java.lang.Objectorg.eclipse.persistence.descriptors.copying.AbstractCopyPolicy
org.eclipse.persistence.descriptors.copying.CloneCopyPolicy
public class CloneCopyPolicy
Purpose: Allows a clone of an object to be created with a method that returns the cloned object. It is possible to define methods for two types of clones 1. methodName can be set to define the method EclipseLink uses to clone objects for it's own internal use. The objects created by this method will not be visible to the user, and instead used as a basis for comparison when a DeferredChangeDetectionPolicy used. This method will also be in place of the workingCopyMethod if it is not provided 2. workingCopyMethod this method is used to create the clone that is returned to the user when an Object is registered in a UnitOfWork
