...or anyway, I think it's 4. It's been such a long time since my last one.
As usual, the bar bet is on a controversial question that should be obvious to everyone, dammit, but the instructors at Seneca College disagree with each other. I will try to state opposing positions even-handedly, and will only confess my "side" only after others have stated some opinions. Here's the bet: In sequence diagrams, you should not send messages to actors. THIS IS OBVIOUSLY TRUE! When you send a message in a sequence diagram, you are saying that the receiving object has an operation. This is probably the main payoff of sequence diagrams: they reveal the operations and how to coordinate them. Actors are either human or just external, and we can't build operations into them either way. This is a basic difference between actors and objects. THIS IS OBVIOUSLY CRAP! When you send a message to an actor, you are showing necessary timing relationships between messages, which is a crucial feature of correct sequence diagrams. End of discussion. OK, folks, what do you think? There is a virtual beer in it for a correct answer, but you have to make a clear winning argument! -Eric ************************************************************************ * Rose Forum is a public venue for ideas and discussions. * For technical support, visit http://www.rational.com/support * * Post or Reply to: [EMAIL PROTECTED] * Subscription Requests: [EMAIL PROTECTED] * Archive of messages: * http://www.rational.com/support/usergroups/rose/rose_forum.jsp * Other Requests: [EMAIL PROTECTED] * * To unsubscribe from the list, please send email * To: [EMAIL PROTECTED] * Subject: <BLANK> * Body: unsubscribe rose_forum *************************************************************************
