#include <CGAL/Triangulation_vertex_base_with_id_2.h>

Inherits from

TriangulationVertexBase_2.

Definition

The class Triangulation_vertex_base_with_id_2 is a model of the concept TriangulationVertexBase_2, the base vertex of a 2D-triangulation.

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

Note that the user is in charge of setting indices correctly before running a graph algorithm.

Template Parameters
TriangulationTraits_2is the geometric traits class and must be a model of TriangulationTraits_2.
TriangulationVertexBase_2must be a vertex base class from which Triangulation_vertex_base_with_id_2 derives. It has the default value Triangulation_vertex_base_2<TriangulationTraits_2>.
Is Model Of:
TriangulationVertexBase_2
