CGAL 5.1.2 - CGAL and the Boost Graph Library
CGAL::Triangulation_face_base_with_id_2< TriangulationTraits_2, TriangulationFaceBase_2 > Class Template Reference

#include <CGAL/Triangulation_face_base_with_id_2.h>

Inherits from

TriangulationFaceBase_2.

Definition

The class Triangulation_face_base_with_id_2 is a model of the concept TriangulationFaceBase_2, the base face of a 2D-triangulation.

It provides an integer field that can be used to index faces for Bgl algorithms.

Note that the user is in charge of setting indices correctly before running a graph algorithm, by calling the function CGAL::set_triangulation_ids(Triangulation&).

Template Parameters
TriangulationTraits_2is the geometric traits class and must be a model of TriangulationTraits_2.
TriangulationFaceBase_2must be a face base class from which Triangulation_face_base_with_id_2 derives. It has the default value Triangulation_face_base_2<TriangulationTraits_2>.
Is Model Of:
TriangulationFaceBase_2

Access Functions

int id () const
 Returns the index.
 
int & id ()
 Returns a reference to the index stored in the face.
