#include <CGAL/HalfedgeDS_vertex_base.h>

Definition

template<typename Refs>
class CGAL::HalfedgeDS_vertex_base< Refs >

The class HalfedgeDS_vertex_base is a model of the HalfedgeDSVertex concept.

Refs is an instantiation of a HalfedgeDS. The template declaration of HalfedgeDS_vertex_base has three parameters with some defaults that allow to select various flavors of vertices. The declaration is best explained with the two following declarations, essentially hiding an implementation dependent default setting:

template <class Refs, class T = CGAL::Tag_true>
class HalfedgeDS_vertex_base;

template <class Refs, class T, class Point>
class HalfedgeDS_vertex_base;

Let us look at some instantiations

• HalfedgeDS_vertex_base defines a vertex including a reference to an incident halfedge.
• HalfedgeDS_vertex_base<Refs,CGAL::Tag_false> is a vertex without a reference to an incident halfedge. It is empty besides the required type definitions. It can be used for deriving own vertex implementations. See also CGAL::HalfedgeDS_vertex_min_base<Refs>.
• HalfedgeDS_vertex_base<Refs,CGAL::Tag_true,Point> is a vertex with a reference to an incident halfedge and it stores a point of type Point. It can be used as a vertex for a model of the PolyhedronItems_3 concept.
• HalfedgeDS_vertex_base<Refs,CGAL::Tag_false,Point> is a vertex without a reference to an incident halfedge and it stores a point of type Point. It can be used as a vertex for a model of the PolyhedronItems_3 concept.
