public interface MessageReceiver

This interface can be implemented by users of Subscriber to receive messages.

Methods

receiveMessage(PubsubMessage message, AckReplyConsumer consumer)

public abstract void receiveMessage(PubsubMessage message, AckReplyConsumer consumer)

Called when a message is received by the subscriber. The implementation must arrange for AckReplyConsumer#ack() or AckReplyConsumer#nack() to be called after processing the message.

 // This {@code MessageReceiver} passes all messages to a BlockingQueue. This method can
 // be called concurrently from multiple threads, so it is important that the queue be
 // thread-safe.
 //
 // This example is for illustration. Implementations may directly process messages instead of
 // sending them to queues.
 MessageReceiver receiver =
     new MessageReceiver() {
       public void receiveMessage(final PubsubMessage message, final AckReplyConsumer consumer) {
         if (blockingQueue.offer(message)) {
           consumer.ack();
         } else {
           consumer.nack();
         }
       }
     };
