[Quickfix-developers] Dual LogFactory

[Alvin W. <AW...@FF...>]

Hi, can I have 2 LogFactory working at the same time. For example, one is 
MySQLLogFactory and the other is ScreenLogFactory. I found that will be 
quite useful.

thanks
Alvin

Since you can define your own log factory, you could just define one which in turn logs 
both to the MySQLLogFactory and the ScreenLogFactory.

In Java:

public class DualLogFactory
     implements LogFactory
{
     private LogFactory lf1;
     private LogFactory lf2;

     public DualLogFactory( LogFactory lf1, LogFactory lf2 ) {
         this.lf1=lf1;
         this.lf2=lf2;
     }

     public Log create( SessionID sessionID ) {
         return new DualLog( lf1.create( sessionID ), lf2.create( sessionID ) );
     }
}

public class DualLog
     implements Log
{
     Log l1;
     Log l2;

     public DualLog( Log l1, Log l2 ) {
         this.l1 = l1;
         this.l2 = l2;
     }

     public void onIncoming( String text ) {
	l1.onIncoming( text );
         l2.onIncoming( text );
     }
     ...
}

Hope that helps.

Cheers, Jörg
