#include <CGAL/HalfedgeDS_items_2.h>
The class HalfedgeDS_items_2 is a model of the HalfedgeDSItems concept.
It uses the default types for vertices, halfedges, and faces that declare all incidences supported by a HalfedgeDS. The vertex also contains a point of type Traits::Point_2, where Traits is the template argument of the corresponding HalfedgeDS.

The following example shows the canonical implementation of the HalfedgeDS_items_2 class. It uses the base classes for the item types that are provided in the library.
The following example shows a class definition for a new items class derived from the HalfedgeDS_items_2 class. It replaces the Face_wrapper with a new definition of a face that contains a member variable for color. The new face makes use of the face base class provided in the library.
