Access Methods
Halfedge_handle	halfedge ()
	Returns an incident halfedge on the boundary of f.
Ccb_halfedge_circulator	ccb ()
	Returns a bidirectional circulator for traversing the halfedges on the boundary of f. More...
Delaunay_vertex_handle	dual ()
	Returns a handle to the corresponding dual vertex in the Delaunay graph.

Predicate Methods
bool	is_unbounded ()
	Returns true iff the face is an unbounded face in the Voronoi diagram.
bool	is_halfedge_on_ccb (Halfedge e)
	Returns true iff e is a halfedge of the boundary of f.
bool	is_valid ()
	Returns true iff the following conditions are met: the face is not rejected by the chosen adaptation policy; all its adjacent halfedges do not have zero length; all its adjacent halfedges return the face as their adjacent face.

Member Typedef Documentation

template<typename DG , typename AT , typename AP >

typedef unspecified_type CGAL::Voronoi_diagram_2< DG, AT, AP >::Face::Ccb_halfedge_circulator

A type for a bidirectional circulator over the halfedges on the boundary of the face.

The value type of the circulator is CGAL::Voronoi_diagram_2<DG,AT,AP>::Halfedge, and is convertible to Halfedge_handle.

template<typename DG , typename AT , typename AP >

typedef unspecified_type CGAL::Voronoi_diagram_2< DG, AT, AP >::Face::Delaunay_graph

A type for the Delaunay graph.

It is a model of the DelaunayGraph_2 concept.

Ccb_halfedge_circulator CGAL::Voronoi_diagram_2< DG, AT, AP >::Face::ccb

(

)

Returns a bidirectional circulator for traversing the halfedges on the boundary of f.

The halfedges are traversed in counterclockwise order.
