Package io.temporal.internal.sync

Class BaseRootWorkflowInboundCallsInterceptor

java.lang.Object

io.temporal.internal.sync.BaseRootWorkflowInboundCallsInterceptor

All Implemented Interfaces:

WorkflowInboundCallsInterceptor

public abstract class BaseRootWorkflowInboundCallsInterceptor
extends java.lang.Object
implements WorkflowInboundCallsInterceptor

Provides core functionality for a root WorkflowInboundCallsInterceptor that is reused by specific root RootWorkflowInboundCallsInterceptor implementations inside DynamicSyncWorkflowDefinition and POJOWorkflowImplementationFactory

Root WorkflowInboundCallsInterceptor is an interceptor that should be at the end of the WorkflowInboundCallsInterceptor interceptors chain and which encapsulates calls into Temporal internals while providing a WorkflowInboundCallsInterceptor interface for chaining on top of it.

Method Detail

init

public void init(WorkflowOutboundCallsInterceptor outboundCalls)

Description copied from interface: WorkflowInboundCallsInterceptor

Called when workflow class is instantiated. May create a WorkflowOutboundCallsInterceptor instance. The instance must forward all the calls to outboundCalls, but it may change the input parameters.

The instance should be passed into the {next.init(newWorkflowOutboundCallsInterceptor)}.

Specified by:

init in interface WorkflowInboundCallsInterceptor

Parameters:

outboundCalls - an existing interceptor instance to be proxied by the interceptor created inside this method

handleSignal

public void handleSignal(WorkflowInboundCallsInterceptor.SignalInput input)

Description copied from interface: WorkflowInboundCallsInterceptor

Called when signal is delivered to a workflow execution.

Specified by:

handleSignal in interface WorkflowInboundCallsInterceptor

handleQuery

public WorkflowInboundCallsInterceptor.QueryOutput handleQuery(WorkflowInboundCallsInterceptor.QueryInput input)

Description copied from interface: WorkflowInboundCallsInterceptor

Called when a workflow is queried.

Specified by:

handleQuery in interface WorkflowInboundCallsInterceptor

validateUpdate

public void validateUpdate(WorkflowInboundCallsInterceptor.UpdateInput input)

Description copied from interface: WorkflowInboundCallsInterceptor

Called when update workflow execution request is delivered to a workflow execution, before the update is executed.

Specified by:

validateUpdate in interface WorkflowInboundCallsInterceptor

executeUpdate

public WorkflowInboundCallsInterceptor.UpdateOutput executeUpdate(WorkflowInboundCallsInterceptor.UpdateInput input)

Description copied from interface: WorkflowInboundCallsInterceptor

Called when update workflow execution request is delivered to a workflow execution, after passing the validator.

Specified by:

executeUpdate in interface WorkflowInboundCallsInterceptor

newWorkflowMethodThread

@Nonnull
public java.lang.Object newWorkflowMethodThread(java.lang.Runnable runnable,
                                                java.lang.String name)

Description copied from interface: WorkflowInboundCallsInterceptor

Intercepts creation of the workflow main method thread

Specified by:

newWorkflowMethodThread in interface WorkflowInboundCallsInterceptor

Parameters:

runnable - thread function to run

name - name of the thread, optional

Returns:

created workflow thread. Should be treated as a pass-through object that shouldn't be manipulated in any way by the interceptor code.

newCallbackThread

@Nonnull
public java.lang.Object newCallbackThread(java.lang.Runnable runnable,
                                          java.lang.String name)

Description copied from interface: WorkflowInboundCallsInterceptor

Intercepts creation of a workflow callback thread

Specified by:

newCallbackThread in interface WorkflowInboundCallsInterceptor

Parameters:

runnable - thread function to run

name - name of the thread, optional

Returns:

created workflow thread. Should be treated as a pass-through object that shouldn't be manipulated in any way by the interceptor code.
