## Definition

template<typename Graph>
class CGAL::Face_around_face_iterator< Graph >

A bidirectional iterator with value type `boost::graph_traits<Graph>::face_descriptor`.

It iterates over the same halfedges as the `Halfedge_around_face_iterator`, and provides the face descriptor associated to the opposite halfedge. The face descriptor may be the null face, and it may be several times the same face descriptor.

Template Parameters
