Class Eventlogger

java.lang.Object
  jgroup.util.log.Eventlogger

public class Eventlogger
extends java.lang.Object

The event logger class provides methods used for logging specific events to a disk file. It uses a simple memory based buffer, which is flushed to disk after a given number of log events, or on demand. Also, it should flush and close the file on "clean" system exits, using the shutdown hook mechanism.
