Interface EventListenersResolver

All Known Subinterfaces:

EventManager

All Known Implementing Classes:

DefaultEventManager

public interface EventListenersResolver

Public access interface for events listener resolution request.

Use this module to find endpoints which are able to receive events by list of events' fully-qualified names.
NOTE: Operations server will respond with list of endpoints which can receive ALL listed event types (FQNs). For example:

 List<String> fqnsToBeSupported = new ArrayList<String>();
 fqnsToBeSupported.add("org.kaaproject.test.FooEvent");
 fqnsToBeSupported.add("org.kaaproject.test.BarEvent");

 EventListenersResolver resolver = kaaClient.getEventListenerResolver();
 resolver.findEventListeners(fqnsToBeSupported, new FetchEventListeners() {
     public void onEventListenersReceived(List<String> eventListeners) {
         System.out.println("Found " + eventListeners.size() + " event targets");
     }
     public void onRequestFailed() {
         System.out.println("Request failed for some reason.");
     }
 });
 
 

This code will receive list of endpoints which support receiving event types "org.kaaproject.test.FooEvent" AND "org.kaaproject.test.BarEvent".
