Why isn't scala.util.Success.apply infinitely recursive?

Question

scala.util.Success doesn't have an apply method but inherits the one from scala.util.Try (AFAIK). But all scala.util.Try.apply does is call Success.apply surrounded by a try catch block. How is this not infinitely recursive and how does this ever trigger the catch block?

Answer 1

No, scala's Success is a case class that inherits abstract class Try. So the apply method is a built-in method generated by scala compiler, not inherited from the object Try.
