Class TransientNode

java.lang.Object
  helma.objectmodel.TransientNode

All Implemented Interfaces:

IPathElement, INode, INodeState, java.io.Serializable

public class TransientNode
extends java.lang.Object
implements INode, java.io.Serializable

A transient implementation of INode. An instance of this class can't be made persistent by reachability from a persistent node. To make a persistent-capable object, class helma.objectmodel.db.Node has to be used.
