Arr_face_base.
An instance of this template serves as a basis type for any face record of the Dcel class used by instances of the General_polygon_set_2 and General_polygon_with_holes_2 class templates.
The Point_2 and the X_monotone_curve_2 template parameters are the types of points and \( x\)-monotone curves associated with the vertices and the halfedges, respectively.
You need to extend this template with auxiliary data only if you intend to obtain the underlying arrangement of the general polygon set and process it further.
