public AbstractLogger(String loggerName,
                      String bundleName,
                      ClassLoader loader)
```
    Creates a new AbstractLogger. The supplied class loader or the loader which loaded this class must be able to load the bundle.
    
    Parameters:
    
    loggerName - the full domain name of this logger
    
    bundleName - the bundle name for message translation
    
    loader - the loader used for looking up the bundle file and possibly the logging.properties or alternative file
- Method Detail
  - getMessages
```
protected static ResourceBundle getMessages()
```
    Get the message bundle for the AbstractLogger itself.
  - toString
```
public static String toString(int level)
```
    Return the string name of a level given its int value.
    
    Returns:
    
    a string representing the level
  - getBundle
```
protected ResourceBundle getBundle()
```
    Get the message bundle for the named instance of the logger.
  - getLevel
```
public int getLevel()
```
  - isLoggable
```
public boolean isLoggable()
```
    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. This method does not delegate to isLoggable(FINE) for performance reasons.
    
    Specified by:
    
    isLoggable in interface Logger
    
    Returns:
    
    whether logging is enabled at the fine level.
  - isLoggable
```
public boolean isLoggable(int levelValue)
```
    Check if a message of the given level would actually be logged by this logger. This check is based on the Logger's effective level, which may be inherited from its parent.
    
    Specified by:
    
    isLoggable in interface Logger
    
    Parameters:
    
    levelValue - the level to check
    
    Returns:
    
    true if the given message level is currently being logged.

```
    Log throwing an exception.
    This is a convenience method to log that a method is terminating by throwing an exception. The logging is done using the FINER level.
    If the logger is currently enabled for the given message level then the given arguments are stored in a LogRecord which is forwarded to all registered output handlers. The LogRecord's message is set to "THROW".
    Note that the thrown argument is stored in the LogRecord thrown property, rather than the LogRecord parameters property. Thus is it processed specially by output Formatters and is not treated as a formatting parameter to the LogRecord message property.

    getName in interface Logger
    
    Returns:
    
    logger name. Will be null for anonymous Loggers.
  - toString
```
public String toString()
```
    Prepare a printable version of this instance.
    
    Overrides:
    
    toString in class Object
    
    Returns:
    
    the String representation of this object
  - getMessage
```
protected String getMessage(String message)
```
    This method returns a string from the bundle file if possible, treating the message argument as the key. If no such key is found in the bundle, the message itself is returned.
    
    Parameters:
    
    message - the message which is used as a key to search the bundle
    
    Returns:
    
    a message either used as itself or searched in the bundle file.
  - getMessageWithPrefix
```
protected String getMessageWithPrefix(int level,
                                      String message)
```
    This method returns a string with a formatted prefix which depends on the level.
    
    Parameters:
    
    level - the level to print
    
    message - the message to print
    
    Returns:
    
    a formatted string with a level prefix.
    
    See Also:
    
    toString(int)
  - logInternal
```
protected abstract void logInternal(int level,
                                    String message)
```
    This method does the actual logging. It is expected that if a check for isLoggable is desired for performance reasons, it has already been done, as it should not be done here.
    
    Parameters:
    
    level - the level to print
    
    message - the message to print
