#include <CGAL/HalfedgeDS_min_items.h>

Definition

The class HalfedgeDS_min_items is a model of the HalfedgeDSItems concept.

It defines types for vertices, halfedges, and faces that declare the minimal required incidences for a HalfedgeDS, which are the next() and the opposite() member function for halfedges.

Is Model Of:
HalfedgeDSItems

Example

The following example shows the canonical implementation of the CGAL::HalfedgeDS_min_items class. It uses the base classes for the item types that are provided in the library.

struct HalfedgeDS_min_items {
template < class Refs, class Traits>
struct Vertex_wrapper {
typedef CGAL::HalfedgeDS_vertex_min_base< Refs> Vertex;
};
template < class Refs, class Traits>
struct Halfedge_wrapper {
typedef CGAL::HalfedgeDS_halfedge_min_base< Refs> Halfedge;
};
template < class Refs, class Traits>
struct Face_wrapper {
typedef CGAL::HalfedgeDS_face_min_base< Refs> Face;
};
};
