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 to set the index correctly before running a graph algorithm.
#include <CGAL/Triangulation_vertex_base_with_id_2.h>
The first template argument is the geometric traits class TriangulationTraits_2 which provides the Point_2.
The second template argument is a vertex base class from which Triangulation_vertex_base_with_id_2 derives. It has the default value Triangulation_vertex_base_2<TriangulationTraits_2>.
