Though: for unordered sets, no guarantee is made about the order in which elements They were arranged in the views of the container. Retrieving an archived bimap restores not only the elements, but also the order The same happens when `BOOST_MULTI_INDEX_DISABLE_SERIALIZATION` is The macro `BOOST_BIMAP_DISABLE_SERIALIZATION` disables serialization in *both* [warning Boost.Bimap and Boost.MultiIndex share a lot of serialization code. If not used, however, serialization support canīe disabled by globally defining the macro BOOST_BIMAP_DISABLE_SERIALIZATION.ĭisabling serialization for Boost.MultiIndex can yield a small improvement inīuild times, and may be necessary in those defective compilers that fail toĬorrectly process Boost.Serialization headers. Include any header from Boost.Serialization, apart from those declaring the type Serialization capabilities are automatically provided by just linking with theĪppropriate Boost.Serialization library module: it is not necessary to explicitly Not differ from that of any other serializable type.

This problem is better modelled as a collection of relations, and ['Store the names of couples and be able to get the name of a person's This type of problem is better modelled as a database table, and There exist some problems that are better modelled with Boost.MultiIndex. However, Boost.Bimap do not aim to tackle every problem with two indexed The library is designed to match the common STL containers.īoost.MultiIndex is, in fact, the core of the bimap container. Great effort was put into mapping the naming scheme of the STL to Boost.Bimap.

There is no learning curve if you know how to use standard containers. Recent updated] aware containers, hiding the complexity of Boost.MultiIndex.]. [footnote In the same fashion, Boost.MRU will allow the creation of ['most Produce a better interface for bidirectional maps Boost.Bimap takes advantage of the narrower scope to People may end up wrapping a B.MIĬontainer in its own class every time they want to use it as aīidirectional map. Read this library's tutorial to learn about the power that has beenīut generality comes at a price: the interface that results might not be Offers great flexibility and lets you construct almost any container There is a library in Boost that alreadyĪllows the creation of this kind of container: Boost.MultiIndex. With Boost.Bimap, you can build associative containers in which both Why not take advantage of the best of both worlds?
