Class Log4jLogger

java.lang.Object

com.fasterxml.uuid.Logger

com.fasterxml.uuid.ext.Log4jLogger

public class Log4jLogger
extends Logger

Simple wrapper that allows easy connecting of JUG logging into log4j logging subsystem.

Note: using this class implies all the dependencies that the log4j subsystem in use requires (JDK 1.2 or above, in general)

Method Summary

Modifier and Type	Method and Description
static void	connectToLog4j() Static method to call to make JUG use a log4j proxy all of its logging through a log4j Logger constructed to correspond with com.fasterxml.uuid.Logger class (this generally determines log4j category output etc settings).
static void	connectToLog4j(org.apache.log4j.Logger peer) Static method to call to make JUG use to proxy all of its logging through the specified log4j Logger instance.
protected void	doLogError(String msg)
protected void	doLogInfo(String msg)
protected void	doLogWarning(String msg)
protected void	doSetOutput(PrintStream str) Note: this method is meaningless with log4j, since it has more advanced output mapping and filtering mechanisms.
protected void	doSetOutput(Writer w) Note: this method is meaningless with log4j, since it has more advanced output mapping and filtering mechanisms.

Method Detail

connectToLog4j

public static void connectToLog4j(org.apache.log4j.Logger peer)

Static method to call to make JUG use to proxy all of its logging through the specified log4j Logger instance.

Method will create a simple wrapper, and call Logger.setLogger(com.fasterxml.uuid.Logger) with the wrapper as the argument. This will then re-direct logging from the previously defined Logger (which initially is the simple JUG logger) to the new wrapper, which routes logging messages to the log4j peer Logger instance.

connectToLog4j

public static void connectToLog4j()

Static method to call to make JUG use a log4j proxy all of its logging through a log4j Logger constructed to correspond with com.fasterxml.uuid.Logger class (this generally determines log4j category output etc settings).

Method will create a simple wrapper, and call Logger.setLogger(com.fasterxml.uuid.Logger) with the wrapper as the argument. This will then re-direct logging from the previously defined Logger (which initially is the simple JUG logger) to the new wrapper, which routes logging messages to the log4j peer Logger instance.

doSetOutput

protected void doSetOutput(PrintStream str)

Note: this method is meaningless with log4j, since it has more advanced output mapping and filtering mechanisms. As such, it's a no-op
