Prepare the unordered_multiset for a specified number of elements.
Parameters
__n Number of elements required.
Same as rehash(ceil(n / max_load_factor())).

_Alloc = allocator<_Value>> size_type std::unordered_multiset< _Value, _Hash, _Pred, _Alloc >::size ()
const [inline], [noexcept]
Returns the size of the unordered_multiset.

_Alloc = allocator<_Value>> void std::unordered_multiset< _Value, _Hash, _Pred, _Alloc >::swap
(unordered_multiset< _Value, _Hash, _Pred, _Alloc > & __x) [inline], [noexcept]
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.
