public interface TreeNode

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.


Method Summary
 Enumeration children()
          Returns the children of the receiver as an Enumeration.

Method Detail

getChildAt

TreeNode getChildAt(int childIndex)
Returns the child TreeNode at index childIndex.


getChildCount

int getChildCount()
Returns the number of children TreeNodes the receiver contains.


getParent

TreeNode getParent()
