diva.util.java2d.Polygon2D

A polygon shape. This class implements java.awt.Shape, and consists of a series of straight-line segments. This class should be used instead of GeneralPath for shapes that consist only of straight-line segments and are always closed. It is more efficient than GeneralPath, and allows the coordinates of vertices to be modified. Following the convention set by the Java2D shape classes, the Polygon class is an abstract class, which contains two concrete inner classes, one storing floats and one storing doubles. @version $Id: Polygon2D.java,v 1.14 2005/07/08 19:55:18 cxh Exp $ @author John Reekie
