SegmentDelaunayGraphVertexBase_2 Concept Reference

Definition

The concept SegmentDelaunayGraphVertexBase_2 describes the requirements for the vertex base class of the SegmentDelaunayGraphDataStructure_2 concept. A vertex stores a site of the segment Delaunay graph and provides access to one of its incident faces through a Face_handle.

Member Typedef Documentation

typedef unspecified_type SegmentDelaunayGraphVertexBase_2::Data_structure

A type for the underlying data structure, to which the vertex belongs to.

typedef unspecified_type SegmentDelaunayGraphVertexBase_2::Face_handle

A type for the face handle of the segment Delaunay graph data structure.

typedef unspecified_type SegmentDelaunayGraphVertexBase_2::Geom_traits

A type for the geometric traits that defines the site.

Precondition

The type Geom_traits must define the type Site_2.

typedef unspecified_type SegmentDelaunayGraphVertexBase_2::Site_2

A type for the site.

This type must coincide with the type Geom_traits::Site_2.

typedef unspecified_type SegmentDelaunayGraphVertexBase_2::Storage_site_2

A type for the internal representation of sites.

This type must satisfy the requirements of the concept SegmentDelaunayGraphStorageSite_2.

typedef unspecified_type SegmentDelaunayGraphVertexBase_2::Storage_site_tag

A type that indicates what kind of storage type to use.

Storage_site_tag must either be CGAL::Tag_true or CGAL::Tag_false.

typedef unspecified_type SegmentDelaunayGraphVertexBase_2::Vertex_handle

A type for the vertex handle of the segment Delaunay graph data structure.
