TriangulationDSVertexBase_2

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.

Types
typedef unspecified_type	Geom_traits
	A type for the geometric traits that defines the site.
typedef unspecified_type	Site_2
	A type for the site.
typedef unspecified_type	Storage_site_tag
	A type that indicates what kind of storage type to use.
typedef unspecified_type	Storage_site_2
	A type for the internal representation of sites.
typedef unspecified_type	Data_structure
	A type for the underlying data structure, to which the vertex belongs to.
typedef unspecified_type	Vertex_handle
	A type for the vertex handle of the segment Delaunay graph data structure.
typedef unspecified_type	Face_handle
	A type for the face handle of the segment Delaunay graph data structure.

Creation
In addition to the default and copy constructors and following constructors are required:
	SegmentDelaunayGraphVertexBase_2 (const Storage_site_2 &ss)
	Constructs a vertex associated with the site represented by the storage site ss.
	SegmentDelaunayGraphVertexBase_2 (const 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
const Storage_site_2 &	storage_site ()
	Returns the storage site representing the site.
Site_2	site ()
	Returns the site.
Face_handle	face ()
	Returns a handle to an incident face.

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

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

Member Typedef Documentation

Geom_traits

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.

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.

Storage_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.

Storage_site_tag

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.
