Returns the element at specified relative location, after transformation.
Effectively returns
std::
invoke
(
*
parent_
-
>
fun_, current_
[
n
]
)
, where
*
parent_
-
>
fun_
is the transformation function stored in the parent
transform_view
, and
current_
is the underlying iterator into
V
.
Parameters
n | - | position relative to current location. |
Return value
the transformed element
