Wait--that doesn't expose the getters. Hmmmm... Okay, substitute the interface with a superclass (say, AbstractModel) that has the getters, but not the setters. Then expose the Model object as AbstractModel everywhere except inside the Control class.
I've never tried that, but I think it should work. A bit weird, though. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Keesey Sent: Thursday, August 24, 2006 6:46 PM To: 'Flashcoders mailing list' Subject: RE: [Flashcoders] Protect model setters from being called by anyclassexcept Controller In AS3.0 I think it can be package-private, but until then.... One way is to have the Model class satisfy an interface that lacks the property (of course, in AS2.0, all interfaces lack properties...), and then only expose the model class as the interface elsewhere. interface IModel { function anybodyCanUseThis():Void; } class Model extends Object implements IModel { public function Model() { super(); } public function get prop():Object { return _prop; } public function set prop(p:Object):Void { _prop = p; } public function anybodyCanUseThis():Void { trace("anybodyCanUseThis()"); } private var _prop:Object; } class Control extends Object { public function Control() { super(); _model = new Model(); } public function get model():IModel { return _model; } private function doSomethingWithModel():Void { _model.prop = "Here we can access the property."; } private var _model:Model; } class SomeOtherClass extends Object { public function SomeOtherClass() { super(); _control = new Control(); _control.model.anybodyCanUseThis(); _control.model.prop = "This line will cause a compiler error."; } private var _control:Control; } -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steven Sacks | BLITZ Sent: Thursday, August 24, 2006 6:37 PM To: Flashcoders mailing list Subject: [Flashcoders] Protect model setters from being called by any classexcept Controller Hi, I have a model class that has a bunch of getters and setters. Example: private var _prop:Object; function get prop():Object { return _prop; } function set prop(p:Object) { _prop = p; } I have a controller class that instantiates that model. I'm wondering if there is some way to prevent any other class from using the setter methods of the model except the controller class. They still should be able to access the getters. I want to prevent future developers from being able to access the model setters from anywhere except the controller in order to enforce proper MVC patterns.
