Constructor Detail

SyncActivityWorker

public SyncActivityWorker(io.temporal.serviceclient.WorkflowServiceStubs service,
                          java.lang.String namespace,
                          java.lang.String taskQueue,
                          double taskQueueActivitiesPerSecond,
                          SingleWorkerOptions options,
                          SlotSupplier<ActivitySlotInfo> slotSupplier)

Method Detail

registerActivityImplementations

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

start

public boolean start()

Description copied from interface: Startable

This method is not required to be idempotent. It is expected to be called only once.

Specified by:

start in interface Startable

Returns:

true if the start was successful, false if the worker configuration renders the start obsolete (like no types are registered)

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

isShutdown

public boolean isShutdown()

Specified by:

isShutdown in interface Shutdownable

isTerminated

public boolean isTerminated()

Specified by:

isTerminated in interface Shutdownable

getLifecycleState

public WorkerLifecycleState getLifecycleState()

Specified by:

getLifecycleState in interface WorkerWithLifecycle

getEagerActivityDispatcher

public EagerActivityDispatcher getEagerActivityDispatcher()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
