TreeNode
- public class DefaultTreeForTreeLayout<TreeNode>
Provides a generic implementation for the TreeForTreeLayout
interface, applicable to any type of tree node.
It allows you to create a tree "from scratch", without creating any new class.
To create a tree you must provide the root of the tree (see
DefaultTreeForTreeLayout(Object)
. Then you can incrementally
construct the tree by adding children to the root or other nodes of the tree
(see addChild(Object, Object)
and
addChildren(Object, Object...)
).
