It really depends on the class it will be used in. For classes which you expect to be subclasses and where the base class should use the derived classes category, then a protected final Logger created on construction would be used.
If you want the base class and the derived class to have separate logging, or rather logging for that class only, then a private static final Logger would be used. The private keeps other classes from using it unintentionally and the final keeps it from being replaced (which you almost never want to do to one of these). The difference between package private and private could be laziness on the coders part, or could be that the logging data is shared between subclasses in the given package only. I would guess it was laziness. The usage of final is debatable, but I feel that it is useful to avoid simple assignment errors and to have a bit more insurance that Loggers won't get null'd or re-categorized. In short, there are a several different ways to get a Logger because the Logger usage varies slightly from class to class. Use the appropriate method for the logging your class needs. --jason > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:jboss- > [EMAIL PROTECTED]] On Behalf Of Christian Riege > Sent: Friday, January 11, 2002 3:54 AM > To: [EMAIL PROTECTED] > Subject: [JBoss-dev] standard for obtaining an org.jboss.logging.Logger > instance > > hi, > > is there a standard way of getting the Logger instance in JBoss? the > code is sprinkled with at least 4 different ways of doing so, i.e. > sometimes its a private variable, sometimes its protected, sometimes its > on a package level access, sometimes its declared as 'final', etc ... > how about agreeing on a standard way; that would clean up some > confusion. > > regards, > christian > > > _______________________________________________ > Jboss-development mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/jboss-developmen _______________________________________________ Jboss-development mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-development
