unordered_multimap::hash_function
unordered_multimap::key_eq
 
void reserve( size_type count );
(desde C++11)
Establece el número de cubos para el número necesario para acomodar al menos elementos count sin exceder el factor de carga máxima y refritos el contenedor, es decir, coloca los elementos en segmentos apropiados teniendo en cuenta que el número total de cubos ha cambiado. Efectivamente llama rehash(std::ceil(count / max_load_factor())) .
Original:
Sets the number of buckets to the number needed to accomodate at least count elements without exceeding maximum load factor and rehashes the container, i.e. puts the elements into appropriate buckets considering that total number of buckets has changed. Effectively calls rehash(std::ceil(count / max_load_factor())).
