##### BOOST_GEOMETRY_REGISTER_MULTI_LINESTRING

Macro to register a multi_linestring.

###### Description

The macro BOOST_GEOMETRY_REGISTER_MULTI_LINESTRING registers a multi_linestring such that it is recognized by Boost.Geometry and that Boost.Geometry functionality can used with the specified type. The multi_linestring may contain template parameters, which must be specified then.

###### Synopsis

    #define BOOST_GEOMETRY_REGISTER_MULTI_LINESTRING(MultiLineString)

###### Parameters

Name | Description
--- | ---
MultiLineString | multi_linestring type to be registered

###### Header

`#include <boost/geometry/geometries/register/multi_linestring.hpp>`

###### Example

Show the use of the macro BOOST_GEOMETRY_REGISTER_MULTI_LINESTRING

    #include <iostream>

    #include <boost/geometry.hpp>
    #include <boost/geometry/geometries/linestring.hpp>
    #include <boost/geometry/geometries/adapted/boost_tuple.hpp>
    #include <boost/geometry/geometries/register/multi_linestring.hpp>

    typedef boost::geometry::model::linestring
        <
            boost::tuple<float, float>
        > linestring_type;

    BOOST_GEOMETRY_REGISTER_BOOST_TUPLE_CS(cs::cartesian)
    BOOST_GEOMETRY_REGISTER_MULTI_LINESTRING(std::deque<linestring_type>)

    int main()
    {
        // Normal usage of std::
        std::deque<linestring_type> lines(2);
        boost::geometry::read_wkt("LINESTRING(0 0,1 1)", lines[0]);
        boost::geometry::read_wkt("LINESTRING(2 2,3 3)", lines[1]);

        // Usage of Boost.Geometry
        std::cout << "LENGTH: "  << boost::geometry::length(lines) << std::endl;

        return 0;
    }

Output:

    LENGTH: 2.82843
