bool
|
f.is_fictitious ()
|
returns whether this is the fictitious face, which contain the entire
arrangement (and has not outer CCB).
|
|
|
bool
|
f.is_unbounded ()
|
returns whether the face is unbounded.
|
|
|
Ccb_halfedge_circulator
|
f.outer_ccb ()
|
returns a circulator that allows going over the outer boundary of
f. The edges along the CCB are traversed in a counterclockwise
direction.
| Precondition: | f is not a fictitious face. |
|
|
|
Hole_iterator
|
f.holes_begin ()
|
returns an iterator for traversing all the holes (inner CCBs) of
f.
|
|
Hole_iterator
|
f.holes_end ()
|
returns a past-the-end iterator for the holes of f.
|
|
|
Isolated_vertex_iterator
|
f.isolated_vertices_begin ()
|
returns an iterator for traversing all the isolated vertices
contained in the interior of f.
|
|
Isolated_vertex_iterator
|
f.isolated_vertices_end ()
|
returns a past-the-end iterator for the isolated vertices
contained inside f.
