Method Detail

start

void start(HistoryEvent event,
           DecisionContext context)
    throws java.lang.Exception

Throws:

java.lang.Exception

handleSignal

void handleSignal(java.lang.String signalName,
                  byte[] input,
                  long eventId)

Handle an external signal event.

eventLoop

boolean eventLoop()
           throws java.lang.Throwable

Throws:

java.lang.Throwable

getOutput

byte[] getOutput()

Returns:

null means no output yet

cancel

void cancel(java.lang.String reason)

close

void close()

getNextWakeUpTime

long getNextWakeUpTime()

Returns:

time at which workflow can make progress. For example when Workflow.sleep(long) expires.

query

byte[] query(WorkflowQuery query)

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

Parameters:

query -

mapUnexpectedException

WorkflowExecutionException mapUnexpectedException(java.lang.Exception failure)

Convert exception that happened in the framework code to the format that ReplayWorkflow implementation understands. The framework code is not aware of DataConverter so this is working around this layering.

Parameters:

failure - Unexpected failure cause

Returns:

Serialized failure

mapError

WorkflowExecutionException mapError(java.lang.Error failure)

getWorkflowImplementationOptions

WorkflowImplementationOptions getWorkflowImplementationOptions()
