TriangulationVertexBase_3 Concept Reference

Definition

The vertex base used by the geometric triangulation must store a point. So we list here the additional requirements compared to a vertex base usable for the triangulation data structure.

Types
typedef unspecified_type	Point
	Must be the same as the point type TriangulationTraits_3::Point_3 defined by the geometric traits class of the triangulation.

Creation
	TriangulationVertexBase_3 (const Point &p)
	Constructs a vertex whose geometric embedding is point p.
	TriangulationVertexBase_3 (const Point &p, Cell_handle c)
	Constructs a vertex embedding the point p and pointing to cell c.

Access Functions
Point	point () const
	Returns the point.

Setting
void	set_point (Point p)
	Sets the point.

I/O
istream &	operator>> (istream &is, TriangulationVertexBase_3 &v)
	Inputs the non-combinatorial information given by the vertex: the point and other possible information.
ostream &	operator<< (ostream &os, const TriangulationVertexBase_3 &v)
	Outputs the non-combinatorial information given by the vertex: the point and other possible information.
