  +--org.apache.log4j.helpers.LogLog

public class LogLog
extends Object

This class used to output log statements from within the log4j package.

Log4j components cannot make log4j logging calls. However, it is sometimes useful for the user to learn about what log4j is doing. You can enable log4j internal logging by defining the log4j.configDebug variable.

All log4j internal debug calls go to System.out where as internal error messages are sent to System.err. All internal messages are prepended with the string "log4j: ".
