Detailed Description

template<class Traits_, class Arrangement_, class Event_, class Subcurve_>
class Arr_bounded_planar_construction_helper< Traits_, Arrangement_, Event_, Subcurve_ >

Definition of the Arr_bounded_planar_construction_helper class-template.

A helper class for the construction sweep-line visitor, suitable for an Arrangement_on_surface_2 instantiated with a topology-traits class for bounded curves in the plane.
