I can't quite understand what this syntax is: ``` private val surfaceTextureListener = object : ...

# android

I can't quite understand what this syntax is:

private val surfaceTextureListener = object : TextureView.SurfaceTextureListener {

        override fun onSurfaceTextureAvailable(texture: SurfaceTexture, width: Int, height: Int) {
        //...
    }

It’s creation of object

[gildor]

like creation of anonymous class in Java

[Willy Njundong]

Aw man, I never got that far with Java. Only basic classes.

[gildor]

Java analogue would be:

new TextureView.SurfaceTextureListener {
   @Override
   void  onSurfaceTextureAvailable(…)
}

Can you link me to relevant kotlin docs that might give me more insight
