Can you explicitly call the super class when using interface delegation in Kotlin?












1















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)
          }
          }
