Detailed Description

template<typename Geometry>
struct boost::geometry::geometry_id< Geometry >

Meta-function returning the id of a geometry type.

The meta-function geometry_id defines a numerical ID (based on boost::mpl::int_<...> ) for each geometry concept. A numerical ID is sometimes useful, and within Boost.Geometry it is used for the reverse_dispatch metafuntion.

Note

Used for e.g. reverse meta-function
