Class DPoint

java.lang.Object
  |
  +--com.javaranch.common.DPoint

All Implemented Interfaces:

java.io.Serializable

public class DPoint

extends java.lang.Object

implements java.io.Serializable

A very lean serialized point type where X and Y are of type double.

Should the day ever arise that everyone supports Java 1.2 or higher, this class should inherit Point2D.Double.
