The function object extracting Indexable from Value.
It translates Value object to Indexable object. The default version handles Values which are Indexables. This template is also specialized for std::pair<Indexable, T2>, boost::tuple<Indexable, ...> and std::tuple<Indexable, ...>.
| Value | The Value type which may be translated directly to the Indexable. |
| IsIndexable | If true, the const reference to Value is returned. |
| typedef Value const& boost::geometry::index::detail::indexable< Value, IsIndexable >::result_type |
The type of result returned by function object.
