Dear CGAL community,

I am using the following setup to generate a Voronoi diagram:

...
typedef CGAL::Delaunay_triangulation_2< K, Tds> Delaunay;
typedef CGAL::Delaunay_triangulation_adaptation_traits_2< Delaunay> AT;
typedef CGAL::Delaunay_triangulation_caching_degeneracy_removal_policy_2<
   Delaunay> AP;
typedef CGAL::Voronoi_diagram_2< Delaunay, AT, AP> VD;

which successfully removes degenerate edges from the Voronoi.  In part
for my code I iterate over all Delaunay edges and call

voronoi.dual(delaunayEdge)

but this causes assertions because some of the edges are rejected.  Is
there a way to check if the Delaunay edge corresponds to a rejected
dual?  Or with this setup am I only 'allowed' to go from Voronoi edges
to Delaunay edges and not the other way around?

At the moment I'm using:

if(!voronoi.edge_rejector()(delaunay, delaunayEdge))

but it seems quite clear from the source that edge_rejector(...) is
not API facing code.

Many thanks,
-Martin
