Class RingBufferLogEventTranslator

java.lang.Object

org.apache.logging.log4j.core.async.RingBufferLogEventTranslator

All Implemented Interfaces:

com.lmax.disruptor.EventTranslator<RingBufferLogEvent>

public class RingBufferLogEventTranslator
extends Object
implements com.lmax.disruptor.EventTranslator<RingBufferLogEvent>

This class is responsible for writing elements that make up a log event into the ringbuffer RingBufferLogEvent. After this translator populated the ringbuffer event, the disruptor will update the sequence number so that the event can be consumed by another thread.

Usage note: This class is only used on the thread that created it.
