Interface EventNotifier

public interface EventNotifier

EventNotifier class is used to notify events and check status of events. The events are raised asynchronously. This class does not guarantee the order in which the events will be delivered to the subscribers.

Custom code to trigger event for success or fail order: Say, we want to write a post processor which will trigger event when order is successful or failed.

 
    import com.konylabs.middleware.api.events.EventData;
    import com.konylabs.middleware.common.DataPostProcessor2;
    import com.konylabs.middleware.controller.DataControllerRequest;
    import com.konylabs.middleware.controller.DataControllerResponse;
    import com.konylabs.middleware.dataobject.Result;
    
    public class PostProcessorToTriggerEvents implements DataPostProcessor2 {

      @Override
      public Object execute(Result result, DataControllerRequest request,
          DataControllerResponse response) throws Exception {
        EventData eventData;
        if (response.getStatusCode() == 200) {
          eventData = new EventData("apps/order/success", response.getResponse());
          eventData.addAdditionalMetadata("orderId", result.getParamValueByName("orderId"));
        } else {
          eventData = new EventData("apps/order/fail", response.getResponse());
          eventData.addAdditionalMetadata("trackingId", result.getParamValueByName("trackingId"));
        }

        eventData.addAdditionalMetadata("userId", result.getParamValueByName("userId"));
        eventData.addAdditionalMetadata("product", result.getParamValueByName("product"));
        request.getServicesManager().getEventNotifier().notify(eventData);
        return result;
      }
    }
