The STL associative container class is a variable sized container which supports retrieval of an element value given a search key. Each element in a multimap stores some data as its mapped value. Depends! Like. c++ search stl map vector. But, perhaps more importantly, a multimap of vectors is easier to comprehend than a map of lists of vectors, though I still wonder why you couldn't just have a map of vectors, essentially combining the vectors whose keys are equal into a single vector.
