Can you explicitly call the super class when using interface delegation in Kotlin?
I using interface delegation as described here. Is there a way to use this but override and explicitly call the super class (delegate)?
Something along these lines (does not compile):
class Rect(val width: Int, val height: Int, position: Position) : Positionable by DefaultPositionable(position) {
override fun getPosition() {
val parent = super.getPosition()
return parent.copy(x = parent.x + 1)
}
}

You can't access delegate
in that case. As workaround you can use next approach
class Rect(
val width: Int,
val height: Int,
val pos: Position,
private val positinable: Positionable = DefaultPositionable(pos)
) : Positionable by positinable {
override fun getPosition(): Position {
val parent = positinable.getPosition()
return parent.copy(x = parent.x + 1)
}
}
