concept	SegmentDelaunayGraphDataStructure_2
	The concept SegmentDelaunayGraphDataStructure_2 refines the concept ApolloniusGraphDataStructure_2. In addition it provides two methods for the merging of two vertices joined by an edge of the data structure, and the splitting of a vertex into two. The method that merges two vertices, called join_vertices() identifies the two vertices and deletes their common two faces. The method that splits a vertex, called split_vertex() introduces a new vertex that shares an edge and two faces with the old vertex (see figure below). Notice that the join_vertices() and split_vertex() operations are complementary, in the sense that one reverses the action of the other. More...
concept	SegmentDelaunayGraphFaceBase_2
	The concept SegmentDelaunayGraphFaceBase_2 describes the requirements for the face base class of the SegmentDelaunayGraphDataStructure_2 concept. More...
concept	SegmentDelaunayGraphHierarchyVertexBase_2
	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 preceeding levels. Therefore, the concept SegmentDelaunayGraphHierarchyVertexBase_2 refines the concept SegmentDelaunayGraphVertexBase_2, by adding two vertex handles to the correponding vertices for the next and previous level graphs.

concept	SegmentDelaunayGraphSite_2
	The concept SegmentDelaunayGraphSite_2 provides the requirements for the sites of a segment Delaunay graph. More...
concept	SegmentDelaunayGraphStorageSite_2
	The concept SegmentDelaunayGraphStorageSite_2 provides the requirements for the storage sites of a segment Delaunay graph. The storage sites are sites that are used to store the information of a site in a more compact form (that uses less storage). This is achieved by storing handles to points instead of points. More...
concept	SegmentDelaunayGraphStorageTraits_2
	The concept SegmentDelaunayGraphStorageTraits_2 provides the requirements for the storage traits of a segment Delaunay graph. More...
