NAME¶

std::ranges::chunk_view::iterator - std::ranges::chunk_view::iterator

Synopsis¶

template< bool Const > (since C++23)
class /*iterator*/ (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
* std::random_access_iterator_tag, if Base models
random_access_range. Otherwise,
iterator_concept * std::bidirectional_iterator_tag, if Base models
bidirectional_range. Otherwise,
* std::forward_iterator_tag.
value_type decltype(views::take(ranges::subrange(current_, end_), n_));.

Data members

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

Member functions¶

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

Non-member functions¶

operator==
operator<
operator> compares the underlying iterators
operator<= (function)
operator>=

(C++23)
