java.lang.Object
  org.jhotdraw.util.Bounds

All Implemented Interfaces:

java.io.Serializable

public class Bounds
extends java.lang.Object
implements java.io.Serializable

This class is a rectangle with floating point dimensions and location. This class provides many convenient geometrical methods related to rectangles. Basically, this class is like java.awt.geom.Rectangle2D with some extra functionality.
