      Description

      The name of org.slf4j.impl.SLF4JLogger should indicate somehow that we are dealing with Log4j 2.

      Right now the class is org.slf4j.impl.SLF4JLogger

      These are the names from other bindings:
      nop : org.slf4j.helpers.NOPLogger
      simple : org.slf4j.impl.SimpleLogger
      jdk : org.slf4j.impl.JDK14LoggerAdapter
      jcl : org.slf4j.impl.JCLLoggerAdapter
      log4j : org.slf4j.impl.Log4jLoggerAdapter
      logback : ch.qos.logback.classic.Logger

      Every one of them indicates what is the binding for, in the class name (all slf4j bindings), or as part of package name (logback).

      Use case: "hook" into the functionality of the logger under slf4j to control stuff not accessible through slf4j.

      Example:
      http://code.google.com/p/okapi/source/browse/#git%2Fapplications%2Frainbow%2Fsrc%2Fmain%2Fjava%2Fnet%2Fsf%2Fokapi%2Fapplications%2Frainbow%2Flogger

      Code to reproduce this:
      =========
      import org.slf4j.Logger;
      import org.slf4j.LoggerFactory;

      public class LogHandlerFactory {
      static public void main(String [] args)

      { Logger localLogger = LoggerFactory.getLogger(LogHandlerFactory.class); String realLogger = localLogger.getClass().getName(); System.out.printf("%-8s: %s%n", args.length > 0 ? args[0] : "???", realLogger); }

      }
      =========

      Thank you,
      Mihai
