TriangulationOnSphereVertexBase_2 Concept Reference

Definition

Refines

TriangulationDSVertexBase_2

The concept TriangulationOnSphereVertexBase_2 describes the requirements for the vertex base class of a triangulation data structure to be plugged in a triangulation on the sphere. It 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 equivalent to the point type Point_on_sphere_2 of the concept TriangulationOnSphereTraits_2.
typedef unspecified_type	Face_handle
	Must be the equivalent to the point type Face_handle of the triangulation.

Creation
	TriangulationOnSphereVertexBase_2 (Point p)
	constructs a vertex whose geometric embedding is the point p.
	TriangulationOnSphereVertexBase_2 (Point p, Face_handle f)
	constructs a vertex whose geometric embedding is the point p and pointing to face f.

Access Functions
Point	point () const
	returns the point.

Setting
void	set_point (Point p)
	sets the point.
std::istream &	operator>> (std::istream &is, TriangulationOnSphereVertexBase_2 &v)
	inputs the non-combinatorial information given by the vertex: the point and other possible information.
std::ostream &	operator<< (std::ostream &os, const TriangulationOnSphereVertexBase_2 &v)
	outputs the non combinatorial operation given by the vertex: the point and other possible information.

Constructor & Destructor Documentation

TriangulationOnSphereVertexBase_2()

TriangulationOnSphereVertexBase_2::TriangulationOnSphereVertexBase_2	(	Point	p,
		Face_handle	f
	)

constructs a vertex whose geometric embedding is the point p and pointing to face f.

Face_handle is the type defined the triangulation data structure used in the Delaunay triangulation on the sphere.
