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. |
result_type boost::geometry::index::detail::indexable< Value, IsIndexable >::operator() | ( | Value const & | v | ) | const [inline] |
Return indexable extracted from the value.
v | The value. |
Reimplemented in boost::geometry::index::indexable< Value >.
