#include <Concepts/TriangulationVertexBase_2.h>

Definition

The concept TriangulationVertexBase_2 describes the requirements for the vertex base class of a triangulation data structure to be plugged in a basic, Delaunay or constrained triangulations.

The concept TriangulationVertexBase_2 refines the concept TriangulationDSVertexBase_2 adding geometric information: the vertex base of a triangulation stores a point.

Types
typedef unspecified_type	Point
	Must be the same as the point type `TriangulationTraits_2::Point_2` defined by the geometric traits class of the triangulation.

Creation
	TriangulationVertexBase_2 (Point p)
	constructs a vertex embedded in point `p`.

	TriangulationVertexBase_2 (Point p, Face_handle f)
	constructs a vertex embedded in point `p` and pointing on face `f`.

Access Functions
Point	point () const
	returns the point.

Setting
void	set_point (Point p)
	sets the point.

istream &	operator>> (istream &is, TriangulationVertexBase_2 &v)
	Inputs the non-combinatorial information given by the vertex: the point and other possible information.

ostream &	operator<< (ostream &os, const TriangulationVertexBase_2 &v)
	Outputs the non combinatorial operation given by the vertex: the point and other possible information.
