Re: [Vala] Is there any way to access generic type from the interface?

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

Re: [Vala] Is there any way to access generic type from the interface?

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

Re: [Vala] Is there any way to access generic type from the interface?

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

Re: [Vala] Is there any way to access generic type from the interface?

​​ 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: https://wiki.gnome.org/Projects/Vala/Tutorial#Mixins_and_Multiple_Inheritanae Now you want to do Mixing with Generics? Ok, add the

Re: [Vala] Is there any way to access generic type from the interface?

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

Re: [Vala] Is there any way to access generic type from the interface?

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) El feb. 27, 2016

Re: [Vala] Is there any way to access generic type from the interface?

I don't know if your code is valid Vala. MyInterface should not inherit MyClass. On Sat, Feb 27, 2016 at 10:59 mar...@saepia.net wrote: > 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

[Vala] Is there any way to access generic type from the interface?

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
