| </h6> |
| <p> |
| The macro BOOST_GEOMETRY_REGISTER_RING_TEMPLATED registers a templated |
| ring 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 ring are registered, regardless of their |
| point type. |
