CGAL::Spatial_sort_traits_adapter_2< Base_traits, PointPropertyMap > Class Template Reference

#include <CGAL/Spatial_sort_traits_adapter_2.h>

Inherits from

Base_traits.

Definition

template<typename Base_traits, typename PointPropertyMap>
class CGAL::Spatial_sort_traits_adapter_2< Base_traits, PointPropertyMap >

Given a property map associating a key to a point, the class Spatial_sort_traits_adapter_2 induces a spatial reorder of the keys instead of the points, the comparisons being done on the associated points.

In other words, the traits provides to a spatial sort algorithm a point type which is a key, while the actual point type is Base_traits::Point_2.

Template Parameters

Base_traits	must be a model for SpatialSortingTraits_2.
PointPropertyMap	must be a model of ReadablePropertyMap with value type Base_traits::Point_2.

Is model of

SpatialSortingTraits_2

Examples

Spatial_sorting/sp_sort_using_property_map_2.cpp.

Types
typedef boost::property_traits< PointPropertyMap >::key_type	Point_2

Creation
	Spatial_sort_traits_adapter_2 (Base_traits base=Base_traits())
	Spatial_sort_traits_adapter_2 (const PointPropertyMap &ppmap, Base_traits base=Base_traits())

Operations
const PointPropertyMap &	point_property_map () const
	Returns a const reference to the point property map.
