<p>This exchanges the elements between two multimaps in constant time. (It is only swapping a pointer, an integer, and an instance of the <code>Compare</code> 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(m1,m2) will feed to this function.</p>
<p>Whether the allocators are swapped depends on the allocator traits. </p>
