Definition

template<typename Key, typename PointPropertyMap, typename Base_distance>
class CGAL::Distance_adapter< Key, PointPropertyMap, Base_distance >

A class that uses a point property map to adapt a distance class to work on a key as point type. When using Search_traits_adapter<Key,PointPropertyMap,BaseTraits> in a nearest neighbor search algorithm, this class must be used as distance.

Template Parameters

Key	is a type that is associated to a point of type `Base_distance::Point_d`.
PointPropertyMap	is a model of `ReadablePropertyMap` with `Key` as key type and `Base_distance::Point_d` as value type.
Base_distance	is a model of either `GeneralDistance` or `OrthogonalDistance`.

Is Model Of:

GeneralDistance if Base_distance is a model of GeneralDistance

OrthogonalDistance if Base_distance is a model of OrthogonalDistance
