java.lang.Object
- org.openide.nodes.DefaultHandle

All Implemented Interfaces:

java.io.Serializable, Node.Handle
```
public final class DefaultHandle
extends java.lang.Object
implements Node.Handle
```
Simple implementation of Node.Handle. When created by createHandle(org.openide.nodes.Node) it looks for the parent of the node and stores the node's name. When getNode() is then called, it tries to restore the parent and then to walk down to the child.
Note that if most nodes use DefaultHandle, this may walk up to the root recursively. Otherwise, some other sort of handle may provide the termination case.
