How does the container get passed to a fragment?

I'm attempting to understand someone else's code. They are using fragments (which I'm rather hazy on).

I know that a fragment starts up with onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState .. but I can't fathom where the "container" was set up.

where should I look?

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    v = inflater.inflate(R.layout.news_list, container, false);
    return v;
}

The layout news_list is for this fragment.

container is handled by the Android framework, it typically refers to View passed by id in methods like FragmentTransaction's add(int containerViewId, Fragment fragment) or replace(int containerViewId, Fragment fragment).

For example, this is from the Developer's Guide:

ExampleFragment fragment = new ExampleFragment();
fragmentTransaction.add(R.id.fragment_container, fragment);
fragmentTransaction.commit();
