So on Java I like to implement an interface directly on a local variable like this for example.

private SensorEventListener sensorEventListener = new SensorEventListener() { @Override public void onSensorChanged(SensorEvent event) { //implement here } @Override public void onAccuracyChanged(Sensor sensor, int accuracy) { //implement here } };

So that later I can add that listener directly and be able to remove the listener afterwards.

I'm trying to achieve the same idea on Kotlin, to have a var that implement the interface, without having to define a new class that extents that.

Is it possible? What is the semantic?

You create an object the implements the interface, for your code, 

var sensorEventListener = object : SensorEventListener { override fun onSensorChanged(event : SensorEvent) { } override fun onAccuracyChanged(sensor : Sensor, accuracy : Int) { } }

Thanks, through your answer I was able to find the session in the documentation that explains this. kotlinlang.org/docs/reference/object-declarations.html
