std::ranges::chunk_view<V>::iterator

template< bool Const >
class /*iterator*/

(since C++23)
(exposition only*)

The return type of chunk_view::begin, and of chunk_view::end when the underlying view V is a common_range.

Present only if V models forward_range.

The type /*iterator*/<true> is returned by the const-qualified overloads. The type /*iterator*/<false> is returned by the non-const-qualified overloads.

Member types

Member	Definition
`Parent` (private)	`maybe-const` <Const,chunk_view> (exposition-only member type*)
`Base` (private)	`maybe-const` <Const,V> (exposition-only member type*)
`iterator_category`	`std::input_iterator_tag`
`iterator_concept`	`std::random_access_iterator_tag`, if `Base` models `random_access_range`. Otherwise, `std::bidirectional_iterator_tag`, if `Base` models `bidirectional_range`. Otherwise, `std::forward_iterator_tag`.
`value_type`	`decltype(views::take(ranges::subrange(current_, end_), n_));`.
`difference_type`	`ranges::range_difference_t<Base>`

Data members

Member	Description
`ranges::iterator_t<Base>` `current_` (private)	an iterator to the first element of current chunk in the underlying sequence (i.e., the begin of a chunk) (exposition-only member object*)
`ranges::sentinel_t<Base>` `end_` (private)	a sentinel to the end of the underlying sequence (exposition-only member object*)
`ranges::range_difference_t<Base>` `n_` (private)	an initial number of elements in the chunk (the last chunk can be smaller) (exposition-only member object*)
`ranges::range_difference_t<Base>` `missing_` (private)	an integer that is usually equals to `ranges::advance(current_, n_, end_);` (exposition-only member object*)

Member functions

(constructor)	constructs an iterator (public member function)
base	returns an iterator to current element (public member function)
operator*	accesses the element (public member function)
operator[]	accesses an element by index (public member function)
operator++operator++(int)operator--operator--(int)operator+=operator-=	advances or decrements the underlying iterator (public member function)

Non-member functions

operator==operator<operator>operator<=operator>=operator<=> (C++23)	compares the underlying iterators (function)
operator+operator- (C++23)	performs iterator arithmetic (function)
