helma.objectmodel.db.NodeHandle

This class is a handle or reference to a Node. This is to abstract from different methods of reference: Transient Nodes are referred to directly, while persistent nodes are referred to via key/node manager. A handle is used to refer to a node in a safe way over a longer period. While a direct reference may point to a node that has been evicted from the cache and reinstanciated since being set, NodeHandle will always return an up-to-date instance of its node. Helma tries to ensure the following rules on NodeHandles:

For transient nodes there exists only one NodeHandle.
If a transient node becomes persistent its node handle is notified and converted into a persistent NodeHandle.

These two properties guarantee that NodeHandle comparisons are easy and usually correct.

                    Session session = sessionArray[i];


                    session.pruneUploads();
                    if ((now - session.lastTouched()) > (sessionTimeout * 60000)) {
                        NodeHandle userhandle = session.userHandle;


                        if (userhandle != null) {
                            try {
                                Object[] param = {session.getSessionId()};
