[Boost-users] Serializeable Boost hashmap with vector<long> as key

Hello ! I am looking for a hashmap that is boost::serializeable, has good performance and is implemented by boost-means. Furthermore, it must have vector<long> as key type. I tried multiindex, but it seems one cannot have keys that are not members of the value type. Boost Bimap is not serializeabel and i do not need the bimap functionality. regards, Oliver
