org.objectweb.jonas_ejb.container.JEntitySwitchCRC
JEntitySwitch is used internally to synchronize accesses to the entity context and thus to the entity bean instance. All parts common to EJBObject and EJBLocalObject should be here. Different policies can be applied to manage context/instance pairs: - only 1 pair (container manages the transaction isolation) - 1 pair for each transaction (transaction isolation managed by DataBase) - 2 pairs (1 for transactional accesses, 1 for non transaction accesses)
