void swap( multimap& other );
Exchanges the contents of the container with those of
other. Does not invoke any move, copy, or swap operations on individual elements.
All iterators and references remain valid. The past-the-end iterator is invalidated.
Pred objects must be
Swappable, and they are exchanged using unqualified call to non-member
If std::allocator_traits<allocator_type>::propagate_on_container_swap::value is true, then the allocators are exchanged using an unqualified call to non-member
swap. Otherwise, they are not swapped (and if get_allocator() != other.get_allocator(), the behavior is undefined).(since C++11)
