ifA[A](ifTrue: F[A], ifFalse: F[A])(implicit F: Apply[F]): F[A]
An
if-then-elselifted into theFcontext.An
if-then-elselifted into theFcontext. This function combines the effects of thefcondcondition and of the two branches, in the order in which they are given.The value of the result is, depending on the value of the condition, the value of the first argument, or the value of the second argument.
Example:
scala> import cats.implicits._ scala> val b1: Option[Boolean] = Some(true) scala> val asInt1: Option[Int] = b1.ifA(Some(1), Some(0)) scala> asInt1.get res0: Int = 1 scala> val b2: Option[Boolean] = Some(false) scala> val asInt2: Option[Int] = b2.ifA(Some(1), Some(0)) scala> asInt2.get res1: Int = 0 scala> val b3: Option[Boolean] = Some(true) scala> val asInt3: Option[Int] = b3.ifA(Some(1), None) asInt2: Option[Int] = None
