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

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