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;
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.
