Class KaboumEdge

java.lang.Object
  org.kaboum.geom.KaboumEdge

public class KaboumEdge
extends java.lang.Object

This class define an edge i.e. an oriented segment defined by a start point and an end point. This edge can be labeled as refered to Klamer Schutte algorithm (cf. "An edge labeling approach to concave polygon cliping", Klamer Schutte, PREPRINT submitted 7 july 1995 to ACM Transcations on Graphics).
