#include <Concepts/AosBasicTopologyTraits.h>

Definition

The concept AosBasicTopologyTraits defines the minimal functionality needed for a model of a topology traits, which can substitutes the TopolTraits template parameters when the class template Arrangement_on_surface_2<GeomTraits, TopolTraits> is instantiated. In particular. a model of this concept holds the Dcel data structure used to represent the arrangement cells (i.e., vertices, edges, and facets) and the incident relations between them.

Has models
: CGAL::Arr_spherical_topology_traits_2<GeometryTraits_2, Dcel>

Types
typedef unspecified_type	Point_2
	models the concept `AosTraits::Point_2`.

typedef unspecified_type	X_monotone_curve_2

Access Functions
const Dcel &	dcel () const
	obtains the DCEL (const version).

Dcel &	dcel ()
	obtains the DCEL (non-const version).
