## Definition

template<typename Info, typename Traits, typename Fb>
class CGAL::Triangulation_face_base_with_info_2< Info, Traits, Fb >

The class `Triangulation_face_base_with_info_2` is a model of the concept `TriangulationFaceBase_2` to be plugged into the triangulation data structure of a triangulation class.

It provides an easy way to add some user defined information in the faces of a triangulation.

Template Parameters

  Info | is the information the user would like to add to a face. It has to be `DefaultConstructible` and `Assignable`.
  Traits | is a geometric traits class and is actually not used in `Triangulation_face_base_with_info_2` .
  Fb | is a face base class from which `Triangulation_face_base_with_info_2` derives.

Is model of
  Because `Triangulation_face_base_with_info_2` derives from the class instantiating its third parameter, it will be a model of the same face base concept as its parameter: `TriangulationFaceBase_2`, `ConstrainedTriangulationFaceBase_2`, or `RegularTriangulationFaceBase_2`

## Types
typedef Info | Info

## Access Functions
const Info & | info () const
| Returns a const reference to the object of type `Info` stored in the face.
Info & | info ()
| Returns a reference to the object of type `Info` stored in the face.
