Annotate interface function that must call super

I'm creating interface and some function in it has a body.
It's required, that class that implements this interface must call super in overriding function before executing other code.
How can I do this?

interface Watcher {
fun funWithoutBody()

fun startWatching() {
//do some important stuff which must be called
}
}

You could just make `startWatching` abstract and call it in another function. E.g.:

interface Watcher {
fun funWithoutBody()

fun userDefinedStartWatching()

fun startWatching() {
//insert code you'd normally want to be called when using super()
userDefinedStartWatching()
}
}

Android Studio / IntelliJ IDEA does this sort of thing in some cases but it isn't done through annotations but through [code inspection][1].

e.g. `MissingSuperCall` is an [Android Lint Check][2] for which IntelliJ IDEA supports ([Integration with Android Lint tool in IntelliJ IDEA 11.1 | IntelliJ IDEA Blog][3]).

You can create your own custom inspection if you are using Android Studio or IntelliJ IDEA: [IntelliJ IDEA 2016.2 Help :: Creating Custom Inspections][4].

I've accidentally found, what I was looking for. It's a `@CallSuper` annotation available in `androidx.annotation` package. [Docs][1]

> Use the @CallSuper annotation to validate that an overriding method

> annotates the onCreate() method to ensure that any overriding method
> implementations call super.onCreate():

@CallSuper
protected fun onCreate(savedInstanceState: Bundle?) {
}
