Inherits from

Base_traits.

Definition

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_traitsmust be a model for SpatialSortingTraits_2.
PointPropertyMapmust 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.
