template< class T > constexpr void swap( propagate_const<T>& lhs, propagate_const<T>& rhs );		(library fundamentals TS v2)

Specializes the swap algorithm for std::experimental::propagate_const. Swaps the pointers of lhs and rhs. Let t_ designate the private data member that is the wrapped pointer-like object, then this function is equivalent to swap(lhs.t_, rhs.t_).

Parameters

lhs, rhs

-

propagate_consts whose contents to swap

Return value

(none)

Exceptions

noexcept specification:  

noexcept(noexcept(swap(lhs.t_, rhs.t_)))

Complexity

Constant
