public class SimpleFutureAction<T> extends java.lang.Object implements FutureAction<T>
FutureAction holding the result of an action that triggers a single job. Examples include
count, collect, reduce.| Modifier and Type | Method and Description |
|---|---|
void |
cancel()
Cancels the execution of this action.
|
boolean |
isCancelled()
Returns whether the action has been cancelled.
|
boolean |
isCompleted()
Returns whether the action has already been completed with a value or an exception.
|
scala.collection.Seq<java.lang.Object> |
jobIds()
Returns the job IDs run by the underlying async operation.
|
<U> void |
onComplete(scala.Function1<scala.util.Try<T>,U> func,
scala.concurrent.ExecutionContext executor)
When this action is completed, either through an exception, or a value, applies the provided
function.
|
SimpleFutureAction<T> |
ready(scala.concurrent.duration.Duration atMost,
scala.concurrent.CanAwait permit)
Blocks until this action completes.
|
T |
result(scala.concurrent.duration.Duration atMost,
scala.concurrent.CanAwait permit)
Awaits and returns the result (of type T) of this action.
|
scala.Option<scala.util.Try<T>> |
value()
The value of this Future.

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