#### Boost.Array

Boost.Array arrays are adapted to the Boost.Geometry point concept

###### Description

A boost::array is (optionally) adapted to the Boost.Geometry point concept. It can therefore be used in all Boost.Geometry algorithms.

A boost::array can be the point type used by the models linestring, polygon, segment, box, and ring

###### Model of

Point Concept

###### Header

`#include <boost/geometry/geometries/adapted/boost_array.hpp>`

The standard header `boost/geometry.hpp` does not include this header.

###### Example

Shows how to use a Boost.Array using Boost.Geometry's distance, set and assign_values algorithms

    #include <iostream>

    #include <boost/geometry.hpp>
    #include <boost/geometry/geometries/linestring.hpp>
    #include <boost/geometry/geometries/adapted/boost_array.hpp>

    BOOST_GEOMETRY_REGISTER_BOOST_ARRAY_CS(cs::cartesian)

    int main()
    {
        boost::array<float, 2> a = { {1, 2} };
        boost::array<double, 2> b = { {2, 3} };
        std::cout << boost::geometry::distance(a, b) << std::endl;

        boost::geometry::set<0>(a, 1.1f);
        boost::geometry::set<1>(a, 2.2f);
        std::cout << boost::geometry::distance(a, b) << std::endl;

        boost::geometry::assign_values(b, 2.2, 3.3);
        std::cout << boost::geometry::distance(a, b) << std::endl;

        boost::geometry::model::linestring<boost::array<double, 2> > line;
        line.push_back(b);

        return 0;
    }

Output:
