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>

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

  SDGPolicy;
typedef
CGAL::Segment_Delaunay_graph_adaptation_traits_2<SDG>

typedef CGAL::Voronoi_diagram_2<SDG,SDGAdaptTraits,SDGPolicy>                 
                  VD;  


Thanks,
