Wouldn't a better pattern be the discovery pattern in the services docs :
import o.a.c.l.LogFactory;
public class MyFoo {
Log logger = null;
static {
� Iterator i = Service.providers(LogFactory.class);
������ while (i.hasNext())
{
���������� LogFactory lf = (LogFactory) i.next();
logger = lf.getLogger(....);
}
��� }
public void foo()
{
logger.log("hi from foo");
}
}
Question - could o.a.c.l.LogFactory be an interface in this case? I am
guessing yes, but not sure...
So in this case, the pull discovery is maintained ("Not taken away...") yet
implementation freedom is restored...
