Hi!
I want to be able to apply an operation f: (T,T) => T
to Option[T]
values in Scala. I want the result to be None
if any of the two values is None
.
More specifically, I want to know if is there a shorter way to do the following:
def opt_apply[T](f: (T,T) => V, x: Option[T], y: Option[T]): Option[T] = {
(x,y) match {
case (Some(u),Some(v)) => Some(f(u,v))
case _ => None
}
}
I have tryied (x zip y) map {case (u,v) => f(u,v)}
but the result is an Iterator[T]
not an Option[T]
.
Any help will be appreciated. Thanks.
