SegmentDelaunayGraphHierarchyVertexBase_2 Concept Reference

Definition

The vertex of a segment Delaunay graph included in a segment Delaunay graph hierarchy has to provide some pointers to the corresponding vertices in the graphs of the next and preceding levels. Therefore, the concept SegmentDelaunayGraphHierarchyVertexBase_2 refines the concept SegmentDelaunayGraphVertexBase_2, by adding two vertex handles to the corresponding vertices for the next and previous level graphs.

Member Function Documentation

down()

Vertex_handle SegmentDelaunayGraphHierarchyVertexBase_2::down

(

)

Returns a handle to the corresponding vertex of the previous level segment Delaunay graph.

If such a vertex does not exist Vertex_handle() is returned.

up()

Vertex_handle SegmentDelaunayGraphHierarchyVertexBase_2::up

(

)

Returns a handle to the corresponding vertex of the next level segment Delaunay graph.

If such a vertex does not exist Vertex_handle() is returned.
