CGAL 5.6  2D Triangulation Data Structure

#include <CGAL/Triangulation_ds_vertex_base_2.h>
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 additional geometric requirements to be fulfilled by the vertex base class, and Triangulation_ds_vertex_base_2
cannot be plugged in.
TDS  should not be specified (see Section The Rebind Mechanism and examples)
