public class LogDirector

extends IntermediateServer

Direct logging request to appropriate log service provider.

This provides you to the way to set log service provider of some(or many) LogTap all at a time.

For example, it is assumed that your module has 4 classes which want to request logging defined as shown below:

 public class LogUtil {
     final static public LogDirector DIRECTOR = new LogDirector();
 }

 public class LogClient1 {
     final static private LogTap TAP =
     new LogTap(LogClient1.class, LogUtil.DIRECTOR);
 }

 public class LogClient2 {
     ... = new LogTap(LogClient2.class, LogUtil.DIRECTOR);
 }

 public class LogClient3 {
     ... = new LogTap(LogClient3.class, LogUtil.DIRECTOR);
 }

 public class LogClient4 {
     ... = new LogTap(LogClient4.class, LogUtil.DIRECTOR);
 }
 

Here, you can let log client classes request logging to "Log4J" service provider only by setServer with Log4jProvider.INSTANCE invocation on LogUtil.DIRECTOR of above example.

You can also chain multiple ones.
