Advances or decrements the iterator.
1) Equivalent to:
Before the invocation, the
current_ = ranges::next(current_); last_ele_ = ranges::next(last_ele_); // if last_ele_ is present return *this;
current_ and last_ele_
2) Equivalent to:
auto tmp =
*this;
++*this;
return tmp;
3) Equivalent to:
Before the invocation, the
current_ = ranges::prev(current_); last_ele_ = ranges::prev(last_ele_); // if last_ele_ is present return *this;
current_ and last_ele_
4) Equivalent to:
auto tmp =
*this;
--*this;
return tmp;
5) Equivalent to:
Before the invocation, the expressions current_ + n and last_ele_ + n (if
current_ = current_ + n; last_ele_ = last_ele_ + n; // if last_ele_ is present return *this;
last_ele_
6) Equivalent to:
Before the invocation, the expressions current_ - n and last_ele_ - n (if
current_ = current_ - n; last_ele_ = last_ele_ - n; // if last_ele_ is present return *this;
last_ele_
Parameters
| n | - | position relative to current location |
Return value
1,3,5,6) *this
2,4) a copy of *this that was made before the change
