\cgalModels{SegmentDelaunayGraphVertexBase_2}

The class `Segment_Delaunay_graph_vertex_base_2` provides a model for the
`SegmentDelaunayGraphVertexBase_2` concept which is the vertex
base required by the `SegmentDelaunayGraphDataStructure_2`
concept.

\tparam St must be a model of the concept `SegmentDelaunayGraphStorageTraits_2`.
           This type must be template parameter used for `CGAL::Segment_Delaunay_graph_2`.

\tparam Vb is a vertex base class from which `Segment_Delaunay_graph_vertex_base_2` derives.
           It must be a model of the `TriangulationDSVertexBase_2` concept.
           It has the default value `CGAL::Triangulation_ds_vertex_base_2<>`.
