## CGAL::HalfedgeDS_halfedge_base<Refs>

### Definition

The class HalfedgeDS_halfedge_base<Refs> is a model of the HalfedgeDSHalfedge concept. Refs is an instantiation of a HalfedgeDS. The full declaration states four template parameters:

| template < | class Refs,
|  | class Tag_prev | = CGAL::Tag_true,
|  | class Tag_vertex | = CGAL::Tag_true,
|  | class Tag_face | = CGAL::Tag_true>
| class HalfedgeDS_halfedge_base;

If Tag_prev CGAL::Tag_true a reference to the previous halfedge is supported.

If Tag_vertex CGAL::Tag_true an incident vertex is supported.

If Tag_face CGAL::Tag_true an incident face is supported.

In all cases, a reference to the next halfedge and to the opposite halfedge is supported.
