template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>>¶

class std::multiset< _Key, _Compare, _Alloc >" A standard container made up of elements, which can be retrieved in logarithmic time.

Template Parameters:

Meets the requirements of a container, a reversible container, and an associative container (using equivalent keys). For a multiset<Key> the key_type and value_type are Key.

Multisets support bidirectional iterators.

The private tree data is declared exactly the same way for set and multiset; the distinction is made entirely in how the tree functions are called (*_unique versus *_equal, same as the standard).

Returns:

This function inserts an element into the multiset. Contrary to a std::set the multiset does not rely on unique keys and thus multiple copies of the same element can be inserted.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> multiset& std::multiset< _Key, _Compare, _Alloc >::operator= (initializer_list< value_type > __l) [inline]¶

Multiset list assignment operator.

Parameters:

This function fills a multiset with copies of the elements in the initializer list __l.

Note that the assignment completely changes the multiset and that the resulting multiset's size is the same as the number of elements assigned. Old data may be lost.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> reverse_iterator std::multiset< _Key, _Compare, _Alloc >::rbegin () const [inline], [noexcept]¶

Returns a read-only (constant) reverse iterator that points to the last element in the multiset. Iteration is done in descending order according to the keys.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> reverse_iterator std::multiset< _Key, _Compare, _Alloc >::rend () const [inline], [noexcept]¶

Returns a read-only (constant) reverse iterator that points to the last element in the multiset. Iteration is done in descending order according to the keys.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> size_type std::multiset< _Key, _Compare, _Alloc >::size () const [inline], [noexcept]¶

Returns the size of the set.

template<typename _Key, typename _Compare = std::less<_Key>, typename _Alloc = std::allocator<_Key>> void std::multiset< _Key, _Compare, _Alloc >::swap (multiset< _Key, _Compare, _Alloc > & __x) [inline], [noexcept]¶

Swaps data with another multiset.

Parameters:

This exchanges the elements between two multisets in constant time. (It is only swapping a pointer, an integer, and an instance of the Compare type (which itself is often stateless and empty), so it should be quite fast.) Note that the global std::swap() function is specialized such that std::swap(s1,s2) will feed to this function.
