Hey David, Ref: "I'm sceptical that slides are worth much without a presentation but, well, here you go! “
True except for some of the slides were used in your presentation and they layout on clear diagram form some of thew points you made. Especially the one where you renamed the command to make it clear how they were really functioning! So some of them will be quite useful for building our mental frameworks of understanding. So thank you again! Ref: "Oh, and the most important point about Publish/Subscribe can't be said too often: The think knows about itself.” Yes!!! I built StructurePulse with that concept in mind and a Publish/Subscribe technique. It was written using objectTools. IN fact everything was an object and I only used the database for persistence. I just started reviewing my code (although in 4D 2004) and saw your presentation. So I will start with this polished approach and if I need to change pr extend I will do so. I recall that my original one had the objects subscribe to specific services and then the routing object would only send messages to objects looking for them. But inn this caae it sends the message to any object that subscribes and if the object is interested it dos whatever it needs to do. If not it ignores it. So I think I’ll start with your approach this time and see how that works first. I think it will be more than enough. Anyway, thank you again David! Much Appreciated, John… ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
