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.

Creation
	Orthogonal_incremental_neighbor_search (SpatialTree &tree, Query_item query, FT eps=FT(0.0), bool search_nearest=true, OrthogonalDistance d=OrthogonalDistance())
	Constructor for incremental neighbor searching of the query item query in the points stored tree using a distance d and approximation factor eps.

iterator	end () const
	Returns the appropriate past-the-end const iterator.
std::ostream &	statistics (std::ostream &s) const
	Inserts statistics of the search process into the output stream s.
