27 Iterators library [iterators] 27.5 Iterator adaptors [predef.iterators] 27.5.3 Move iterators [move.iterators] 27.5.3.3 move_­iterator operations [move.iter.ops] 27.5.3.3.1 move_­iterator constructors [move.iter.op.const]

constexpr move_iterator();

Effects: Constructs a move_­iterator, value-initializing current. Iterator operations applied to the resulting iterator have defined behavior if and only if the corresponding operations are defined on a value-initialized iterator of type Iterator.

constexpr explicit move_iterator(Iterator i);

Effects: Constructs a move_­iterator, initializing current with i.

template <class U> constexpr move_iterator(const move_iterator<U>& u);

Effects: Constructs a move_­iterator, initializing current with u.base().

Requires: U shall be convertible to Iterator.

27.5.3.3.2 move_­iterator​::​operator= [move.iter.op=]

template <class U> constexpr move_iterator& operator=(const move_iterator<U>& u);

Effects: Assigns u.base() to current.

Requires: U shall be convertible to Iterator.

27.5.3.3.6 move_­iterator​::​operator++ [move.iter.op.incr]

constexpr move_iterator& operator++();

Effects: As if by ++current.

constexpr move_iterator operator++(int);

Effects: As if by:

move_iterator tmp = *this;
++current;
return tmp;
27.5.3.3.7 move_­iterator​::​operator-- [move.iter.op.decr]

constexpr move_iterator& operator--();

Effects: As if by --current.

constexpr move_iterator operator--(int);

Effects: As if by:

move_iterator tmp = *this;
--current;
return tmp;
27.5.3.3.8 move_­iterator​::​operator+ [move.iter.op.+]

constexpr move_iterator operator+(difference_type n) const;

Returns: move_­iterator(current + n).

27.5.3.3.9 move_­iterator​::​operator+= [move.iter.op.+=]

constexpr move_iterator& operator+=(difference_type n);

Effects: As if by: current += n;

27.5.3.3.10 move_­iterator​::​operator- [move.iter.op.-]

constexpr move_iterator operator-(difference_type n) const;

Returns: move_­iterator(current - n).

27.5.3.3.11 move_­iterator​::​operator-= [move.iter.op.-=]

constexpr move_iterator& operator-=(difference_type n);

Effects: As if by: current -= n;

27.5.3.3.13 move_­iterator comparisons [move.iter.op.comp]

template <class Iterator1, class Iterator2> constexpr bool operator==(const move_iterator<Iterator1>& x, const move_iterator<Iterator2>& y);

Returns: x.base() == y.base().

template <class Iterator1, class Iterator2> constexpr bool operator!=(const move_iterator<Iterator1>& x, const move_iterator<Iterator2>& y);

template <class Iterator1, class Iterator2> constexpr bool operator<(const move_iterator<Iterator1>& x, const move_iterator<Iterator2>& y);

Returns: x.base() < y.base().

template <class Iterator1, class Iterator2> constexpr bool operator<=(const move_iterator<Iterator1>& x, const move_iterator<Iterator2>& y);

template <class Iterator1, class Iterator2> constexpr bool operator>(const move_iterator<Iterator1>& x, const move_iterator<Iterator2>& y);

template <class Iterator1, class Iterator2> constexpr bool operator>=(const move_iterator<Iterator1>& x, const move_iterator<Iterator2>& y);

27.5.3.3.14 move_­iterator non-member functions [move.iter.nonmember]

template <class Iterator1, class Iterator2> constexpr auto operator-( const move_iterator<Iterator1>& x, const move_iterator<Iterator2>& y) -> decltype(x.base() - y.base());

Returns: x.base() - y.base().

template <class Iterator> constexpr move_iterator<Iterator> operator+( typename move_iterator<Iterator>::difference_type n, const move_iterator<Iterator>& x);

template <class Iterator> constexpr move_iterator<Iterator> make_move_iterator(Iterator i);

Returns: move_­iterator<Iterator>(i).
