SegmentVoronoiDiagramHierarchyVertexBase_2
Definition
The vertex of a segment Voronoi diagram
included in a segment Voronoi diagram hierarchy has to provide
some pointers to the corresponding vertices in the
graphs of the next and preceeding levels.
Therefore, the concept SegmentVoronoiDiagramHierarchyVertexBase_2
refines the concept SegmentVoronoiDiagramVertexBase_2, by
adding two vertex handles to the correponding vertices for the
next and previous level graphs.

SegmentVoronoiDiagramVertexBase_2 concept.
Operations
|
Vertex_handle
|
v.up ()
|
Returns a handle to the corresponding
vertex of the next level segment Voronoi diagram. If such a vertex
does not exist Vertex_handle() is returned.
|
|
Vertex_handle
|
v.down ()
|
Returns a handle to the corresponding
vertex of the previous level segment Voronoi diagram. If such a
vertex does not exist Vertex_handle() is returned.
|
|
void
|
v.set_up ( Vertex_handle u)
|
| |
Sets the handle for the
vertex of the next level segment Voronoi diagram.
|
|
void
|
v.set_down ( Vertex_handle d)
|
| |
Sets the handle for the
vertex of the previous level segment Voronoi diagram;
