Implicit getters/setters and interfaces

[Guest]

What's the best way around this problem with interfaces?

public interface ITest {

     function set testField(test:String):void;

}

public class Test implements ITest {

     public var testField;

}

This complains I didn't implement the interface - bull! 

Test does have a setter for testField (an implicit one).  I don't want to define an explicit one for every single field I have defined in my interface.  There doesn't seem to be a way to define getters/setters in interfaces (or the syntax just escapes me).

Do I have to do this explicit getter/setter nonsense in order to use interfaces in this way?  I'd rather not throw away this rather awesome feature of AS3 so I hope there's some easy workaround...

After asking The Google and some search (attempts) here I couldn't find anything on this, so perhaps I'm missing something obvious.  It's early in the morning...

Nothing wrong with the interface declaration. But the implementation is wrong - testField needs to be a public function matching the signature declared in the interface.

public interface ITest {

     function set testField(test:String):void;
}



public class Test implements ITest {

     var _testField:String;

     public function set testField(test:String):void

     {

          _testField= test;

     }

}

This is my problem - I want the getter/setter to be implicit in the class, I don't want to do all this:

public class Test implements ITest {

     var _testField:String;

     public function set testField(test:String):void

     {

          _testField= test;

     }

}

I know this fixes the problem but again it's throwing away an advantage of an implicit getter/setter.  (Not having to create that whole function, not to mention I can't stand underscore conventions. )

So there's really no way to avoid the function or to "declare a field" in an interface, I assume?

The only workaround, it seems, is to drop interfaces entirely and simply define the fields in a base class.  Probably not the best solution but I suppose there's little choice unless someone else knows otherwise.  I'm surprised there aren't others wondering what gives about this AS3 interface annoyance.

public class BaseTest {

     var testField:String;

}

public class Test extends BaseTest {

}

No, you cannot delcare properties in an interface - public method signatures only. And don't use underscores if you don't like them. I never use them.

Kind of limiting, don't you think?  The 'workaround' I mentioned is hardly one at all.  If AS is going to support implicit getters and setters, interfaces need to be improved on to compensate, IMO.

I've rarely run into this problem after years of Flex development, but when you do run into it, it's quite annoying.

You can define getters and setters in an interface just fine. What is wrong is that you have testField defined as a variable... it's not a variable it's a function. Get rid of the variable declaration, change to a public function and you should be fine.
