#include <CGAL/Voronoi_diagram_2.h>
The class Vertex is the Voronoi vertex class provided by the class Voronoi_diagram_2<DG,AT,AP> class.
Below we present its interface.

Access Methods | |
| Halfedge_handle | halfedge () |
Returns an incident halfedge that has v as its target. | |
| size_type | degree () |
Returns the in-degree of the vertex, i.e. the number of halfedges that have v as their target. | |
| Point_2 | point () |
| Returns the point represented by the vertex. | |
| Delaunay_face_handle | dual () |
| Returns a handle to the corresponding dual face in the Delaunay graph. | |
| Delaunay_vertex_handle | site (unsigned int i) |
| Returns a handle to the vertex in the Delaunay graph corresponding to the \( (i+1)\)-th generating site of the Voronoi vertex. More... | |
| Halfedge_around_vertex_circulator | incident_halfedges () |
Returns a bidirectional circulator that allows the traversal of the halfedges that have v as their target. More... | |
Predicate Methods | |
| bool | is_incident_edge (Halfedge_handle e) |
Returns true if the halfedge e is incident to v. | |
| bool | is_incident_face (Face_handle e) |
Returns true if the face f is incident to v. | |
| bool | is_valid () |
Returns true if the following conditions are met: the dual face is not an infinite face; all incident halfedges have the vertex as their target. | |
| typedef unspecified_type CGAL::Voronoi_diagram_2< DG, AT, AP >::Vertex::Delaunay_graph |
A type for the Delaunay graph.
It is a model of the DelaunayGraph_2 concept.
| typedef unspecified_type CGAL::Voronoi_diagram_2< DG, AT, AP >::Vertex::Halfedge_around_vertex_circulator |
A type for a bidirectional circulator that allows to traverse all incident halfedges, i.e., all halfedges that have the vertex as their target.
The value type of the circulator is CGAL::Voronoi_diagram_2<DG,AT,AP>::Halfedge and is convertible to Halfedge_handle.
| Halfedge_around_vertex_circulator CGAL::Voronoi_diagram_2< DG, AT, AP >::Vertex::incident_halfedges | ( | ) |
Returns a bidirectional circulator that allows the traversal of the halfedges that have v as their target.
Applying operator++ (resp. operator-) to this circulator returns the next incident halfedge in the counterclockwise (resp. clockwise) sense.
| Delaunay_vertex_handle CGAL::Voronoi_diagram_2< DG, AT, AP >::Vertex::site | ( | unsigned int | i | ) |
Returns a handle to the vertex in the Delaunay graph corresponding to the \( (i+1)\)-th generating site of the Voronoi vertex.
i must be smaller or equal to 2.
