Self Method and field

Android sample of self method/impl self interface

//data module define
public interface TestSelfMethod extends TestSelfMethodWithImplInterface.TextDelegate, DataPools.Poolable {

   Property PROP_text = SharedProperties.get("java.lang.String", "text", 0);

   @Keep
   @ImplMethod(from = HelpUtil.class)
   void changeText(String text);

   TestSelfMethod setText(String text1);

   String getText();

   class HelpUtil {
       //compare to  ' void changeText(String text);' , just add a module param at the first.
       public static void changeText(TestSelfMethod module, String text) {
           //just mock text change.
           //module can be real data or data proxy, if is proxy it will auto dispatch text change= event.
           module.setText(text);
       }

   }
}

//sample activity
public class TestSelfMethodWithImplInterface extends BaseActivity {

   @BindView(R.id.textView)
   TextView mTv;

   private TestSelfMethod mProxy;
   @Override
   protected int getLayoutId() {
       return R.layout.ac_self_methods;
   }

   @Override
   protected void onInit(Context context, Bundle savedInstanceState) {
       Binder<TestSelfMethod> binder = DataMediatorFactory.createBinder(TestSelfMethod.class);
       //bind property to textView
       binder.bindText(TestSelfMethod.PROP_text, mTv);
       //get proxy
       mProxy = binder.getDataProxy();
   }

   @OnClick(R.id.button)
   public void onClickCallSelf(View view){
       //call self method
       mProxy.changeText("text changed: " + System.currentTimeMillis());
   }
