Examples of org.datanucleus.state.StateManager

org.datanucleus.state.StateManager
StateManager for a persistable object. Based around the JDO PersistenceCapable contract. Makes the assumption that a StateManager corresponds to ONE persistable object.

        if (isDetached(pc))
        {
            ExecutionContext ec = ((JDOPersistenceManager)pm).getObjectManager();


            // Temporarily attach a StateManager to access the detached field information
            StateManager sm = (StateManager) ObjectProviderFactory.newForDetached(ec, pc, getObjectId(pc), null);
            pc.jdoReplaceStateManager((javax.jdo.spi.StateManager) sm);
            sm.retrieveDetachState(sm);
            String[] dirtyFieldNames = sm.getDirtyFieldNames();
            pc.jdoReplaceStateManager(null);


            return dirtyFieldNames;
        }
        else
        {
            ExecutionContext ec = ((JDOPersistenceManager)pm).getObjectManager();
            ObjectProvider sm = ec.findObjectProvider(pc);
            if (sm == null)
            {
                return null;
            }
