public interface TreeNode

Disabled: no SafeJ information.

Defines the requirements for an object that can be used as a tree node in a JTree.

Implementations of TreeNode that override equals will typically need to override hashCode as well. Refer to TreeModel for more information. For further information and examples of using tree nodes, see How to Use Tree Nodes in The Java Tutorial.
