C++11 array containers are adapted to the Boost.Geometry point concept

A C++11 std::array is (optionally) adapted to the Boost.Geometry point concept. It can therefore be used in all Boost.Geometry algorithms.

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

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

The standard header `boost/geometry.hpp`

does not include this header.

Shows how to use a C++11 std::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/std_array.hpp> BOOST_GEOMETRY_REGISTER_STD_ARRAY_CS(cs::cartesian) int main() { std::array<float, 2> a = { {1, 2} }; std::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<std::array<double, 2> > line; line.push_back(b); return 0; }
