[slf4j-dev] Feature Request

   Hey Guys, 


I thought I could just write a little implementation. Basically it is your LocLogger, with a few lines changed.




package org.slf4j.cal10n;




import org.slf4j.Logger;

import org.slf4j.Marker;

import org.slf4j.MarkerFactory;

import org.slf4j.ext.LoggerWrapper;

import ch.qos.cal10n.MessageParameterObj;




/**

 * A logger specialized in localized logging. Localization is based in the <a

 * href="http://cal10n.qos.ch">CAL10N project</p>.

 * 

 * @author Ceki G&uuml;lc&uuml;

 */

public class CodeLocLogger extends LoggerWrapper implements Logger {




  private static final String FQCN = CodeLocLogger.class.getName();




  /**

   * Every localized message logged by a LocLogger will bear this marker. It

   * allows marker-aware implementations to perform additional processing on

   * localized messages.

   */

  static Marker LOCALIZED = MarkerFactory.getMarker("LOCALIZED");




  final IMessageConveyor imc;




  public CodeLocLogger(Logger logger,  IMessageConveyor imc) {

    super(logger, LoggerWrapper.class.getName());

    if(imc == null) {

      throw new IllegalArgumentException("IMessageConveyor cannot be null");

    }

    this.imc = imc;

  }




  /**

  public void trace(Enum<?> key, Object... args) {

    if (!logger.isTraceEnabled()) {

      return;

    }

    String translatedMsg = imc.getMessage(key, args);

    MessageParameterObj mpo = new MessageParameterObj(key, args);

    String msg = " [" + key.getClass().getName() + key.toString() + "] " + translatedMsg;

    if (instanceofLAL) {

      ((LocationAwareLogger) logger).log(LOCALIZED, FQCN,

          LocationAwareLogger.TRACE_INT, msg, null);
