jApp
Class Point2d

java.lang.Object
  jApp.Point2d

All Implemented Interfaces:

java.io.Serializable

public final class Point2d
extends java.lang.Object
implements java.io.Serializable

Implements a 2D point with double precision coordinates. This is very similar to Point2D.Double in java.awt.geom package. The excistence of this class and especially the package (xApp) it resides in is a historical accident. In the future this class will be emigrated to the 'myjapp' package once a viable imigration stategy has been thought out.

IMPORTANT NOTICE

Serialization of instances of this class is strongly discouraged, as changing the package will inevitably break compatibility of serialized objects.
