public class Logger

extends java.lang.Object

Simple Logging class that emulates Java2 logger API. There is only one difference: an integer value is used as log level.
Equivalence with Java2 logger values is as follows:

0 - logging disabled
1 - severe
2 - warning
3 - info
4 - config
5 - fine
6 - finer
7 - finest

Example of use :

 
 logger = Logger.getLogger("com.mydomain.mypackage");
 logger.setLevel( 7 );
 logger.info("here I start logging");
 ...
 logger.severe("I found a big problem!");
 ...
 

output is sent to System.err by default. But you may want to customize this by replacing the log method.
