I didn't follow everything but it seems too complicated if you just wanted to add data to a vertex. You don't need to derive anything. I did something similar:
typedef CGAL::Triangulation_vertex_base_with_info_2<int, Kernel> Vb;
typedef CGAL::Triangulation_face_base_2<Kernel> Fb;
typedef CGAL::Triangulation_data_structure_2<Vb,Fb> Tds;
typedef CGAL::Delaunay_triangulation_2<Kernel, Tds> DT;
typedef CGAL::Delaunay_triangulation_adaptation_traits_2<DT> AT;
typedef CGAL::Delaunay_triangulation_caching_degeneracy_removal_policy_2<DT> AP;
typedef CGAL::Voronoi_diagram_2<DT, AT, AP> VD;

Maybe you should try first, just to use cgal basic vertex class with info, and just add an integer. If it works, in the worst case you could hold a pointer to your data there.

Subject: [cgal-discuss] Trying to add info to a vertex in a segment Delaunay graph fails compilation
Hello,
I am trying to add information to a vertex in a SDG. For that matter, I took
some code from the SDG demo and tryed to incorporate it, but obviously I am
doing something wrong, because it doesn't compile. The code is:
template < class Vbb, class Info_ >
class Segment_Delaunay_graph_vertex_base_with_info_2
: public Vbb
{
public:
// TYPES
//------
typedef Vbb Base;
typedef Info_ Info;
typedef typename Base::Storage_traits Storage_traits;
typedef typename Base::Geom_traits Geom_traits;
typedef typename Base::Site_2 Site_2;
typedef typename Base::Storage_site_2 Storage_site_2;
typedef typename Base::Data_structure Data_structure;
typedef typename Data_structure::Face_handle Face_handle;
typedef typename Data_structure::Vertex_handle Vertex_handle;
template < typename DS2 >
struct Rebind_TDS {
typedef typename Vbb::template Rebind_TDS<DS2>::Other Vb2;
typedef Segment_Delaunay_graph_vertex_base_with_info_2<Vb2,Info> Other;
};
Segment_Delaunay_graph_vertex_base_with_info_2 () : Vbb(), info_() {}
Segment_Delaunay_graph_vertex_base_with_info_2(const Storage_site_2& ss,
Face_handle f)
: Vbb(ss, f), info_() {}
void set_info(const Info& info) { info_ = info; }
const Info& info() const { return info_; }
private:
Info info_;
};
struct SiteInfo{
Number v;
SiteInfo(){}
};
typedef CGAL::Segment_Delaunay_graph_traits_without_intersections_2<Kernel>
SDGTraits;
typedef CGAL::Segment_Delaunay_graph_storage_traits_2<SDGTraits>
ST;
typedef CGAL::Segment_Delaunay_graph_vertex_base_2<ST> Vb;
typedef CGAL::Segment_Delaunay_graph_vertex_base_with_info_2<Vb,SiteInfo> Vbi;
typedef CGAL::Triangulation_face_base_2<SDGTraits> Fb;
typedef CGAL::Triangulation_data_structure_2<Vbi,Fb> DS;
typedef CGAL::Segment_Delaunay_graph_2<ST,DS> SDG;
typedef SDG::Site_2 SDGSite;
typedef
CGAL::Segment_Delaunay_graph_degeneracy_removal_policy_2<SDG> SDGPolicy;
typedef
CGAL::Segment_Delaunay_graph_adaptation_traits_2<SDG> SDGAdaptTraits;
typedef CGAL::Voronoi_diagram_2<SDG,SDGAdaptTraits,SDGPolicy> VD;
Thanks,
Amir.
