std::swap(std::map): std::swap(std::map)

NAME

std::swap(std::map) - std::swap(std::map)

Synopsis

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

Specializes the std::swap algorithm for std::map. 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: (since C++17)
noexcept(noexcept(lhs.swap(rhs)))
