CGAL::HalfedgeDS_face_base< Refs > Class Template Reference

#include <CGAL/HalfedgeDS_face_base.h>

Definition

The class HalfedgeDS_face_base is a model of the HalfedgeDSFace concept.

Refs is an instantiation of a HalfedgeDS. The template declaration of HalfedgeDS_face_base has three parameters with some defaults that allow to select various flavors of faces. 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_face_base;

template <class Refs, class T, class Plane>

class HalfedgeDS_face_base;

HalfedgeDS_face_base defines a face including a reference to an incident halfedge.

CGAL::HalfedgeDS_face_base<Refs,CGAL::Tag_false> is a face without a reference to an incident halfedge. It is empty besides the required type definitions. It can be used for deriving own faces. See also CGAL::HalfedgeDS_face_min_base<Refs>.

CGAL::HalfedgeDS_face_base<Refs,CGAL::Tag_true,Plane> is a face with a reference to an incident halfedge and it stores a plane equation of type Plane. It can be used as a face for a model of the PolyhedronItems_3 concept.

CGAL::HalfedgeDS_face_base<Refs,CGAL::Tag_false,Plane> is a face without a reference to an incident halfedge and it stores a plane equation of type Plane. It can be used as a face for a model of the PolyhedronItems_3 concept.
