Abstract Value Members

  1. abstract def cancel(): Unit

    Permalink

    Cancels the execution of this action.

  2. abstract def isCancelled: Boolean

    Permalink

    Returns whether the action has been cancelled.

  3. abstract def isCompleted: Boolean

    Permalink

    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]

    Permalink

    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

    Permalink

    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

    Permalink

    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

    Definition Classes

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

    Permalink

    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

    Exceptions thrown

    Exception exception during action execution

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

    Permalink

    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.
