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

mapUnexpectedException

WorkflowExecutionException mapUnexpectedException(java.lang.Throwable 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

getWorkflowImplementationOptions

WorkflowImplementationOptions getWorkflowImplementationOptions()
