Class Rectangle

java.lang.Object

com.marcosavard.commons.geom.Shape

com.marcosavard.commons.geom.Rectangle

All Implemented Interfaces:

HasArea, HasBounds

public class Rectangle
extends Shape

An implementation that describes a rectangle, like java.awt.Rectangle, but 1) purely mathematical, does not depend on java.awt, so can be used in GWT or other environments where dependency to AWT is not allowed. 2) Immutable implementation, so if it is stored in a structure, a client cannot gain access to this rectangle and change its properties. 3) Add additional methods not implemented in java.awt.Rectangle.
