event-bus

The Guava developers chose to use annotations: class EventBusChangeRecorder { @Subscribe void recordCustomerChange(ChangeEvent e) { recordChange(e.getChange()); } } ... instead of classic interfaces: class EventBusChangeRecorder implements Handler<ChangeEvent>{ void handle(ChangeEvent e) { recordChange(e.getChange()); } } This makes compile time checking impossible. So I'm wondering what is the advantage of this approach. Do you see any advantages of annotations here? Mairbek Khadikov I think that the question is answered on the Guava wiki . 来源： https://stackoverflow.com/questions/8985875

I use greenrobot EventBus library to send data between two fragments in my android app and I want to know what is the diffeence between register(Object b) method and registerSticky(Object object) method? EventBus allows you to post events that are "sticky" and by that EventBus understands events that "stick to the eventbus" for future access. If you post a normal event when there are no subscribers registered at the moment of sending, this event will be discarded. You can post a sticky event though, even if there are no subscribers to receive that at the moment, and it won't be discarded

What is the advantage of using Flux over a global event bus? I think the dispatcher is all that is needed: component publishes 'user event' with data to the dispatcher dispatcher executes handler of the subscribed store handler publishes 'update event' with the store's updated properties dispatcher executes handler of the subscribed component, and updates component state with the store's updated properties What am I missing here that I can't do without Flux? I think what others have said about application structure and the change event is important, but I should add this one thing: The

I'm starting with GWT and learning Event bus concepts now. I find this solution extremely complicated. So I tried to simplify it by writing prototype by myself to see all problems. At first I will write about my understanding of event bus (that can be completely wrong). We have events like this public class FooEvent extends GwtEvent<FooHandler> { public static Type<FooHandler> TYPE = new Type<FooHandler>(); //as event type integer ID //for.. hm.. probably some inner use in Event Bus @Override public Type<FooHandler> getAssociatedType() { return TYPE; } //for handling @Override protected void

I'm creating an Android application using EventBus for posting asynchronous broadcasts to other classes, but I'm running into an error during execution. MainActivity.java import android.content.Intent; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.EditText; import com.google.android.gms.maps.model.LatLng; import org.greenrobot.eventbus.EventBus; import org.greenrobot.eventbus.Subscribe; import org.greenrobot.eventbus.ThreadMode; public class MainActivity extends AppCompatActivity { /

Are there any Event Driven Architecture jQuery plugins? Step 1: Subscribing The subscribers subscribe to the event handler in the middle, and pass in a callback method, as well as the name of the event they are listening for... i.e. The two green subscribers will be listening for p0 events. And the blue subscriber will be listening for p1 events. Step 2: The p0 event is fired by another component to the Event Handler A p0 event is fired to the Event Handler The event handler notifies it's subscribers of the event, calling the callback methods they specified when they subscribed in Step 1:
