(LMAX disruptor)How to get data by myself not by callback?

i learn that LMAX disruptor is a High Performance Inter-Thread Messaging Library. But when i try to use it ,i found that the eventhandler use a callback method to process the data.

void onEvent(T event,
       long sequence,
       boolean endOfBatch)
         throws java.lang.Exception

Called when a publisher has published an event to the RingBuffer

But if i don't use callback to get data, i write a while(true) to get data by my self, what should i do ?

thanks!

You should write your callback so it pushes the event into a queue. You can then iterate over the queue.

Queue<Event> queue = new ArrayBlockingQueue(10);

void onEvent(Event event,
        long sequence,
        boolean endOfBatch)
        throws java.lang.Exception {
    queue.add(event);
}

public void test() {
    for ( Event event : queue ) {
        // Your stuff here.
    }
}
