object Try

The Try type represents a computation that may either result in an exception or return a success value. It is analogous to the Either type but encodes common idioms for handling exceptional cases (such as rescue/ensure which is analogous to try/finally).

    Collect the results from the given Trys into a new Try.

    Collect the results from the given Trys into a new Try. The result will be a Throw if any of the argument Trys are Throws. The first Throw in the Seq is the one which is surfaced.

  11. def fromScala[R](tr: scala.util.Try[R]): Try[R]

    Build a Try from a scala.util.Try.

    Build a Try from a scala.util.Try. This does nothing more than pattern match and translate Success and Failure to Return and Throw respectively.

  18. def orThrow[A](o: Option[A])(failure: () ⇒ Throwable): Try[A]

    Convert an scala.Option to a Try.

    Convert an scala.Option to a Try.

    For users from scala, there's also the implicit class OrThrow which allows

    import Try._
    Option(null).orThrow { new Exception("boom!") }
    o

    the Option to convert to a Try

    failure

    a function that returns the Throwable that should be returned if the option is None

  24. def withFatals[R](r: ⇒ R)(f: PartialFunction[Throwable, Try[R]]): Try[R]

    Like Try.apply but allows the caller to specify a handler for fatal errors.
