This class provides a way to find out what entities are contained in what transaction. It is used, to find which entities to call ejbStore() on when a ejbFind() method is called within a transaction. EJB 2.0- 9.6.4 also, it is used to synchronize on a remove. Used in EntitySynchronizationInterceptor, EntityContainer Entities are stored in an ArrayList to ensure specific ordering.
