Subject Avoiding the unnecessary message build cost
Date Mon, 04 Apr 2011 15:27:50 GMT
      why don't we add a method in the Logger class or at least a Util with a method like
the following one in order to avoid the cost of the message build.
      In this way we'll not have to build the message unless the priority is enabled for the

      I'll wait for your thoughts.


import org.apache.log4j.Logger;

import org.apache.log4j.Priority;

public class LoggerUtil {

    static public void log(Logger logger, Priority priority, Object... objs){

        if (logger.isEnabledFor(priority) ){

            StringBuffer sb = new StringBuffer();

            for(Object obj : objs){

                sb.append( obj.toString() );


            logger.log(priority, sb.toString() );
