@Deprecated(since="2022-12-01") public class ListenableFutureTask<V> extends java.util.concurrent.FutureTask<V> implements ListenableFuture<V>
Deprecated.The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023AFutureTask

interface. UnlikeFutureTask
,ListenableFutureTask
does not provide an overrideabledone()
method. For similar functionality, calladdListener(java.lang.Runnable, java.util.concurrent.Executor)

create
public static <V> ListenableFutureTask<V> create(java.util.concurrent.Callable<V> callable)
Deprecated.Creates aListenableFutureTask
that will upon running, execute the givenCallable
.- Parameters:
callable
- the callable task- Since:
- 10.0
-
create
public static <V> ListenableFutureTask<V> create(java.lang.Runnable runnable, @Nullable V result)
Deprecated.Creates aListenableFutureTask
that will upon running, execute the givenRunnable
, and arrange thatget
will return the given result on successful completion.- Parameters:
runnable
- the runnable taskresult
- the result to return on successful completion. If you don't need a particular result, consider using constructions of the form:ListenableFuture<?> f = ListenableFutureTask.create(runnable, null)
- Since:
- 10.0

addListener
public void addListener(java.lang.Runnable listener, java.util.concurrent.Executor exec)
Deprecated.Description copied from interface:ListenableFuture
Registers a listener to be run on the given executor. The listener will run when theFuture
's computation is complete or, if the computation is already complete, immediately.There is no guaranteed ordering of execution of listeners, but any listener added through this method is guaranteed to be called once the computation is complete.
Exceptions thrown by a listener will be propagated up to the executor. Any exception thrown during
Executor.execute
(e.g., aRejectedExecutionException
or an exception thrown by inline execution) will be caught and logged.Note: For fast, lightweight listeners that would be safe to execute in any thread, consider
MoreExecutors.sameThreadExecutor()
. For heavier listeners,sameThreadExecutor()
carries some caveats. For example, the listener may run on an unpredictable or undesirable thread:- If this
Future
is done at the timeaddListener
is called,addListener
will execute the listener inline. - If this
Future
is not yet done,addListener
will schedule the listener to be run by the thread that completes thisFuture
, which may be an internal system thread such as an RPC network thread.
Also note that, regardless of which thread executes the
sameThreadExecutor()
listener, all other registered but unexecuted listeners are prevented from running during its execution, even if those listeners are to run in other executors.This is the most general listener interface. For common operations performed using listeners, see
Futures
. For a simplified but general listener interface, seeaddCallback()
