## CGAL::Triangulation_vertex_base_with_info_3<Info, TriangulationTraits_3, TriangulationVertexBase_3>

### Definition

The class Triangulation_vertex_base_with_info_3 is a model of the concept TriangulationVertexBase_3, the base vertex of a 3D-triangulation. It provides an easy way to add some user defined information in vertices. Note that input/output operators discard this additional information.

#include <CGAL/Triangulation_vertex_base_with_info_3.h>

### Parameters

The first template argument is the information the user would like to add to a vertex. It has to be DefaultConstructible and Assignable.

The second template argument is the geometric traits class TriangulationTraits_3 which provides the Point_3.

The third template argument is a vertex base class from which Triangulation_vertex_base_with_info_3 derives. It has the default value Triangulation_vertex_base_3<TriangulationTraits_3>.

### Is Model for the Concept

TriangulationVertexBase_3

### Inherits From

TriangulationVertexBase_3

### Types

typedef Info | Info;

### Access Functions

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