Defined in header <iterator>
template< class Iterator > class move_iterator;		(since C++11)

std::move_iterator is an iterator adaptor which behaves exactly like the underlying iterator (which must be at least an InputIterator), except that dereferencing converts the value returned by the underlying iterator into an rvalue. If this iterator is used as an input iterator, the effect is that the values are moved from, rather than copied from.

Member types

Member type	Definition
iterator_type	Iterator
difference_type	std::iterator_traits<Iterator>::difference_type
pointer	Iterator
value_type	std::iterator_traits<Iterator>::value_type
iterator_category	std::iterator_traits<Iterator>::iterator_category
reference	value_type&& (until C++17) If std::iterator_traits<Iterator>::reference is a reference, this is the rvalue reference version of the same type. Otherwise (such as if the wrapped iterator returns by value), this is std::iterator_traits<Iterator>::reference unchanged (since C++17)

Member functions

(constructor)	constructs a new iterator adaptor (public member function)
operator=	assigns another iterator (public member function)
base	accesses the underlying iterator (public member function)
operator*operator->	accesses the pointed-to element (public member function)
operator[]	accesses an element by index (public member function)
operator++operator++(int)operator+=operator+operator--operator--(int)operator-=operator-	advances or decrements the iterator (public member function)

Member objects

Member name	Definition
current (private)	a copy of the base() iterator, the name is for exposition only

Non-member functions

operator==operator!=operator<operator<=operator>operator>=	compares the underlying iterators (function template)
operator+	advances the iterator (function template)
operator-	computes the distance between two iterator adaptors (function template)
