CGAL 5.2.1  2D Triangulation

#include <CGAL/Triangulation_vertex_base_with_info_2.h>
The class Triangulation_vertex_base_with_info_2
is designed to be used as a base vertex class of a triangulation.
It provides an easy way to add some user defined information in vertices.
Info  is the information the user would like to add to a vertex. It has to be DefaultConstructible and Assignable . 
Traits  is the geometric traits class which provides the Point_2 . It is strongly recommended to instantiate this parameter with the traits class used for the triangulation. This ensures that the point type defined by Triangulation_vertex_base_with_info_2 matches the point type defined by the triangulation. 
Vb  must be a vertex base class from which Triangulation_vertex_base_with_info_3 derives. By default this parameter is instantiated by Triangulation_vertex_base_2<Traits> . 
TriangulationVertexBaseWithInfo_2
The parameter Vb
is a model of some vertex base concept. Triangulation_vertex_base_with_info_2
derives from Vb
and will be a model of the same vertex base concept: TriangulationVertexBase_2
, or RegularTriangulationVertexBase_2
.

Access Functions  
const Info &  info () const 
Returns a const reference to the object of type Info stored in the vertex.  
Info &  info () 
Returns a reference to the object of type Info stored in the vertex.
