public class ThreadedLogEventHandler

extends LogEventHandler

implements ThreadedLogEventHandlerMBean, java.lang.Runnable

Maintains a queue of log events and processes them in a background thread (via the Scheduler). This allows callers to post log events and not have to wait for them to be delivered.
