Class CLine

java.lang.Object
  org.shapelogic.polygon.CLine

All Implemented Interfaces:

java.lang.Comparable<ILine2D>, GeometricShape2D, ILine2D, PointReplacable<CLine>

public class CLine
extends java.lang.Object
implements ILine2D, PointReplacable<CLine>

Class for line. Works for both double and int based points. Can be used for both undirected and directed lines I think this is made to be immutable, but points are not. But in order to have the sort work for lines I have to assume that the points in it are not moving.
