## CGAL::Triangulation_vertex_base_2<Traits,Vb>

### Definition

The class Triangulation_vertex_base_2<Traits,Vb> is the default model for the concept TriangulationVertexBase_2.

Triangulation_vertex_base_2<Traits,Vb> can be simply plugged in the triangulation data structure of a triangulation, or used as a base class to derive other base vertex classes tuned for specific applications.

#include <CGAL/Triangulation_vertex_base_2.h>

### Parameters

Triangulation_vertex_base_2<Traits,Vb> is templated by a geometric traits class which provide the type Point. It is strongly recommanded to instantiate this traits class with the model used for the triangulation traits class. This ensures that the point type defined by Triangulation_vertex_base_2<Traits,Vb> is the same as the point type defined by the triangulation.

The second template parameter of Triangulation_vertex_base_2<Traits,Vb> has to be a model of the concept TriangulationDSVertexBase_2 By default this parameter is instantiated by CGAL::Triangulation_ds_vertex_base_2<>.

### Is Model for the Concept
