vector::swap

 

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

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