#include <CGAL/Incremental_neighbor_search.h>

Definition

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

The tree may have extended or unextended nodes.

Template Parameters

Traits	must be a model of the concept `SearchTraits`, for example `Search_traits_2<Simple_cartesian<double> >`.
GeneralDistance	must be a model of the concept `GeneralDistance`. 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_false, Tag_false>`. The third template argument `Tag_false` makes that the tree is built with unextended nodes.

Types
typedef Traits::Point_d	Point_d
	Point type.

typedef Traits::NT	NT
	Number type.

typedef GeneralDistance	Distance
	Distance type.

typedef std::pair< Point_d, NT >	Point_with_transformed_distance
	Pair of point and transformed distance.

typedef unspecified_type	iterator
	const input iterator with value type `Point_with_transformed_distance` for enumerating approximate neighbors.

GeneralDistance::Query_item	Query_item
	Query item type.

SpatialTree	Tree
	The tree type.

Creation
	Incremental_neighbor_search (Tree &tree, QueryItem q, NT eps=NT(0.0), bool search_nearest=true, GeneralDistance d=GeneralDistance())
	Constructor for incremental neighbor searching of the query item `q` in the points stored `tree` using a distance `d` and approximation factor `eps`.

Operations
iterator	begin () const
	Returns a const iterator to the approximate nearest or furthest neighbor.

iterator	end () const
	Returns the appropriate past-the-end const iterator.

std::ostream &	statistics (std::ostream &s)
	Inserts statistics of the search process into the output stream `s`.
