All Implemented Interfaces:

SecondaryAnnotationWorker

public class InitialValueAnnotationWorker
extends java.lang.Object
implements SecondaryAnnotationWorker

Looks for InitialValue annotations on methods that don't have a Persist annotation (that's handled by PersistAnnotationWorker); adds an IPropertySpecification for the property, so that its initial value may be set.
