operator==(chunk_by_view::iterator) (C++23)

 

class /*iterator*/		(since C++23)

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

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

Data members

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

• parent_ of type Parent (see below), which is the pointer to the parent chunk_by_view,
• current_ of type ranges::iterator_t<V>, which is the iterator to the begin of current chunk,
• next_ of type ranges::iterator_t<V>, which is the iterator to the begin of next chunk, if present.

These names are for exposition only.

Member types

Member type	Definition
value_type	ranges::subrange<ranges::iterator_t<V>>
difference_type	ranges::range_difference_t<V>
iterator_category	std::input_iterator_tag
iterator_concept	std::bidirectional_iterator_tag, if V models bidirectional_range, otherwise std::forward_iterator_tag.

Member functions

(constructor) (C++23)	constructs an iterator (public member function)
operator* (C++23)	accesses the element (public member function)
operator++operator++(int)operator--operator--(int) (C++23)	advances or decrements the underlying iterators (public member function)

Non-member functions

operator== (C++23)

compares the underlying iterators (function)
