Object-oriented state-frozen logging

Hi Peter,

I would call this object logging, plain and simple.

Some of us, myself included, believe this is the way forward.

You could have a look at how Zinc does logging (ZnLogEvent):

This article might also help:

All in all, it is not too much effort to generate log event objects, and they can used in many different ways. Using Announcement makes this quite practical.

HTH,

Sven

Hi Sven,

thanks for the answers; especially the article was very informative. I didn't even think of using Announcements, but seeing it in action is really cool!
