The function object extracting Indexable from Value.
It translates Value object to Indexable object. By default, it can handle Values which are Indexables, std::pair<Indexable, T2>, boost::tuple<Indexable, ...> and std::tuple<Indexable, ...> if STD tuples and variadic templates are supported.
Value | The Value type which may be translated directly to the Indexable. |
result_type boost::geometry::index::indexable< Value >::operator() | ( | Value const & | v | ) | const [inline] |
Return indexable extracted from the value.
v | The value. |
Reimplemented from boost::geometry::index::detail::indexable< Value >.
