Detailed Description

   template<class _Key, class _Tp, class _Hash = hash<_Key>, class _Pred = std::equal_to<_Key>,
       class _Alloc = std::allocator<std::pair<const _Key, _Tp> >>
       class std::unordered_multimap< _Key, _Tp, _Hash, _Pred, _Alloc >" A standard container
       composed of equivalent keys (possibly containing multiple of each key value) that
       associates values of another type with the keys.

       Template Parameters:
           _Key Type of key objects.
           _Tp Type of mapped 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

       The resulting value type of the container is std::pair<const _Key, _Tp>.

       Base is _Hashtable, dispatched at compile time via template alias __ummap_hashtable.

       __args) [inline]
       Attempts to build and insert a std::pair into the unordered_multimap.

       Parameters:
           __args Arguments used to generate a new pair instance (see std::piecewise_contruct for
           passing arguments to each part of the pair constructor).

       Returns:
           An iterator that points to the inserted pair.

       (const_iterator __pos, _Args &&... __args) [inline]
       Attempts to build and insert a std::pair into the unordered_multimap.

       Parameters:
           __pos An iterator that serves as a hint as to where the pair should be inserted.
           __args Arguments used to generate a new pair instance (see std::piecewise_contruct for
           passing arguments to each part of the pair constructor).

       Returns:
           An iterator that points to the element with key of the std::pair built from __args.

       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.

       _Key, _Tp, _Hash, _Pred, _Alloc >::reserve (size_type __n) [inline]
       Prepare the unordered_multimap for a specified number of elements.

       Parameters:
           __n Number of elements required.

       Same as rehash(ceil(n / max_load_factor())).

   template<class _Key, class _Tp, class _Hash = hash<_Key>, class _Pred = std::equal_to<_Key>,
       class _Alloc = std::allocator<std::pair<const _Key, _Tp> >> void std::unordered_multimap<
       _Key, _Tp, _Hash, _Pred, _Alloc >::swap (unordered_multimap< _Key, _Tp, _Hash, _Pred,
       _Alloc > & __x) [inline]
       Swaps data with another unordered_multimap.

       Parameters:
           __x An unordered_multimap of the same element and allocator types.

       This exchanges the elements between two unordered_multimap in constant time. Note that the
       global std::swap() function is specialized such that std::swap(m1,m2) will feed to this
       function.
