All Implemented Interfaces:

java.awt.Shape, java.io.Serializable, java.lang.Cloneable

Direct Known Subclasses:

RectmapCompositeNode

public class RectmapNode
extends java.awt.geom.Rectangle2D.Double

The RectmapNode encapsulatets a TreeNode whithin a RectmapTree.

It holds the width and height of the node as an absolute value. The location is held relative to the location of the parent node.

This node can layout its subtree in a space-filling rectangular treemap.
