SegmentDelaunayGraphVertexBase_2

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.

Types

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.

SegmentDelaunayGraphVertexBase_2::Site_2

A type for the site. This type must coincide with the type Geom_traits::Site_2.

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.

SegmentDelaunayGraphVertexBase_2::Storage_site_2

A type for the internal representation of sites. This type must satisfy the requirements of the concept SegmentDelaunayGraphStorageSite_2.

SegmentDelaunayGraphVertexBase_2::Data_structure

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

SegmentDelaunayGraphVertexBase_2::Vertex_handle

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

SegmentDelaunayGraphVertexBase_2::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 v ( Storage_site_2 ss);
	Constructs a vertex associated with the site represented by the storage site ss.
SegmentDelaunayGraphVertexBase_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) const
		Performs any required tests on a vertex.
