Class Vertex2D

java.lang.Object
  cz.cuni.utils.math.Tuple2D
      cz.cuni.utils.math.extended.Vertex2D

All Implemented Interfaces:

java.lang.Cloneable

public class Vertex2D
extends Tuple2D

It differs from Tuple2D in the way, that xy shouldn't be changed after Vertex2D was created, because hash code was counted from them.

Field Summary

protected int

hashCode Hash code is counted upon creation of the object and is counted only from xyz[] ... don't change xyz[] afterwards!
