All Known Implementing Classes:

Send.SendRunnable

public interface CompletionListener<T>

A listener for completion of NonBlockingClient operations. For example:

 NonBlockingClient client = // ... initialization code
 
 client.send("/kittens", "Hello kitty!", new CompletionListener() {
     public void onSuccess(NonBlockingClient c,  // c == client
                           Object ctx) {
        // ... code for handling success of send operation
     }
     public void onError(NonBlockingClient c, // c == client
                         Object ctx,
                         ClientCheckedException exception) {
        // ... code for handing failure of send operation - for example:
        exception.printStackTrace();  // The reason the operation failed.
     }
 }, null);    // This value is passed into the listener as the context argument...
