unordered_multiset::hash_function
unordered_multiset::key_eq
 
void reserve( size_type count );
(depuis C++11)
Définit le nombre de seaux pour le nombre nécessaire pour accueillir les éléments count au moins sans dépasser le facteur de charge maximale et Rehash le conteneur, c'est à dire met les éléments dans des seaux appropriées compte tenu que le nombre total de godets a changé. Appelle effectivement 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())).
