I hear you on the usage of Subject. I saw it is the way the GOF named it. I still prefer "Observable".
Getting at the state is done by passing the reference to the subject in your implementation. It makes for a great and simple implementation. If we could pass some metainformation as to what has changed (name of the field for example), it would make for more finegrained callbacks from the observer. What does GOF say? marcf View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3831179#3831179 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3831179 ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
