Log4JLogger

extends Object
implements Serializable Log

java.lang.Object
↳	org.apache.commons.logging.impl.Log4JLogger

Class Overview

Implementation of Log that maps directly to a Logger for log4J version 1.2.

Initial configuration of the corresponding Logger instances should be done in the usual manner, as outlined in the Log4J documentation.

The reason this logger is distinct from the 1.3 logger is that in version 1.2 of Log4J:

class Logger takes Priority parameters not Level parameters.
class Level extends Priority

Log4J1.3 is expected to change Level so it no longer extends Priority, which is a non-binary-compatible change. The class generated by compiling this code against log4j 1.2 will therefore not run against log4j 1.3.

message	to log
t	log this cause

public void debug (Object message)

Logs a message with org.apache.log4j.Priority.DEBUG.

Parameters

message	to log

public void error (Object message)

Logs a message with org.apache.log4j.Priority.ERROR.

Parameters

message	to log

public void error (Object message, Throwable t)

Logs a message with org.apache.log4j.Priority.ERROR.

Parameters

message	to log
t	log this cause

public void fatal (Object message)

Logs a message with org.apache.log4j.Priority.FATAL.

Parameters

message	to log

public void fatal (Object message, Throwable t)

Logs a message with org.apache.log4j.Priority.FATAL.

Parameters

message	to log
t	log this cause

public Logger getLogger ()

Return the native Logger instance we are using.

public void info (Object message)

Logs a message with org.apache.log4j.Priority.INFO.

Parameters

message	to log

public void info (Object message, Throwable t)

Logs a message with org.apache.log4j.Priority.INFO.

Parameters

message	to log
t	log this cause

public boolean isDebugEnabled ()

Check whether the Log4j Logger used is enabled for DEBUG priority.

Returns

true if debug is enabled in the underlying logger.

public boolean isErrorEnabled ()

Check whether the Log4j Logger used is enabled for ERROR priority.

Returns

true if error is enabled in the underlying logger.

public boolean isFatalEnabled ()

Check whether the Log4j Logger used is enabled for FATAL priority.

Returns

true if fatal is enabled in the underlying logger.

public boolean isInfoEnabled ()

Parameters

message	to log

public void trace (Object message, Throwable t)

Logs a message with org.apache.log4j.Priority.TRACE. When using a log4j version that does not support the TRACE level, the message will be logged at the DEBUG level.

Parameters
