Annotation Type CloneCopyPolicy

@Target(TYPE) @Retention(RUNTIME) public @interface CloneCopyPolicy
A CloneCopyPolicy is used to set an org.eclipse.persistence.descriptors.copying.CloneCopyPolicy on an Entity. A CloneCopyPolicy must specify at one or both of the "method" or "workingCopyMethod". "workingCopyMethod" is used to clone objects that will be returned to the user as they are registered in EclipseLink's transactional mechanism, the UnitOfWork. "method" will be used for the clone that is used for comparison in conjunction with EclipseLink's DeferredChangeDetectionPolicy A CloneCopyPolicy should be specified on an Entity, MappedSuperclass or Embeddable. Example: @Entity @CloneCopyPolicy(method="myCloneMethod") or: @Entity @CloneCopyPolicy(method="myCloneMethod", workingCopyMethod="myWorkingCopyCloneMethod") or: @Entity @CloneCopyPolicy(workingCopyMethodName="myWorkingCopyClone")
