Class JetspeedLogger

java.lang.Object
  org.apache.jetspeed.services.logging.JetspeedLogger

public class JetspeedLogger

extends java.lang.Object

The implementation of loggers for Jetspeed. This class acts as a wrapper so that the underlying logging implementation is hidden fromthe rest of Jetspeed The current implementation uses Log4J.

Constructor Detail

JetspeedLogger

public JetspeedLogger(org.apache.log4j.Logger logger)

Constructor. Initialises this class with a given logger. If the logger is null, one is given named from this class.

Parameters:

logger - The logger to wrap

Method Detail

isDebugEnabled

public boolean isDebugEnabled()

Returns:

true if debug is enabled

isErrorEnabled

public boolean isErrorEnabled()

Checks if the current logger is enabled for error logging.

Returns:

true if error is enabled

isFatalEnabled

public boolean isFatalEnabled()

Checks if the current logger is enabled for fatal logging.

Returns:

true if fatal is enabled

isInfoEnabled

public boolean isInfoEnabled()

Checks if the current logger is enabled for info logging.

Returns:

true if info is enabled

isTraceEnabled

public boolean isTraceEnabled()
