Method Detail

getBase

public final SourceDefinition getBase()

Gets the SourceDefinition for the Source that you used to produce the Source for this DerivedDefinition. For example, the following code calls a join method of sourceA to produce aByB, and then gets the SourceDefinition, aByBDefinition, for aByB. Calling the getSource method of aByBDefinition returns baseOfAByB, which is sourceA.

 Source aByB = sourceA.join(sourceB);
 SourceDefinition aByBDefinition = aByB.getDefinition();
 Source baseOfAbyB = aByBDefinition.getSource();
 

Returns:

The SourceDefinition for the Source that you used to produce the Source for this DerivedDefinition.
