public class RingBufferLogEventHandler
extends Object
implements com.lmax.disruptor.SequenceReportingEventHandler<RingBufferLogEvent>, com.lmax.disruptor.LifecycleAware

This event handler gets passed messages from the RingBuffer as they become available. Processing of these messages is done in a separate thread, controlled by the Executor passed to the Disruptor constructor.
