BOOST_GEOMETRY_REGISTER_MULTI_POINT_TEMPLATED

Macro to register a templated multi_point.

Description

The macro BOOST_GEOMETRY_REGISTER_MULTI_POINT_TEMPLATED registers a templated multi_point such that it is recognized by Boost.Geometry and that Boost.Geometry functionality can used with the specified type. The type must have one template parameter, which should be a point type, and should not be specified. Boost.Geometry takes care of inserting the template parameter. Hence all types of this templated multi_point are registered, regardless of their point type.

Synopsis

#define BOOST_GEOMETRY_REGISTER_MULTI_POINT_TEMPLATED(MultiPoint)

Parameters

Name

Description

MultiPoint

multi_point (without template parameters) type to be registered

Header

#include <boost/geometry/multi/geometries/register/multi_point.hpp>

Example

Show the use of the macro BOOST_GEOMETRY_REGISTER_MULTI_POINT_TEMPLATED

#include <iostream>
#include <boost/geometry.hpp>
#include <boost/geometry/geometries/adapted/boost_tuple.hpp>
#include <boost/geometry/multi/geometries/register/multi_point.hpp>


BOOST_GEOMETRY_REGISTER_MULTI_POINT_TEMPLATED(std::deque)

BOOST_GEOMETRY_REGISTER_BOOST_TUPLE_CS(cs::cartesian)

int main()
{
    // Normal usage of std::
    std::deque<boost::tuple<float, float> > multi_point;
    multi_point.push_back(boost::tuple<float, float>(1, 1));
    multi_point.push_back(boost::tuple<float, float>(3, 2));
    
    // Usage of Boost.Geometry
    std::cout << "WKT: "  << boost::geometry::wkt(multi_point) << std::endl;
    
    return 0;
}

Output:

WKT: MULTIPOINT((1 1),(3 2))
