- With Boost.Bimap, you can build associative containers in which both types
- can be used as key. There is a library in Boost that already allows the creation
- of this kind of container: Boost.MultiIndex. It offers great flexibility
- and lets you construct almost any container that you could dream of. The
- framework is very clean. You might want to read this library's tutorial to
- learn about the power that has been achieved.
- </p>
- <p>
- But generality comes at a price: the interface that results might not be
- the best for every specialization. People may end up wrapping a B.MI container
- in its own class every time they want to use it as a bidirectional map. Boost.Bimap
- takes advantage of the narrower scope to produce a better interface for bidirectional
- maps <a href="#ftn.boost_bimap.bimap_and_boost.bimap_and_multiindex.f0" class="footnote" name="boost_bimap.bimap_and_boost.bimap_and_multiindex.f0"><sup class="footnote">[2]</sup></a>. There is no learning curve if you know how to use standard containers.
- Great effort was put into mapping the naming scheme of the STL to Boost.Bimap.
- The library is designed to match the common STL containers.
- </p>
- <p>
- Boost.MultiIndex is, in fact, the core of the bimap container.
- </p>
- <p>
- However, Boost.Bimap do not aim to tackle every problem with two indexed
- types. There exist some problems that are better modelled with Boost.MultiIndex.

- </p>
- <p>
- <span class="emphasis"><em>Store an ID and a name for an employee, with fast search on each

- </p>
- <p>
- This type of problem is better modelled as a database table, and <span class="bold"><strong>Boost.MultiIndex</strong></span> is the preferred choice. It is possible
