Annotation Interface CloneCopyPolicy

@Target(TYPE)
@Retention(RUNTIME)
public @interface CloneCopyPolicy

A CloneCopyPolicy is used to set an CloneCopyPolicy on an Entity. A CloneCopyPolicy must specify at least 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() is used for the clone that is used for comparison in conjunction with EclipseLink's DeferredChangeDetectionPolicy.

A CloneCopyPolicy can be specified on an Entity, MappedSuperclass or Embeddable.

Example:

 @Entity
 @CloneCopyPolicy(method="myCloneMethod")

or:

 @Entity
 @CloneCopyPolicy(method="myCloneMethod", workingCopyMethod="myWorkingCopyCloneMethod")

 @Entity
 @CloneCopyPolicy(workingCopyMethodName="myWorkingCopyClone")
