void GeneralPolygonSetDcelFace::assign

(

const Self &

other

)

assigns f with the contents of the other face.

bool GeneralPolygonSetDcelFace::contained

(

)

const

returns true if the face is contained in the general-polygon set, and false otherwise.

GeneralPolygonSetDcelFace::Gps_dcel_face

(

)

default constructor.

void GeneralPolygonSetDcelFace::set_contained

(

bool

flag

)

marks the face as contained (if flag is true), or as a hole (if it is false).

void GeneralPolygonSetDcelFace::set_visited

(

bool

flag

)

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.

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.
