SyncActivityWorker

public SyncActivityWorker(io.temporal.serviceclient.WorkflowServiceStubs service,
                          java.lang.String namespace,
                          java.lang.String taskQueue,
                          double taskQueueActivitiesPerSecond,

                          SingleWorkerOptions options)

Method Detail

registerActivityImplementations

public void registerActivityImplementations(java.lang.Object... activitiesImplementation)

start

public void start()

Specified by:

start in interface Startable

isStarted

public boolean isStarted()

Specified by:

isStarted in interface Startable

isShutdown

public boolean isShutdown()

Specified by:

isShutdown in interface Shutdownable

isTerminated

public boolean isTerminated()

Specified by:

isTerminated in interface Shutdownable

shutdown

public java.util.concurrent.CompletableFuture<java.lang.Void> shutdown(ShutdownManager shutdownManager,
                                                                       boolean interruptTasks)

Specified by:

shutdown in interface Shutdownable

Parameters:

shutdownManager - provides toolset to get a Future for a shutdown of instances that have both non-blocking and not returning a Future on a completion shutdown methods (like ExecutorService.shutdown())

interruptTasks - if the threads processing user code (like workflows, workflow tasks or activities) should be interrupted, or we want to wait for their full graceful completion

Returns:

CompletableFuture which should be completed when awaiting downstream dependencies can proceed with their own shutdown. Should never be completed exceptionally CompletableFuture.exceptionally(Function) as downstream dependencies have no use of this information (they need to perform a shutdown anyway), and it complicates the shutdown flow.

awaitTermination

public void awaitTermination(long timeout,
                             java.util.concurrent.TimeUnit unit)

Specified by:

awaitTermination in interface Shutdownable

suspendPolling

public void suspendPolling()

Description copied from interface: Suspendable

Do not make new poll requests. Outstanding long polls still can return tasks after this method was called.

Specified by:

suspendPolling in interface Suspendable

resumePolling

public void resumePolling()

Description copied from interface: Suspendable

Allow new poll requests.

Specified by:

resumePolling in interface Suspendable

isSuspended

public boolean isSuspended()

Specified by:

isSuspended in interface Suspendable

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
