SegmentVoronoiDiagramVertexBase_2

Definition

The concept SegmentVoronoiDiagramVertexBase_2 describes the requirements for the vertex base class of the SegmentVoronoiDiagramDataStructure_2 concept. A vertex stores a site of the segment Voronoi diagram and provides access to one of its incident faces through a Face_handle.

Types

SegmentVoronoiDiagramVertexBase_2::Geom_traits
	A type for the geometric traits that defines the site. Precondition: The type Geom_traits must define the type Site_2.
SegmentVoronoiDiagramVertexBase_2::Site_2
	A type for the site. This type must coincide with the type Geom_traits::Site_2.
SegmentVoronoiDiagramVertexBase_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.
SegmentVoronoiDiagramVertexBase_2::Storage_site_2
	A type for the internal representation of sites. This type must satisfy the requirements of the concept SegmentVoronoiDiagramStorageSite_2.
SegmentVoronoiDiagramVertexBase_2::Data_structure
	A type for the underlying data structure, to which the vertex belongs to.
SegmentVoronoiDiagramVertexBase_2::Vertex_handle
	A type for the vertex handle of the segment Voronoi diagram data structure.
SegmentVoronoiDiagramVertexBase_2::Face_handle
	A type for the face handle of the segment Voronoi diagram data structure.

Creation

In addition to the default and copy constructors and following constructors are required:

SegmentVoronoiDiagramVertexBase_2 v ( Storage_site_2 ss);
Constructs a vertex associated with the site represented by the storage site ss.

SegmentVoronoiDiagramVertexBase_2 v ( Storage_site_2 ss, Face_handle f);
Constructs a vertex associated with the site represented by the storage site ss, and pointing to the face associated with the face handle f.

Access Functions

Storage_site_2	v.storage_site ()	Returns the storage site representing the site.
Site_2	v.site ()	Returns the site.
Face_handle	v.face ()	Returns a handle to an incident face.

Setting

void	v.set_site ( Storage_site_2 ss)
		Sets the storage site.
void	v.set_face ( Face_handle f)
		Sets the incident face.

Checking

bool	v.is_valid ( bool verbose, int level)
		Performs any required tests on a vertex.
