24.5.3.3 move_iterator operations [move.iter.ops]

24.5.3.3.1 move_iterator constructors [move.iter.op.const]

move_iterator();

1

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);

2

Effects: Constructs a move_iterator, initializing current with i.

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

3

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

4

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);

1

Effects: Assigns u.base() to current.

24.5.3.3.9 move_iterator::operator+= [move.iter.op.+=]

move_iterator& operator+=(difference_type n);

1

Effects: current += n.

2

Returns: *this.

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

move_iterator operator-(difference_type n) const;

1

Returns: move_iterator(current - n).

24.5.3.3.11 move_iterator::operator-= [move.iter.op.-=]

move_iterator& operator-=(difference_type n);

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

1

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

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

2

Returns: !(x == y).
