Detailed Description

template<typename Value, bool IsIndexable = is_indexable<Value>::value>
struct boost::geometry::index::detail::indexable< Value, IsIndexable >

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, ...>.

Template Parameters
ValueThe Value type which may be translated directly to the Indexable.
IsIndexableIf true, the const reference to Value is returned.

Parameters
vThe value.
