Have gone through the official docs and some tutorials online but still quite unsure where and when to use Interface Delegation. When do you use Interface Delegation in your projects? 🤔 Examples and instances would be greatly appreciated. 🙏🏾

i use it when i want to compose classes of multiple objects ie common and specifics

data class ComposedComponent(
   val common: Common,
   val specific: SpecificComponent
): ICommon by common, ISpecific by specific

it saves typing and making copypaste errors sadly it does not flatten it magically inside serialization

Here’s a real world example I had: https://blog.lidalia.org.uk/2020/05/kotlin-intersection-types.html

Use inheritance when you will reference the interface (List, MutableList etc). Else use composition
