If I understand your example correctly, it's quite similar to a std::(unordered_)map<Key, std::vector<Value> >. except that it seems to be able to handle different value-types.
In my field, this is what we call an n-tuple: http://www.gnu.org/software/gsl/manual/html_node/N_002dtuples.html http://www.gnu.org/software/gsl/manual/html_node/Ntuple-References-and-Furth... cheers, sebastien. -- ################################### # Dr. Sebastien Binet # # Lawrence Berkeley National Lab. # # 1 Cyclotron Road # # Berkeley, CA 94720 # ###################################
