`#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 to set the index correctly before running a graph algorithm.

Template Parameters

  TriangulationTraits_2 | is the geometric traits class and must be a model of `TriangulationTraits_2` which provides the `Point_2`.
  TriangulationVertexBase_2 | must 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`

See Also
  `CGAL::Triangulation_vertex_base_2`

Examples:
  BGL_triangulation_2/dijkstra_with_internal_properties.cpp.

## Access Functions
int | id () const
| Returns the index.
int & | id ()
