mrpt::utils::bimap< KEY, VALUE > Class Template Reference

Detailed Description

template<typename KEY, typename VALUE>
class mrpt::utils::bimap< KEY, VALUE >

A bidirectional version of std::map, declared as bimap<KEY,VALUE> and which actually contains two std::map's, one for keys and another for values.

To use this class, insert new pairs KEY<->VALUE with bimap::insert. Then, you can access the KEY->VALUE map with bimap::direct(), and the VALUE->KEY map with bimap::inverse(). The consistency of the two internal maps is assured at any time.

Note

This class can be accessed through iterators to the map KEY->VALUE only.

Both typenames KEY and VALUE must be suitable for being employed as keys in a std::map, i.e. they must be comparable through a "< operator".
