javax.swing.tree.DefaultMutableTreeNode

edu.nyu.jet.concepts.Concept

All Implemented Interfaces:

Transferable, Serializable, Cloneable, MutableTreeNode, TreeNode

public class Concept
extends DefaultMutableTreeNode
implements Transferable

A Concept is basically a DefaultMutableTreeNode. Its userObject is its name as a String. It allows children who can be either a Concept or a word.

Concept instances are transferable.
