6. def apply(): A

   Syncrhonously blocks until the value is ready, then returns it.

   Syncrhonously blocks until the value is ready, then returns it. WARNING: May block indefinitely. A kitten dies every time you call this method.

   Definition Classes

   Promise → Function0

7. final def asInstanceOf[T0]: T0

   Definition Classes

   Any

8. def break: Unit

   Breaks the promise.

   Breaks the promise. After this method finishes, any registered continuation will not receive the value. If evaluation has not yet started, it will never start.

9. def broken: Boolean

   Indicates whether the promise has been broken.

   Indicates whether the promise has been broken. A broken promise is never fulfilled.

13. def errorTo(k: (Throwable) ⇒ Unit): Unit

    Registers the given error handler as a continuation receiving errors thrown by the evaluation.

14. def filter(p: (A) ⇒ Boolean): Promise[A]

16. def flatMap[B](f: (A) ⇒ Promise[B]): Promise[B]

    Registers the given function as a continuation, returning the result of that function.

17. def fulfill(a: ⇒ A): Unit

    Sets the value of this promise, out of band.

    Sets the value of this promise, out of band. WARNING: Once the value of a promise is set, it is forever immutable.

18. def fulfilled: Boolean

    Indicates whether the evaluation of this promise has finished.

19. def get: A

    Syncrhonously blocks until the value is ready, then returns it.

    Syncrhonously blocks until the value is ready, then returns it. WARNING: May block indefinitely. A kitten dies every time you call this method.

22. final def isInstanceOf[T0]: Boolean

23. def map[B](f: (A) ⇒ B): Promise[B]

    Registers the given function as a continuation, returning a promise of the result.

27. def spec[B](f: (A) ⇒ B, actual: Promise[A])(implicit equality: Equal[A]): Promise[B]

    Speculative concurrency.

    Speculative concurrency. In the expression guess.spec(f, actual) the value of guess is an inexpensive guess at the value and actual is the actual value, usually a more expensive computation. The function f is speculatively applied to the guess. Once the actual value is available, it's compared with the guess. If the guess was correct, we will have already applied f to the correct value, saving time. If the guess was incorrect, then f is applied to the value of actual.

28. implicit val strategy: Strategy

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

    Definition Classes

    AnyRef

30. def threw: Boolean

    Indicates whether the evaluation of this promise threw an error.

31. def to(k: (A) ⇒ Unit): Unit

    Registers the given actor or effect as a continuation receiving the promised value.
