java.lang.Object
Jcg.triangulations2D.TriangulationDSVertex_2<X>
All Implemented Interfaces:
Comparable<TriangulationDSVertex_2<X>>
public class TriangulationDSVertex_2<X extends Point_> extends Object implements Comparable<TriangulationDSVertex_2<X>>
The class represents a vertex of a 2D triangulation. Each vertex stores a pointer to one of its incident faces.
