Deduction guides(C++17)

 

template< class Key, class Hash, class KeyEqual, class Alloc > void swap( unordered_multiset<Key,Hash,KeyEqual,Alloc>& lhs,            unordered_multiset<Key,Hash,KeyEqual,Alloc>& rhs );		(since C++11) (until C++17)
template< class Key, class Hash, class KeyEqual, class Alloc > void swap( unordered_multiset<Key,Hash,KeyEqual,Alloc>& lhs,            unordered_multiset<Key,Hash,KeyEqual,Alloc>& rhs ) noexcept(/* see below */);		(since C++17)

Specializes the std::swap algorithm for std::unordered_multiset. 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)
