Returns the item contained in the Option if it is defined, otherwise, the zero element for the type A
Returns the item contained in the Option if it is defined, otherwise, the zero element for the type A
For example:
val o: Option[List[String]] = None val a: List[String] = ~o // List()
- final def |(a: => A): A
Returns the item contained in the Option if it is defined, otherwise, the provided argument.
