  7. def attempt: Task[\/[Throwable, A]]

  8. def attemptRun: \/[Throwable, A]

    Like run, but returns exceptions as values.

  16. def handle[B >: A](f: PartialFunction[Throwable, B]): Task[B]

    Calls attempt and handles some exceptions using the given partial function.

    Calls attempt and handles some exceptions using the given partial function. Any nonmatching exceptions are reraised.

  23. def onFinish(f: (Option[Throwable]) ⇒ Task[Unit]): Task[A]

    Returns a new Task in which f is scheduled to be run on completion.

    Returns a new Task in which f is scheduled to be run on completion. This would typically be used to release any resources acquired by this Task.

  24. def or[B >: A](t2: Task[B]): Task[B]

    Runs this Task, and if it fails with an exception, runs t2.

    Runs this Task, and if it fails with an exception, runs t2. This is rather coarse-grained. Use attempt, handle, and flatMap for more fine grained control of exception handling.

  25. def run: A

    Run this Task and block until its result is available.

    Run this Task and block until its result is available. This will throw any exceptions generated by the Task. To return exceptions in an \/, use attemptRun.

  26. def runAsync(f: (\/[Throwable, A]) ⇒ Unit): Unit

    Run this computation to obtain either a result or an exception, then invoke the given callback.

    Run this computation to obtain either a result or an exception, then invoke the given callback. Any pure, non-asynchronous computation at the head of this Future will be forced in the calling thread. At the first Async encountered, control to whatever thread backs the Async and this function returns immediately.

  27. def runAsyncInterruptibly(f: (\/[Throwable, A]) ⇒ Unit, cancel: AtomicBoolean): Unit

    Run this computation to obtain an A, so long as cancel remains false.

    Run this computation to obtain an A, so long as cancel remains false. Because of trampolining, we get frequent opportunities to cancel while stepping through the trampoline, this should provide a fairly robust means of cancellation.

  28. final def synchronized[T0](arg0: ⇒ T0): T0

    Definition Classes

  29. def timed(timeoutInMillis: Long): Task[A]

    A Task which returns a TimeoutException after timeoutInMillis, and attempts to cancel the running computation.
