Definition

Types

typedef unspecified_type Geom_traits
 A type for the geometric traits that defines the site. More...
 
typedef unspecified_type Site_2
 A type for the site. More...
 
typedef unspecified_type Storage_site_tag
 A type that indicates what kind of storage type to use. More...
 
typedef unspecified_type Storage_site_2
 A type for the internal representation of sites. More...
 
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 (Storage_site_2 ss)
 Constructs a vertex associated with the site represented by the storage site ss.
 
 SegmentDelaunayGraphVertexBase_2 (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 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 (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

A type for the geometric traits that defines the site.

Precondition
The type Geom_traits must define the type Site_2.

A type for the site.

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

A type for the internal representation of sites.

This type must satisfy the requirements of the concept SegmentDelaunayGraphStorageSite_2.

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

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