Type Parameters:

Event - type of event (ILoggingEvent or IAccessEvent).

All Implemented Interfaces:

Appender<Event>, AppenderAttachable<Event>, ContextAware, FilterAttachable<Event>, LifeCycle

Direct Known Subclasses:

public abstract class DelegatingAsyncDisruptorAppender<Event extends DeferredProcessingAware,Listener extends AppenderListener<Event>>
extends AsyncDisruptorAppender<Event,Listener>
implements AppenderAttachable<Event>

An AsyncDisruptorAppender that delegates appending of an event to delegate appenders. This is very similar to logback's AsyncAppenderBase, except that:

• it uses a RingBuffer instead of a BlockingQueue
• it allows any number of delegate appenders, instead of just one
• it flushes appenders of type OutputStreamAppender or Flushable at the end of a batch
• it is resilient to exceptions and guarantees that all appenders are invoked
