## CGAL::Triangulation_ds_vertex_base_2<Tds>

### Definition

The class Triangulation_ds_vertex_base_2 can be used as the base vertex for a Triangulation_data_structure_2, it is a model of the concept TriangulationDSVertexBase_2.

This base class can be used directly or can serve as a base to derive other base classes with some additional attributes (a color for example) tuned for a specific application.

Note that if the Triangulation_data_structure_2 is used as a parameter of a geometric triangulation, there are additionnal geometric requirements to be fulfilled by the vertex base class, and Triangulation_ds_vertex_base_2 cannot be plugged in.
