4. object TaskInterrupted extends InterruptedException with Product with Serializable

   

   signals task was interrupted *

5. def Try[A](a: ⇒ A): \/[Throwable, A]

   

   Utility function - evaluate a and catch and return any exceptions.

6. def apply[A](a: ⇒ A)(implicit pool: ExecutorService = Strategy.DefaultExecutorService): Task[A]

   

   Create a Task that will evaluate a using the given ExecutorService.

7. final def asInstanceOf[T0]: T0

   

   Definition Classes

   Any

8. def async[A](register: ((\/[Throwable, A]) ⇒ Unit) ⇒ Unit): Task[A]

   

   Create a Task from an asynchronous computation, which takes the form of a function with which we can register a callback.

   Create a Task from an asynchronous computation, which takes the form of a function with which we can register a callback. This can be used to translate from a callback-based API to a straightforward monadic version.

10. def delay[A](a: ⇒ A): Task[A]

    

    Promote a non-strict value to a Task, catching exceptions in the process.

    Promote a non-strict value to a Task, catching exceptions in the process. Note that since Task is unmemoized, this will recompute a each time it is sequenced into a larger computation. Memoize a with a lazy value before calling this function if memoization is desired.

13. def fail(e: Throwable): Task[Nothing]

    

    A Task which fails with the given Throwable.

15. def fork[A](a: ⇒ Task[A])(implicit pool: ExecutorService = Strategy.DefaultExecutorService): Task[A]

    

    Returns a Task that produces the same result as the given Future, but forks its evaluation off into a separate (logical) thread, using the given ExecutorService.

    Returns a Task that produces the same result as the given Future, but forks its evaluation off into a separate (logical) thread, using the given ExecutorService. Note that this forking is only described by the returned Task--nothing occurs until the Task is run.

16. def fromDisjunction[A <: Throwable, B](x: \/[A, B]): Task[B]

    

17. def fromMaybe[A](ma: Maybe[A])(t: ⇒ Throwable): Task[A]

    

18. def gatherUnordered[A](tasks: Seq[Task[A]], exceptionCancels: Boolean = false): Task[List[A]]

    

    Like Nondeterminism[Task].gatherUnordered, but if exceptionCancels is true, exceptions in any task try to immediately cancel all other running tasks.

    Like Nondeterminism[Task].gatherUnordered, but if exceptionCancels is true, exceptions in any task try to immediately cancel all other running tasks. If exceptionCancels is false, in the event of an error, all tasks are run to completion before the error is returned.

32. def unsafeStart[A](a: ⇒ A)(implicit pool: ExecutorService = Strategy.DefaultExecutorService): Task[A]

    

    Create a Task that starts evaluating a using the given ExecutorService right away.

    Create a Task that starts evaluating a using the given ExecutorService right away. This will start executing side effects immediately, and is thus morally equivalent to unsafePerformIO. The resulting Task cannot be rerun to repeat the effects. Use with care.
