How to call outer class' super method from inner class in Kotlin?

Issue

What is the Kotlin equivalent of Java's OuterClass.super.method()?

Example (in Java):

class Outer {
    class Inner {
        void someMethod() {
            Outer.super.someOtherMethod();
        }
    }

    @Override
    public String someOtherMethod() {
        // This is not called...
    }
}

Solution

Use the [email protected]() syntax:

open class C {
    open fun f() { println("C.f()") }
}

class D : C() {
    override fun f() { println("D.f()") }

    inner class X {
        fun g() {
            [email protected]() // <- here
        }
    }
}

This is similar to how Java OuterClass.this is expressed in Kotlin as this@OuterClass.
