public class OutlineNodeDefault

extends DefaultMutableTreeNode

implements OutlineNode

OutlineNodeDefault: TreeNode class which extends DefaultMutableTreeNode by enabling each node to have its own renderer, to keep a second object used to compute a label, and to keep track of whether its children have been computed. Most uses will not need to derive classes (exception: adding more state); most behavior is handled by OutlineRenderer so that alternate views can be created simply by changing this nodes' renderer.
