Ian, I see what you're saying. The way I see the object model for the application, I'm thinking more of what is an extension of what. Table Has Players, Player Has Hand, Deck Has Card, etc.
In the case of the card game, using specificity as an inheritance qualifier means that it would be pretty difficult for there to be any inheritance at all - or you would create objects that would duplicate functions of other objects. A card game is essentially objects within other objects which all interact with one master object - the table (or perhaps the Dealer - who might be the Application.cfc ;-) ). Since the player is an extension of the parent object, I can set those properties on the request as part of my "Table" configuration through my set() methods: table.setPlayer(variables.playerID); table.deal(deck.getCards()); deck.drawCard(getHand()); The Table can stand empty, but the "game" happens when players interact with the Table as it's configured with the current Deck of Cards and the other Players. For your car analogy, the same would apply: Car Has Engine, Engine Has Cylinders, Cylinder has Piston, etc. Some of those parts are shared in common with other cars made by the manufacturer, but it's the configuration of those parts in assembly that makes the car unique. A Prius object would bypass the entire assembly process if it existed, however by assembling the correct parts through the model (in addition to "Prius-only" objects), you would still return a Prius. Just my own humble interpretation of MVC with CFC's, though. I'm sure there are as many ways to define your object model as there are cards in the deck - and I've certainly made a mis-deal or two. :-) Regards, Jon On Nov 15, 2006, at 2:19 PM, Ian Skinner wrote: > Interesting, can you explore your reasoning for this design?
