CGAL::Triangulation_vertex< TriangulationTraits, Data, TriangulationDSVertex > Class Template Reference

#include <CGAL/Triangulation_vertex.h>

Definition

The class Triangulation_vertex is a model of the concept TriangulationVertex.

It is used by default for representing vertices in the class Triangulation<TriangulationTraits, TriangulationDataStructure>.

A Triangulation_vertex stores a point and an incident full cell.

Template Parameters

TriangulationTraits	must be a model of the concept TriangulationTraits. It provides geometric types and predicates for use in the Triangulation<TriangulationTraits, TriangulationDataStructure> class. It is of interest here for its declaration of the Point type.
Data	is an optional type of data to be stored in the vertex class. The class template Triangulation_vertex accepts that no second parameter be specified. In this case, Data defaults to CGAL::No_vertex_data. CGAL::No_vertex_data can be explicitely specified to allow to access the third parameter.
TriangulationDSVertex	must be a model of the concept TriangulationDSVertex. The class template Triangulation_vertex accepts that no third parameter be specified. It also accepts the tag CGAL::Default as third parameter. In both cases, TriangulationDSVertex defaults to CGAL::Triangulation_ds_vertex<>.

Is Model Of:

TriangulationVertex Additionally, the class Triangulation_vertex provides the following types, constructors and methods:

Creation
template<typename T >
	Triangulation_vertex (Full_cell_handle c, const Point &p, const T &t)
	Constructs a vertex with incident full cell c. More...
template<typename T >

	Triangulation_vertex ()
	Same as above, but with default-constructed Point and Data.

Data access

	Returns a const reference to the stored data.
Data &	data ()
	Returns a non-const reference to the stored data.
std::istream &	operator>> (std::istream &is, Triangulation_vertex &v)

Member Typedef Documentation

template<typename TriangulationTraits , typename Data , typename TriangulationDSVertex >

typedef Data CGAL::Triangulation_vertex< TriangulationTraits, Data, TriangulationDSVertex >::Data

The type of the additional data stored in the vertex.

If you read a Triangulation_vertex from a stream (a file) or write a Triangulation_vertex to a stream, then streaming operators << and >> must be provided for this type.

template<typename TriangulationTraits , typename Data , typename TriangulationDSVertex >

template<typename T >

CGAL::Triangulation_vertex< TriangulationTraits, Data, TriangulationDSVertex >::Triangulation_vertex	(	Full_cell_handle	c,
		const Point &	p,
		const T &	t
	)

Constructs a vertex with incident full cell c.

The vertex is embedded at point p and the parameter t is passed to the Data constructor.

		const Triangulation_vertex< TriangulationTraits, Data, TriangulationDSVertex > &	v
	)

Outputs the non-combinatorial information given by the vertex, i.e., the point and other possible information.

The data of type Data is also written.

	)

Inputs the non-combinatorial information given by the vertex, i.e., the point and other possible information.

The data of type Data is also read.
