All Implemented Interfaces:

Cloneable, Serializable, Shape

public class TimedPolygon2D

extends Polygon2D

implements Serializable, Cloneable

A polygon that also has timing information.

This implementation is not yet optimized for space. The difficulty lies in the design decision made by Javasoft to make the arrays in Polygon directly accessible, which can improve performance but make other optimizations much more difficult since there is no abstraction.
