Detailed Description
template<class _Value, class _Hash = hash<_Value>, class _Pred = std::equal_to<_Value>, class
_Alloc = std::allocator<_Value>>
class std::unordered_multiset< _Value, _Hash, _Pred, _Alloc >" A standard container
composed of equivalent keys (possibly containing multiple of each key value) in which the
elements' keys are the elements themselves.
Template Parameters:
_Value Type of key objects.
_Hash Hashing function object type, defaults to hash<_Value>.
_Pred Predicate function object type, defaults to equal_to<_Value>.
_Alloc Allocator type, defaults to allocator<_Key>.
Meets the requirements of a container, and unordered associative container
Base is _Hashtable, dispatched at compile time via template alias __umset_hashtable.

Parameters:
__pos An iterator that serves as a hint as to where the element should be inserted.
__args Arguments used to generate the element to be inserted.
Returns:
An iterator that points to the inserted element.
Note that the first parameter is only a hint and can potentially improve the performance
of the insertion process. A bad hint would cause no gains in efficiency.

__x Element to be inserted.
Returns:
An iterator that points to the inserted element.
Insertion requires amortized constant time.

_Alloc = std::allocator<_Value>> iterator std::unordered_multiset< _Value, _Hash, _Pred,
_Alloc >::insert (value_type && __x) [inline]
Inserts an element into the unordered_multiset.
Parameters:
__x Element to be inserted.
Returns:
An iterator that points to the inserted element.
Insertion requires amortized constant time.

_Alloc = std::allocator<_Value>> iterator std::unordered_multiset< _Value, _Hash, _Pred,
_Alloc >::insert (const_iterator __hint, const value_type & __x) [inline]
Inserts an element into the unordered_multiset.
Parameters:
__hint An iterator that serves as a hint as to where the element should be inserted.
__x Element to be inserted.
Returns:
An iterator that points to the inserted element.
Note that the first parameter is only a hint and can potentially improve the performance
of the insertion process. A bad hint would cause no gains in efficiency.

A template function that inserts a range of elements.
Parameters:
__first Iterator pointing to the start of the range to be inserted.
__last Iterator pointing to the end of the range.
Complexity similar to that of the range constructor.

than or equal to.

_Hash, _Pred, _Alloc >::operator= (initializer_list< value_type > __l) [inline]
Unordered_multiset list assignment operator.
Parameters:
__l An initializer_list.
This function fills an unordered_multiset with copies of the elements in the initializer
list __l.
Note that the assignment completely changes the unordered_multiset and that the resulting
unordered_set's size is the same as the number of elements assigned. Old data may be lost.

May rehash the unordered_multiset.
Parameters:
__n The new number of buckets.
Rehash will occur only if the new number of buckets respect the unordered_multiset maximum
load factor.

Prepare the unordered_multiset for a specified number of elements.
Parameters:
__n Number of elements required.

Swaps data with another unordered_multiset.
Parameters:
__x An unordered_multiset of the same element and allocator types.
This exchanges the elements between two sets in constant time. Note that the global
std::swap() function is specialized such that std::swap(s1,s2) will feed to this function.
