public class Ellipse2DNode
extends java.awt.geom.Ellipse2D.Double
implements NodeShape

Ellipse2DNode class implements NodeShape for it is an Ellipse NodeShape that can be used as a node in a tree.

Because it is simply a Shape that also implements getInscribedRectangle, it therefore can use all methods defined within Ellipse2DNode.
