I see interfaces with default implementation as a anti-pattern, actually. I
don't use it. Also, IMHO mixins are good for utility code, other than that
it might smell.
Maybe vala should have a literal mixin, with only virtual methods and not
instantiable nor castable. Only useful to add utility met
If you want your interface to provide, not just default implementations,
but methods your classes should not need to implement they self, use
virtual methods, you can provide an implementation for this method your
derived classes don't need to implement but inherited. Static methods can
be used to
Even better, try this main instead the previous:
int main () {
IMixinInterface fooer = new NothingSpecialFooer();
fooer.foo();
fooer = new TheSpecialFooer();
fooer.foo();
return 0;
}
Here we use the interface as the type of the object to show
polymorphism with mixin happeni
Right, I see what u are asking now.
Well, if you want to do Mixins in Vala, you'll have to do the "static"
workaround, since it doesn't support by default:

Now you want to do Mixing with Generics? Ok, add the generic
Hello,
of course I made mistake in my code.
I want to do interface that acts as a mixin, which will be mixed into class
specifies generic type, and I want methods from this mixin return the same
type as class that embeds the mixin.
Now I create interface with generic type, so in the parent class
Hey Marcin,
What is exactly you need from interfaces in your code ?Are you doing
Dependency Inversion?

Is not valid code. Interfaces should "derive" from Object. Interfaces list
dependencies, the first one should be Object, then other interfaces depends
on, the order matters, because if other interfaces depends on same, they
should be added first.
For your question, use typeof(G)

I don't know if your code is valid Vala. MyInterface should not inherit
MyClass.

Hello,
I am planning to use interfaces as in vspec as they are nice syntax sugar
for my purpose.
However, in order to make it working properly, I need to access type
defined as generic in the parent class implementing interface. Something
like
public interface MyIface : MyClass {
public MyGene
