holds a lock for which this Session does not have the correct lock token, then a LockException is thrown. Note however that the system may give permission to some users to unlock locks for which they do not have the lock token. Typically such ?lock-superuser? capability is intended to facilitate administrational clean-up of orphaned open-scoped locks.

Note that it is possible to unlock a node even if it is checked-in (the lock-related properties will be changed despite the checked-in status).

If the current session does not have sufficient privileges to remove the lock, an AccessDeniedException is thrown.

An InvalidItemStateException is thrown if this node has pending unsaved changes.

An UnsupportedRepositoryOperationException is thrown if this implementation does not support locking.

A RepositoryException is thrown if another error occurs.

Throws:: UnsupportedRepositoryOperationException - if this implementation does not support locking.; LockException - if this node does not currently hold a lock or holds a lock for which this Session does not have the correct lock token; AccessDeniedException - if the current session does not have permission to unlock this node.; InvalidItemStateException - if this node has pending unsaved changes.; RepositoryException - if another error occurs.

holdsLock

boolean holdsLock()
                  throws RepositoryException

Returns true if this node holds a lock; otherwise returns false. To hold a lock means that this node has actually had a lock placed on it specifically, as opposed to just having a lock apply to it due to a deep lock held by a node above.

Returns:: a boolean.
Throws:: RepositoryException - if an error occurs.

isLocked

boolean isLocked()
                 throws RepositoryException

Returns true if this node is locked either as a result of a lock held by this node or by a deep lock on a node above this node; otherwise returns false.

Returns:: a boolean.
Throws:: RepositoryException - if an error occurs.
