## CGAL::Triangulation_cell_base_with_info_3<Info, TriangulationTraits_3, TriangulationCellBase_3>

### Definition

The class Triangulation_cell_base_with_info_3 is a model of the concept TriangulationCellBase_3, the base cell of a 3D-triangulation. It provides an easy way to add some user defined information in cells. Note that input/output operators discard this additional information.

#include <CGAL/Triangulation_cell_base_with_info_3.h>

### Parameters

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

The second template argument is the geometric traits class TriangulationTraits_3. It is actually not used by this class.

The third template argument is a cell base class from which Triangulation_cell_base_with_info_3 derives. It has the default value Triangulation_cell_base_3<TriangulationTraits_3>.

### Is Model for the Concept

TriangulationCellBase_3

### Inherits From

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