Method Summary

Modifier and Type	Method	Description
void	cancel(java.lang.String reason)
void	close()
boolean	eventLoop()
java.util.Optional<io.temporal.api.common.v1.Payloads>	getOutput()
WorkflowImplementationOptions	getWorkflowImplementationOptions()
void	handleSignal(java.lang.String signalName, java.util.Optional<io.temporal.api.common.v1.Payloads> input, long eventId)	Handle an external signal event.
io.temporal.api.failure.v1.Failure	mapExceptionToFailure(java.lang.Throwable exception)	Convert exception to the serialized Failure that can be reported to the server. This method is needed when framework code needs to serialize a TemporalFailure instance with details object produced by the application code. The framework code is not aware of DataConverter so this is working around this layering.
java.util.Optional<io.temporal.api.common.v1.Payloads>	query(io.temporal.api.query.v1.WorkflowQuery query)	Called after all history is replayed and workflow cannot make any progress if workflow task is a query.
void	start(io.temporal.api.history.v1.HistoryEvent event, ReplayWorkflowContext context)

Method Detail

start

void start(io.temporal.api.history.v1.HistoryEvent event,
           ReplayWorkflowContext context)

handleSignal

void handleSignal(java.lang.String signalName,
                  java.util.Optional<io.temporal.api.common.v1.Payloads> input,
                  long eventId)

Handle an external signal event.

eventLoop

boolean eventLoop()

getOutput

java.util.Optional<io.temporal.api.common.v1.Payloads> getOutput()

Returns:

null means no output yet

cancel

void cancel(java.lang.String reason)

close

void close()

query

java.util.Optional<io.temporal.api.common.v1.Payloads> query(io.temporal.api.query.v1.WorkflowQuery query)

Called after all history is replayed and workflow cannot make any progress if workflow task is a query.

Parameters:

query - arguments

Returns:

query result

mapExceptionToFailure

io.temporal.api.failure.v1.Failure mapExceptionToFailure(java.lang.Throwable exception)

Convert exception to the serialized Failure that can be reported to the server.
This method is needed when framework code needs to serialize a TemporalFailure instance with details object produced by the application code.
The framework code is not aware of DataConverter so this is working around this layering.

Parameters:

exception - throwable to convert

Returns:

Serialized failure

getWorkflowImplementationOptions

WorkflowImplementationOptions getWorkflowImplementationOptions()
