org.eclipse.persistence.descriptors.changetracking.ObjectChangeTrackingPolicy
public class ObjectChangeTrackingPolicy
PUBLIC: A ObjectChangeTrackingPolicy allows an object to calculate for itself whether it should has changed by implementing ChangeTracker. Changed objects will be processed in the UnitOfWork commit process to include any changes in the results of the commit. Unchanged objects will be ignored.
