CGAL::Orthogonal_incremental_neighbor_search< Traits, OrthogonalDistance, Splitter, SpatialTree > Class Template Reference

#include <CGAL/Orthogonal_incremental_neighbor_search.h>

Definition

template<typename Traits, typename OrthogonalDistance, typename Splitter, typename SpatialTree>
class CGAL::Orthogonal_incremental_neighbor_search< Traits, OrthogonalDistance, Splitter, SpatialTree >

The class Orthogonal_incremental_neighbor_search implements incremental nearest and furthest neighbor searching on a tree.

Template Parameters

Traits	must be a model of the concept SearchTraits, for example Search_traits_2<Simple_cartesian<double> >.
OrthogonalDistance	must be a model of the concept OrthogonalDistance. If Traits is Search_traits_adapter<Key,PointPropertyMap,BaseTraits> the default type is Distance_adapter<Key,PointPropertyMap,Euclidean_distance<BaseTraits> >, and Euclidean_distance<Traits> otherwise.
Splitter	must be a model of the concept Splitter. The default type is Sliding_midpoint<Traits>.
SpatialTree	must be a model of the concept SpatialTree. The default type is Kd_tree<Traits, Splitter, Tag_true, Tag_false>. The third template argument must be Tag_true because orthogonal search needs extended kd tree nodes.
