24.5.3.3 move_iterator operations [move.iter.ops] 24.5.3.3.1 move_iterator constructors [move.iter.op.const]

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.

explicit move_iterator(Iterator i);

Effects: Constructs a move_iterator, initializing current with i.

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

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

Requires: U shall be convertible to Iterator.

24.5.3.3.2 move_iterator::operator= [move.iter.op=]

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

Effects: Assigns u.base() to current.

Requires: U shall be convertible to Iterator.

24.5.3.3.6 move_iterator::operator++ [move.iter.op.incr]

move_iterator& operator++();

move_iterator operator++(int);

Effects:

move_iterator tmp = *this;
++current;
return tmp;

24.5.3.3.7 move_iterator::operator-- [move.iter.op.decr]

move_iterator& operator--();

move_iterator operator--(int);

Effects:

move_iterator tmp = *this;
--current;
return tmp;

24.5.3.3.8 move_iterator::operator+ [move.iter.op.+]

move_iterator operator+(difference_type n) const;

Returns: move_iterator(current + n).

24.5.3.3.10 move_iterator::operator- [move.iter.op.-]

move_iterator operator-(difference_type n) const;

Returns: move_iterator(current - n).

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

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

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

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

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

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

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

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

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

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

template <class Iterator1, class Iterator2> 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> move_iterator<Iterator> operator+( typename move_iterator<Iterator>::difference_type n, const move_iterator<Iterator>& x);

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

Returns: move_iterator<Iterator>(i).
