CGAL 5.5.2  CGAL and the Boost Graph Library

#include <CGAL/boost/graph/iterator.h>
A bidirectional circulator with value type boost::graph_traits<Graph>::halfedge_descriptor
over all halfedges having the same vertex as target.
Let h
be a halfedge of graph g
. For a Halfedge_around_target_circulator
havc
with h = *havc;
the following holds: opposite(next(h,g),g) == *++havc
.
Graph  must be a model of the concept HalfedgeGraph
