public abstract class AbstractExecutionThreadService

implements Service
Deprecated.
The Google Guava Core Libraries are deprecated and will not be part of the AEM SDK after April 2023
Base class for services that can implement
startUp()
, run()
and
shutDown()
methods. This class uses a single thread to execute the
service; consider AbstractService
if you would like to manage any
threading manually.- Since:

start
Deprecated.Description copied from interface:Service
If the service state isService.State.NEW
, this initiates service startup and returns immediately. If the service has already been started, this method returns immediately without taking action. A stopped service may not be restarted.- Specified by:
start
in interfaceService
- Returns:
- a future for the startup result, regardless of whether this call initiated startup.
Calling
Future.get()
will block until the service has finished starting, and returns one ofService.State.RUNNING
,Service.State.STOPPING
orService.State.TERMINATED
. If the service fails to start,Future.get()
will throw anExecutionException
, and the service's state will beService.State.FAILED
. If it has already finished starting,Future.get()
returns immediately. Cancelling this future has no effect on the service.
-
startAndWait
Deprecated.Description copied from interface:Service
Initiates service startup (if necessary), returning once the service has finished starting. Unlike callingstart().get()
, this method throws no checked exceptions, and it cannot be interrupted.- Specified by:
startAndWait
in interfaceService
- Returns:
- the state of the service when startup finished.
-
isRunning
public final boolean isRunning()Deprecated.Description copied from interface:Service
Returnstrue
if this service is running. -
state
Deprecated.Description copied from interface:Service
Returns the lifecycle state of the service. -
stop
Deprecated.Description copied from interface:Service
If the service is starting or running, this initiates service shutdown and returns immediately. If the service is new, it is terminated without having been started nor stopped. If the service has already been stopped, this method returns immediately without taking action.- Specified by:
stop
in interfaceService
- Returns:
- a future for the shutdown result, regardless of whether this call initiated shutdown.
Calling
Future.get()
will block until the service has finished shutting down, and either returnsService.State.TERMINATED
or throws anExecutionException
. If it has already finished stopping,Future.get()
returns immediately. Cancelling this future has no effect on the service.
-
stopAndWait
Deprecated.Description copied from interface:Service
Initiates service shutdown (if necessary), returning once the service has finished stopping. If this isService.State.STARTING
, startup will be cancelled. If this isService.State.NEW
, it isterminated
without having been started nor stopped. Unlike callingstop().get()
, this method throws no checked exceptions.- Specified by:
stopAndWait
in interfaceService
- Returns:
- the state of the service when shutdown finished.
-
addListener
Deprecated.Description copied from interface:Service
Registers aService.Listener
to be executed on the given executor. The listener will have the corresponding transition method called whenever the service changes state. The listener will not have previous state changes replayed, so it is suggested that listeners are added before the service starts.There is no guaranteed ordering of execution of listeners, but any listener added through this method is guaranteed to be called whenever there is a state change.
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.- Specified by:
addListener
in interfaceService
- Parameters:
listener
- the listener to run when the service changes state is completeexecutor
- the executor in which the listeners callback methods will be run. For fast, lightweight listeners that would be safe to execute in any thread, considerMoreExecutors.sameThreadExecutor()
.- Since:
- 13.0
-
failureCause
Deprecated.Description copied from interface:Service
Returns theThrowable
that caused this service to fail.- Specified by:
failureCause
in interfaceService
- Since:
- 14.0
-
startAsync
Deprecated.Description copied from interface:Service
If the service state isService.State.NEW
, this initiates service startup and returns immediately. A stopped service may not be restarted.- Specified by:
startAsync
in interfaceService
- Returns:
- this
- Since:
- 15.0
-
stopAsync
Deprecated.Description copied from interface:Service
If the service is starting or running, this initiates service shutdown and returns immediately. If the service is new, it is terminated without having been started nor stopped. If the service has already been stopped, this method returns immediately without taking action. -
awaitRunning
public final void awaitRunning()Deprecated.Description copied from interface:Service
Waits for theService
to reach the running state.- Specified by:
awaitRunning
in interfaceService
- Since:
- 15.0
-
awaitRunning
Deprecated.Description copied from interface:Service
Waits for theService
to reach the running state for no more than the given time.- Specified by:
awaitRunning
in interfaceService
- Parameters:
timeout
- the maximum time to waitunit
- the time unit of the timeout argument- Throws:
TimeoutException
- if the service has not reached the given state within the deadline- Since:
- 15.0
-
awaitTerminated
public final void awaitTerminated()Deprecated.Description copied from interface:Service
Waits for theService
to reach the terminated state.- Specified by:
awaitTerminated
in interfaceService
- Since:
- 15.0
-
awaitTerminated
Deprecated.Description copied from interface:Service
Waits for theService
to reach a terminal state (eitherterminated
orfailed
) for no more than the given time.- Specified by:
awaitTerminated
in interfaceService
- Parameters:
timeout
- the maximum time to waitunit
- the time unit of the timeout argument- Throws:
TimeoutException
- if the service has not reached the given state within the deadline- Since:
