## CGAL::Topological_map<Dcel>::Vertex

### Definition

An object v of the class Topological_map<Dcel>::Vertex is a vertex of a topological map.

### Inherits From

Dcel::Vertex

### Creation

Topological_map<Dcel>::Vertex v;
| default constructor.

### Access Functions

Halfedge_around_vertex_circulator
| v.incident_halfedges ()
|  | returns a circulator that allows to traverse the halfedges that have v as their target. The edges are traversed around v in an order opposite that of the Ccb_halfedge_circulator. This circulator can also be used to access incident faces and vertices.

### Predicates

bool | v.is_incident_edge ( Halfedge_const_handle e)
|  | returns true if e is incident to v (i.e., if v is the source or the target of e).
bool | v.is_incident_face ( Face_const_handle f)
|  | returns true if f is incident to v.

### Query Functions

unsigned int | v.degree () | returns the degree of v i.e., the number of outgoing halfedges.
