Applies
ranges::
iter_swap
to the stored underlying iterators. Formally, for every integer
0
≤ i ≤ sizeof...
(
Vs
)
, performs
ranges::
iter_swap
(
std
::
get
<
i
>
(
x.
current_
)
, std
::
get
<
i
>
(
y.
current_
)
)
, where
current_
is the underlying tuple of iterators.
This function is not visible to ordinary
unqualified
or
qualified lookup
, and can only be found by
argument-dependent lookup
when
cartesian_product_view::
iterator
<Const>
is an associated class of the arguments.
Parameters
| x, y | - | iterators to the elements to swap |
Return value
(none)
Exceptions
The exception specification is equivalent to the logical AND of the expression noexcept ( ranges:: iter_swap ( std :: get < i > ( x. current_ ) , std :: get < i > ( y. current_ ) ) ) for every integer 0 ≤ i ≤ sizeof... ( Vs ) .
