type_index
// In header: <boost/type_index.hpp> typedef platform_specific type_index;
Depending on a compiler flags, optimal implementation of type_index will be used as a default boost::typeindex::type_index.
Could be a boost::typeindex::stl_type_index, boost::typeindex::ctti_type_index or user defined type_index class.
See boost::typeindex::type_index_facade for a full description of type_index functions.
