Class Jdk14Logger

public class Jdk14Logger extends Object implements Log, Serializable

Implementation of the org.apache.commons.logging.Log interface that wraps the standard JDK logging mechanisms that were introduced in the Merlin release (JDK 1.4).

Field Summary
protected static Level	dummyLevel This member variable simply ensures that any attempt to initialise this class in a pre-1.4 JVM will result in an ExceptionInInitializerError.
protected Logger	logger The underlying Logger implementation we are using.
protected String	name The name of the logger we are wrapping.

Constructor Summary
	Jdk14Logger(String name) Construct a named instance of this Logger.

Method Summary
void	debug(Object message) Logs a message with `java.util.logging.Level.FINE`.
void	debug(Object message, Throwable exception) Logs a message with `java.util.logging.Level.FINE`.
void	error(Object message) Logs a message with `java.util.logging.Level.SEVERE`.
void	error(Object message, Throwable exception) Logs a message with `java.util.logging.Level.SEVERE`.
void	fatal(Object message) Logs a message with `java.util.logging.Level.SEVERE`.
void	fatal(Object message, Throwable exception) Logs a message with `java.util.logging.Level.SEVERE`.
Logger	getLogger() Return the native Logger instance we are using.
void	info(Object message) Logs a message with `java.util.logging.Level.INFO`.
void	info(Object message, Throwable exception) Logs a message with `java.util.logging.Level.INFO`.
boolean	isDebugEnabled() Is debug logging currently enabled?
boolean	isErrorEnabled() Is error logging currently enabled?
boolean	isFatalEnabled() Is fatal logging currently enabled?
boolean	isInfoEnabled() Is info logging currently enabled?
boolean	isTraceEnabled() Is trace logging currently enabled?
boolean	isWarnEnabled() Is warn logging currently enabled?
void	trace(Object message) Logs a message with `java.util.logging.Level.FINEST`.
void	trace(Object message, Throwable exception) Logs a message with `java.util.logging.Level.FINEST`.
void	warn(Object message) Logs a message with `java.util.logging.Level.WARNING`.
void	warn(Object message, Throwable exception) Logs a message with `java.util.logging.Level.WARNING`.

This member variable simply ensures that any attempt to initialise this class in a pre-1.4 JVM will result in an ExceptionInInitializerError. It must not be private, as an optimising compiler could detect that it is not used and optimise it away.
