Advances or decrements the iterator .
Let
current_
and
last_ele_
be the underlying iterators to the begin and end of the sliding window.
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_
(if present) must be incrementable.
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_
(if present) must be decrementable.
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_
is present) must have well-defined behavior.
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_
is present) must have well-defined behavior.
Parameters
n | - | position relative to current location |
Return value

2,4)
a copy of

that was made before the change
