Class CirclemapNode

java.lang.Object

ch.randelshofer.tree.circlemap.Circle

ch.randelshofer.tree.circlemap.CirclemapNode

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

CirclemapCompositeNode

public class CirclemapNode
extends Circle

The CirclemapNode class encapsulates a TreeNode whithin a CirclemapTree.

It holds the radius of the data as an absolute value. The location is held relative to the center of the parent data.

This data can layout its subtree in a space-filling circular treemap.
