CGAL 5.1.2 - 2D Regularized Boolean Set-Operations
|
A face record in a Dcel data structure used by the General_polygon_set_2
and Polygon_set_2
template classes to represent the underlying internal Arrangement_2
data structure.
Access Functions | |
bool | contained () const |
returns true if the face is contained in the general-polygon set, and false otherwise. | |
bool | visited () |
returns true if the face has been visited, and false otherwise. More... | |
std::size_t | id () const |
returns an id associated to the face using set_id() ; If no call to set_id() was done or if reset_id() was called, the returned value is not specified and id_not_set() must return true . | |
bool | id_not_set () const |
returns true if set_id() was not called or if reset_id() was called, amd false otherwise. | |
Modifiers | |
void | set_contained (bool flag) |
marks the face as contained (if flag is true ), or as a hole (if it is false ). | |
void | reset_id () |
marks the face as visited (if flag is true ), or as not visited (if it is false ). More... | |
void | set_id (std::size_t i) |
sets the id associated to the face. More... | |
void GeneralPolygonSetDcelFace::reset_id | ( | ) |
marks the face as visited (if flag
is true
), or as not visited (if it is false
).
This is used internally by the some of the operations of the General_polygon_set_2
class that traverse the arrangement faces.
resets the id associated to the face.
void GeneralPolygonSetDcelFace::set_id | ( | std::size_t | i | ) |
sets the id associated to the face.
i should be different from the largest possible value that std::size_t
can store.
bool GeneralPolygonSetDcelFace::visited | ( | ) |
returns true
if the face has been visited, and false
otherwise.
This is used internally by the some of the operations of the General_polygon_set_2
class that traverse the arrangement faces.
