java.lang.Object
  org.apache.myfaces.trinidaddemo.TreeModelAdapter

All Implemented Interfaces:

Serializable

public class TreeModelAdapter
extends Object
implements Serializable

This class facilitates the construction of a ChildPropertyTreeModel instance via managed-beans. ChildPropertyTreeModel does not have a no-arg constructor. This class does, and so can be instantiated as a managed-bean. Two properties need to be set: "childProperty" and "instance"
