'''<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]
An object of IndexableGetter type translates from Value to Indexable each time r-tree requires it. This operation is done for each Value access. The Indexable should not be calculated each time 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>`], [^`std::tuple<Indexable, ...>`] and [^`boost::tuple<Indexable, ...>`]. 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.

Remove a range of values from the container. 

[heading Description]
In contrast to the [^`std::set`] or [^`std::map erase()`] method it doesn't take iterators pointing to values stored in this container. It removes values equal to these passed as a range.

[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_1gaff057c9f612ef416fd834e4d59eb26e1 boost::geometry::index::contains()]], 
* [^[link group__predicates_1ga33e1bf84e5e3658fe19b19f6331314b3 boost::geometry::index::covered_by()]], 
* [^[link group__predicates_1ga546e417153441edbeeb55c50234bbeea boost::geometry::index::covers()]], 
* [^[link group__predicates_1gac4f2328326b16c98736a6dbb70948fba boost::geometry::index::disjoint()]], 
* [^[link group__predicates_1ga2e4da4b87ceea63756ec854aa265647c boost::geometry::index::intersects()]], 
* [^[link group__predicates_1gac94f965fd8d5b2200cb2493b9f1968ee boost::geometry::index::overlaps()]], 
* [^[link group__predicates_1ga2aa3520641e62522877d0e7dc9d4bf0d boost::geometry::index::within()]],


It is possible to negate spatial predicates: 

* [^`! `[link group__predicates_1gaff057c9f612ef416fd834e4d59eb26e1 boost::geometry::index::contains()]], 
* [^`! `[link group__predicates_1ga33e1bf84e5e3658fe19b19f6331314b3 boost::geometry::index::covered_by()]], 
* [^`! `[link group__predicates_1ga546e417153441edbeeb55c50234bbeea boost::geometry::index::covers()]], 
* [^`! `[link group__predicates_1gac4f2328326b16c98736a6dbb70948fba boost::geometry::index::disjoint()]], 
* [^`! `[link group__predicates_1ga2e4da4b87ceea63756ec854aa265647c boost::geometry::index::intersects()]], 
* [^`! `[link group__predicates_1gac94f965fd8d5b2200cb2493b9f1968ee boost::geometry::index::overlaps()]], 
* [^`! `[link group__predicates_1ga2aa3520641e62522877d0e7dc9d4bf0d 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_1gaf23b2a001cdc392f58c22f64d96aa97b 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_1ga8b4b9bdfa5e666c7e77b7ba5d6249d9e boost::geometry::index::nearest()]].

[*Connecting predicates]

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

[warning Only one [^[link group__predicates_1ga8b4b9bdfa5e666c7e77b7ba5d6249d9e nearest()]] predicate may be passed to the query. Passing more of them results in compile-time error.]
