Class Cluster

java.lang.Object
  software.common.Cluster

All Implemented Interfaces:

java.io.Serializable

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

A cluster has a center of mass, is in a rectangle of coordonates ((xmin,ymin),(xmax,ymax)) and containes a number of points (different from the number of points in the rectangle) A cluster is only a wrapper around those values
