示例1: ErrorStateTick

// ErrorStateTick is called when the DecisionTaskPoller receives a PollForDecisionTaskResponse in its polling loop
// that contains an error marker in its history.
func (f *FSM) ErrorStateTick(decisionTask *swf.PollForDecisionTaskOutput, error *SerializedErrorState, context *FSMContext, data interface{}) (*Outcome, error) {
	handler := f.errorHandlers[context.State]
	if handler == nil {
		handler = f.DecisionErrorHandler
	}
	handled, notHandled := handler(context, error.ErrorEvent, data, data, nil)
	if handled == nil {
		return nil, notHandled
	}

	//todo we are assuming all history events in the range
	//error.EarliestUnprocessedEventId to error.LatestUnprocessedEventId
	//are in the decisionTaks.History
	filteredDecisionTask := new(swf.PollForDecisionTaskOutput)
	s, e := f.systemSerializer.Serialize(decisionTask)
	if e != nil {
		return nil, e
	}
	e = f.systemSerializer.Deserialize(s, filteredDecisionTask)
	if e != nil {
		return nil, e
	}

	filtered := make([]*swf.HistoryEvent, 0)
	for _, h := range decisionTask.Events {
		if f.isErrorMarker(h) {
			continue
		}
		filtered = append(filtered, h)
	}
	filteredDecisionTask.Events = filtered
	filteredDecisionTask.StartedEventId = &error.LatestUnprocessedEventId
	filteredDecisionTask.PreviousStartedEventId = &error.EarliestUnprocessedEventId

	_, decisions, serializedState, err := f.Tick(filteredDecisionTask)
	if err != nil {
		data := f.zeroStateData()
		f.Deserialize(serializedState.StateData, data)

		return &Outcome{
			State:     serializedState.StateName,
			Decisions: decisions,
			Data:      data,
		}, nil

	}

	return nil, err
