'''<indexterm><primary>boost</primary></indexterm><indexterm><primary>geometry</primary></indexterm><indexterm><primary>index</primary></indexterm><indexterm><primary>rtree</primary></indexterm>'''
The R-tree spatial index. 

[heading Description]
This is self-balancing spatial index capable to store various types of Values and balancing algorithms.

[heading Parameters]
The user must pass a type defining the Parameters which will be used in rtree creation process. This type is used e.g. to specify balancing algorithm with specific parameters like min and max number of elements in node.




Predefined algorithms with compile-time parameters are: 

* [^[link structboost_1_1geometry_1_1index_1_1linear boost::geometry::index::linear]], 
* [^[link structboost_1_1geometry_1_1index_1_1quadratic boost::geometry::index::quadratic]], 
* [^[link structboost_1_1geometry_1_1index_1_1rstar boost::geometry::index::rstar]].






Predefined algorithms with run-time parameters are: 

* [^[link classboost_1_1geometry_1_1index_1_1dynamic__linear boost::geometry::index::dynamic_linear]], 
* [^[link classboost_1_1geometry_1_1index_1_1dynamic__quadratic boost::geometry::index::dynamic_quadratic]], 
* [^[link classboost_1_1geometry_1_1index_1_1dynamic__rstar boost::geometry::index::dynamic_rstar]].



[heading IndexableGetter]
The object of IndexableGetter type translates from Value to Indexable each time r-tree requires it. This means that this operation is done for each Value access. Therefore the IndexableGetter should return the Indexable by a reference type. The Indexable should not be calculated since it could harm the performance. The default IndexableGetter can translate all types adapted to Point, Box or Segment concepts (called Indexables). Furthermore, it can handle [^`std::pair<Indexable, T>`], [^`boost::tuple<Indexable, ...>`] and [^`std::tuple<Indexable, ...>`] when possible. For example, for Value of type [^`std::pair<Box, int>`], the default IndexableGetter translates from [^`std::pair<Box, int> const&`] to [^`Box const&`].

[heading EqualTo]
The object of EqualTo type compares Values and returns [^`true`] if they are equal. It's similar to [^`std::equal_to<>`]. The default EqualTo returns the result of [^`boost::geometry::equals()`] for types adapted to some Geometry concept defined in Boost.Geometry and the result of [^`operator==`] for other types. Components of Pairs and Tuples are compared left-to-right.

[section query(Predicates const &, OutIter)]
'''<indexterm><primary>query</primary></indexterm>'''
Finds values meeting passed predicates e.g. nearest to some Point and/or intersecting some Box. 

[heading Description]
This query function performs spatial and k-nearest neighbor searches. It allows to pass a set of predicates. Values will be returned only if all predicates are met.

[*Spatial predicates]

Spatial predicates may be generated by one of the functions listed below: 

* [^[link group__predicates_1gac52a6557110425d4ece53fbd6f9ff866 boost::geometry::index::contains()]], 
* [^[link group__predicates_1ga02dbb7cca47de0b921ef96af464d9590 boost::geometry::index::covered_by()]], 
* [^[link group__predicates_1ga0e92e4a20dd19185584fe85847439108 boost::geometry::index::covers()]], 
* [^[link group__predicates_1ga0aa114ab16f40c8caeb3338adba5d6da boost::geometry::index::disjoint()]], 
* [^[link group__predicates_1ga78cb2ef221b951867c591ffb51b7d8c5 boost::geometry::index::intersects()]], 
* [^[link group__predicates_1ga4a6d33e6f61ad5bff3bdee50a972d54b boost::geometry::index::overlaps()]], 
* [^[link group__predicates_1gaabce901b82af2aab10ebbd0dda12f4d5 boost::geometry::index::within()]],


It is possible to negate spatial predicates: 

* [^`! `[link group__predicates_1gac52a6557110425d4ece53fbd6f9ff866 boost::geometry::index::contains()]], 
* [^`! `[link group__predicates_1ga02dbb7cca47de0b921ef96af464d9590 boost::geometry::index::covered_by()]], 
* [^`! `[link group__predicates_1ga0e92e4a20dd19185584fe85847439108 boost::geometry::index::covers()]],

* [^`! `[link group__predicates_1gaabce901b82af2aab10ebbd0dda12f4d5 boost::geometry::index::within()]]

[*Satisfies predicate]

This is a special kind of predicate which allows to pass a user-defined function or function object which checks if Value should be returned by the query. It's generated by: 

* [^[link group__predicates_1ga3213772dd3e54ad03340c2ca66b4f58c boost::geometry::index::satisfies()]].

[*Nearest predicate]

If the nearest predicate is passed a k-nearest neighbor search will be performed. This query will result in returning k values to the output iterator. Only one nearest predicate may be passed to the query. It may be generated by: 

* [^[link group__predicates_1ga8772d9d3e5b12b3292f7d94d47310e3e boost::geometry::index::nearest()]].

[*Connecting predicates]

Predicates may be passed together connected with [^`operator&&()`].[heading Synopsis]
