How to force derived class to call super method? (Like Android does)

Question

I was wondering, when creating new Activity classes and then overriding the onCreate() method, in eclipse I always get auto added: super.onCr

Answer 1

Here's the source of Activity#onCreate() - it is almost all comments (original - see line ~800):

/**
 * Called when the activity is starting.  This is where most initialization
 * should go: calling {@link #setContentView(int)} to inflate the
 * activity's UI, using {@link #findViewById} to programmatically interact
 * with widgets in the UI, calling
 * {@link #managedQuery(android.net.Uri , String[], String, String[], String)} to retrieve
 * cursors for data being displayed, etc.
 *
 * 
You can call {@link #finish} from within this function, in
 * which case onDestroy() will be immediately called without any of the rest
 * of the activity lifecycle ({@link #onStart}, {@link #onResume},
 * {@link #onPause}, etc) executing.
 *
 * 
Derived classes must call through to the super class's
 * implementation of this method.  If they do not, an exception will be
 * thrown.
 *
 * @param savedInstanceState If the activity is being re-initialized after
 *     previously being shut down then this Bundle contains the data it most
 *     recently supplied in {@link #onSaveInstanceState}.  Note: Otherwise it is null.
 *
 * @see #onStart
 * @see #onSaveInstanceState
 * @see #onRestoreInstanceState
 * @see #onPostCreate
 */
protected void onCreate(Bundle savedInstanceState) {
    mVisibleFromClient = !mWindow.getWindowStyle().getBoolean(
            com.android.internal.R.styleable.Window_windowNoDisplay, false);
    mCalled = true;
}

so, my guess would be that the ADT Eclipse plugin is what's auto-adding that call to super.onCreate() for you. It's a total guess, though.
