template< class Key, class T, class Compare, class Alloc > void swap( multimap<Key,T,Compare,Alloc>& lhs, multimap<Key,T,Compare,Alloc>& rhs );		(until C++17)
template< class Key, class T, class Compare, class Alloc > void swap( multimap<Key,T,Compare,Alloc>& lhs, multimap<Key,T,Compare,Alloc>& rhs ) noexcept(/* see below */);		(since C++17)

Specializes the std::swap algorithm for std::multimap. Swaps the contents of lhs and rhs. Calls lhs.swap(rhs).

Parameters

lhs, rhs

-

containers whose contents to swap

Return value

(none)

Complexity

Constant.

Exceptions

noexcept specification: noexcept(noexcept(lhs.swap(rhs)))

(since C++17)
