#include <CGAL/Triangulation_vertex.h>

Definition

template<typename TriangulationTraits_, typename Data, typename TriangulationDSVertex_>
class CGAL::Triangulation_vertex< TriangulationTraits_, Data, TriangulationDSVertex_ >

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

<tt>TriangulationTraits_</tt>	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.
<tt>TriangulationDSVertex_</tt>	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:

Data

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.

Point

template<typename TriangulationTraits_ , typename Data , typename TriangulationDSVertex_ >

typedef TriangulationTraits_::Point_d CGAL::Triangulation_vertex< TriangulationTraits_, Data, TriangulationDSVertex_ >::Point

The point type.

Constructor & Destructor Documentation

Triangulation_vertex() [1/3]

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.
