Class BaseSubscriptionListener

java.lang.Object

com.caplin.streamlink.BaseSubscriptionListener

All Implemented Interfaces:

SubscriptionListener

public class BaseSubscriptionListener
extends java.lang.Object
implements SubscriptionListener

Adapter class implementing the SubscriptionListener methods

This is a helper class to reduce the code needed to implement the SubscriptionListener interface.

Simply extend this class and override the required methods rather than implement the full SubscriptionListener interface.

A trivial implementation would be as follows :

import com.caplin.streamlink.BaseSubscriptionListener;
import com.caplin.streamlink.NewsEvent;
import com.caplin.streamlink.RecordType1Event;
import com.caplin.streamlink.Subscription;
import com.caplin.streamlink.SubscriptionErrorEvent;
import com.caplin.streamlink.SubscriptionListener;

public class BaseSubscriptionListenerSnippet
{
        
        public BaseSubscriptionListenerSnippet()
        {
                // Subscribe to the record.
                SubscriptionListener listener = new BaseSubscriptionListener() {
                        
                        // Print error message if there is a subscription error.
                        @Override
                        public void onSubscriptionError(Subscription subscription,
                        SubscriptionErrorEvent event) {
                                
                                System.out.println("Error: Subject " + event.getSubject()
                                + " is " + event.getError());
                        }
                        
                        // Print latest record values.
                        @Override
                        public void onRecordUpdate(Subscription subscription,
                        RecordType1Event event) {
                                
                                System.out.println("Record update for " + event.getSubject() + " fields: "

                        NewsEvent event) {
                                
                                System.out.println("News Event: " + event.getSubject()
