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

template< bool Const > class /*iterator*/		(since C++23)

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

Used 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.

The name of this class template (shown here as /*iterator*/) is unspecified.

Data members

Typical implementations of /*iterator*/ hold four non-static data members:

• current_ of type ranges::iterator_t<Base>, that holds an iterator to the first element of current chunk in the underlying sequence (i.e. the begin of a chunk);
• end_ of type ranges::sentinel_t<Base>, that holds a sentinel to the end of the underlying sequence;
• n_ of type ranges::range_difference_t<Base>, that holds initial number of elements in the chunk (the last chunk can be smaller);
• missing_ of type ranges::range_difference_t<Base>, that usually equals to ranges::advance(current_, n_, end_);.

These names are for exposition only.

Member types

Member type	Definition
Parent (private)	const chunk_view if Const is true, otherwise chunk_view. The name is for exposition only.
Base (private)	const V if Const is true, otherwise V. The name is for exposition only.
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>

Member functions

(constructor) (C++23)	constructs an iterator (public member function)
base (C++23)	returns an iterator to current element (public member function)
operator* (C++23)	accesses the element (public member function)
operator[] (C++23)	accesses an element by index (public member function)
operator++operator++(int)operator--operator--(int)operator+=operator-= (C++23)	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)
