LoggerJDK14

public class LoggerJDK14 extends Logger implements Logger
This class is used with JDK 1.4 (and higher) programs to log messages from jdo components. It extends a java.util.logging.Logger which does the actual logging.
author
Craig Russell
version
1.0

Fields Summary
protected String
sourceClassName
Class that issued logging call; set by inferCaller.
protected String
sourceMethodName
Method that issued logging call; set by inferCaller.
Constructors Summary
public LoggerJDK14(String loggerName, String bundleName)
Creates new LoggerJDK14. The Thread context class loader or the loader which loaded this class must be able to load the bundle.

param
loggerName the full domain name of this logger
param
bundleName the bundle name for message translation

        super (loggerName, bundleName);
Methods Summary
protected java.util.logging.LevelconvertLevel(int level)

level the level to convert
return
the Level instance corresponding to the int level

protected voidinferCaller()
Method to infer the caller's class name and method name. The method analyses the current stack trace, to find the method that issued the logger call. It stores the callers class and method name into fields sourceClassName and sourceMethodName.

        // Get the stack trace.
        StackTraceElement[] stack = (new Throwable()).getStackTrace();
        // Search for the first frame before the "Logger" class.
        for(int ix = 0; ix < stack.length; ix++) {
            StackTraceElement frame = stack[ix];

            if (!isLoggerClass(cname)) {

Return whether logging is enabled at the FINE level. This method is not exact because to make it accurately reflect the logging level we would have to include the JDK 1.4 java.util.logging.Level class.

return
whether logging is enabled at the fine level.

        return isLoggable(Level.FINE);
public booleanisLoggable(int levelValue)
Check if a message of the given level would actually be logged by this logger. This check is based on the Loggers effective level, which may be inherited from its parent.
