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 type	Definition
Parent (private)	const chunk_view if Const is true , otherwise chunk_view . ( exposition-only member type* )
Base (private)	const V if Const is true , otherwise 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 name	Definition
current_ (private)	ranges:: iterator_t < Base > , holds an iterator to the first element of current chunk in the underlying sequence (i.e. the begin of a chunk). ( exposition-only member object* )
end_ (private)	ranges:: sentinel_t < Base > , holds a sentinel to the end of the underlying sequence. ( exposition-only member object* )
n_ (private)	ranges:: range_difference_t < Base > , holds initial number of elements in the chunk (the last chunk can be smaller). ( exposition-only member object* )
missing_ (private)	ranges:: range_difference_t < Base > , 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)
