NAME¶

std::ranges::chunk_by_view::iterator::operator++,-- - std::ranges::chunk_by_view::iterator::operator++,--

Synopsis¶

constexpr /*iterator*/& operator++(); (1) (since C++23)
constexpr /*iterator*/ operator++(int); (2) (since C++23)
constexpr /*iterator*/& operator--() requires (3) (since C++23)
ranges::bidirectional_range<V>;
constexpr /*iterator*/ operator--(int) requires (4) (since C++23)
ranges::bidirectional_range<V>;

Increments or decrements the iterator.

Let parent_, current_, and next_ be the appropriate underlying (exposition-only)
data-members of iterator.

Let find-next and find-prev be appropriate (exposition-only) member functions of
ranges::chunk_by_view.

1) Equivalent to:

current_ = next_;
next_ = parent_->/*find-next*/(current_);
return *this;

The behavior is undefined if before the call to this operator current_ is equal to
next_.
2) Equivalent to: auto tmp = *this; ++*this; return tmp;
3) Equivalent to:

next_ = current_;
current_ = parent_->/*find-prev*/(next_);
return *this;

4) Equivalent to: auto tmp = *this; --*this; return tmp;

Parameters¶

(none)

Return value¶

1,3) *this
2,4) a copy of *this that was made before the change.
