Defined in header <set>

    class Key,
    class Compare = std::less<Key>,
    class Allocator = std::allocator<Key>

> class multiset;

Multiset is an associative container that contains a sorted set of objects of type Key. Unlike set, multiple keys with equal values are allowed. Sorting is done using the key comparison function Compare. Search, insertion, and removal operations have logarithmic complexity.

The order of the elements that compare equivalent is the order of insertion and does not change. (since C++11)

std::multiset meets the requirements of Container, AllocatorAwareContainer, AssociativeContainer and ReversibleContainer.

Notes

The member types iterator and const_iterator may be aliases to the same type. Since iterator is convertible to const_iterator, const_iterator should be used in function parameter lists to avoid violations of the One Definition Rule.
