Question

In my base class I have

  trait EventReceiver  {

    def onStart(start: Start) {

    }

  }

I define

  def benchmark = new EventReceiver {}

since I need to do some processing in the base class. In the child class which my clients use they do something similar to the following

override def benchmark = new EventReceiver {
    override def onStart(start: Start) {
      println("benchmark start")
    }
}

I view this bit as a bit clunky

override def benchmark = new EventReceiver { ...

Is there a nicer way to express this? Ideally it would be something like

singleword {
    override def onStart(start: Start) {
      println("benchmark start")
    }
}

Answer 1

For example,

def singleword(fOnStart: Start => Unit) =
  new EventReceiver {
    override def onStart(start: Start) { fOnStart(start) }
  }

then,

singleword { start =>
  println("benchmark started")
}
