public interface ProxyManager
Manager for copying and proxying second class objects. Second class objects are those that are often used as fields of persistent or transactional instances, and which can themselves be modified without resetting the owning class' field. Because these types can change without an explicit call to the owning persistence capable instance, special care must be taken to ensure that their state is managed correctly. Specifically, they must be copied when saving state for rollback, and they must be proxied for any instance whose state is managed by a state manager, where proxying involves creating a second class object that automaticlly notifies its owning instance whenever it is modified. Generally, this factory is only used by the implementation; second class object handling is transparent to client code.
