Abstract Value Members

  1. abstract def cancel(): Unit

    Cancels the execution of this action.

  2. abstract def isCancelled: Boolean

    Returns whether the action has been cancelled.

  3. abstract def isCompleted: Boolean

    Returns whether the action has already been completed with a value or an exception.

    Returns whether the action has already been completed with a value or an exception.

  4. abstract def jobIds: Seq[Int]

    Returns the job IDs run by the underlying async operation.

    Returns the job IDs run by the underlying async operation.

    This returns the current snapshot of the job list. Certain operations may run multiple jobs, so multiple calls to this method may return different lists.

  5. abstract def onComplete[U](func: (Try[T]) ⇒ U)(implicit executor: ExecutionContext): Unit

    When this action is completed, either through an exception, or a value, applies the provided function.

    When this action is completed, either through an exception, or a value, applies the provided function.

  6. abstract def ready(atMost: Duration)(implicit permit: CanAwait): FutureAction.this.type

    Blocks until this action completes.

    Blocks until this action completes.

    atMost

    maximum wait time, which may be negative (no waiting is done), Duration.Inf for unbounded waiting, or a finite positive duration

    returns

    this FutureAction

  7. abstract def result(atMost: Duration)(implicit permit: CanAwait): T

    Awaits and returns the result (of type T) of this action.

    Awaits and returns the result (of type T) of this action.

    atMost

    maximum wait time, which may be negative (no waiting is done), Duration.Inf for unbounded waiting, or a finite positive duration

    returns

    the result value if the action is completed within the specific maximum wait time

  10. abstract def value: Option[Try[T]]

    The value of this Future.

    The value of this Future.

    If the future is not completed the returned value will be None. If the future is completed the value will be Some(Success(t)) if it contains a valid result, or Some(Failure(error)) if it contains an exception.
