How to extend a java.lang.runnable to be used in a thread?

[xulihang]

I checked this article: https://docs.nativescript.org/advanced-concepts.html#extend-classes-and-interfaces

But I cannot extend a runnable to be used in a thread.

Sample code:

@Interfaces([java.lang.Runnable]) /* the interfaces that will be inherited by the resulting MyVersatileCopyWriter class */
class DecodingRunnable extends java.lang.Object { 
  constructor() {
    super();
    console.log("runnable");
    return global.__native(this);
  }

  run() {
    console.log("run");
  }
}

To use it:

let runnable:java.lang.Runnable = new DecodingRunnable();
let decodeThread = new java.lang.Thread(runnable);
decodeThread.start();

It seems that I need to add the NativeClass decorator.

@NativeClass
class DecodingRunnable extends java.lang.Runnable {
  constructor(reader,frame){
    super();
    console.log("constructor");
    return global.__native(this);
  }

  run() {
    console.log("run");

  }
}
