`#include <CGAL/Spatial_sort_traits_adapter_3.h>`

## Inherits from

Base_traits.

## Definition

template<typename Base_traits, typename PointPropertyMap>
class CGAL::Spatial_sort_traits_adapter_3< Base_traits, PointPropertyMap >

Given a property map associating a key to a point, the class `Spatial_sort_traits_adapter_3` 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_3`.

Template Parameters

  Base_traits | must be a model for `SpatialSortingTraits_3`.
  PointPropertyMap | must be a model of `ReadablePropertyMap` with value type `Base_traits::Point_3`.

Is Model Of:
  `SpatialSortingTraits_3`

Examples
  Spatial_sorting/sp_sort_using_property_map_3.cpp.

## Types
typedef boost::property_traits< PointPropertyMap >::key_type | Point_3

## Creation
| Spatial_sort_traits_adapter_3 (Base_traits base=Base_traits())
| Spatial_sort_traits_adapter_3 (const PointPropertyMap &ppmap, Base_traits base=Base_traits())

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