make_move_iterator (C++11)

 

Defined in header <iterator>
template<class Iter > move_iterator<Iter> operator+     (typename move_iterator<Iter>::difference_type n,       const move_iterator<Iter>& it );		(since C++11) (constexpr since C++17) (until C++20)
template<class Iter > constexpr move_iterator<Iter> operator+     (std::iter_difference_t<Iter> n, const move_iterator<Iter>& it );		(since C++20)

Returns the iterator it incremented by n.

This overload participates in overload resolution only if it.base()+ n is well-formed and has type Iter.

(since C++20)

Parameters

n	-	the number of positions to increment the iterator
it	-	the iterator adaptor to increment

Return value

it + n

Defect reports

The following behavior-changing defect reports were applied retroactively to previously published C++ standards.

DR	Applied to	Behavior as published	Correct behavior
LWG 3293	C++20	the non-member operator+ was constrained to require it + n is well-formed and has type Iter	changed to it.base()+ n
