Awesome. It looks like this will do. Thanks Sebastien.

Using a Face_handle f, you can get one border halfedge using
Halfedge_handle h = f->halfedge() and you can circulate around
the face iteratively using h=h->next() while h!=f->halfedge();

Hello all,

I'm trying to get all the (half)edges around a voronoi site of CGAL's
[Voronoi_diagram_2](http://doc.cgal.org/latest/Voronoi_diagram_2/classCGAL_1_1Voronoi__diagram__2.html)

How can we circulate around a Voronoi_2 site?

I know we have a Site iterator, but what functions does Site_2 provide?

If I change to its delaunay dual, is there a method?

One workaround I can think of is by circulating around the faces and
retrieving the edge that doesn't have the vertex.

I could traverse all the halfedges and store them by site on map. But I
would lose the ordering.

I'm pretty sure there's a method but I can't find it.
