Item Classes

`#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;
};
};
