Communicate with a fragment in a FragmentTabHost

I want to communicate with a fragment in a FragmentTabHost

The communication Fragment->Activity is done! With an interface.

But I can't create a communication Activity->Fragment because I created the fragment like this:

mTabHost.addTab(
            mTabHost.newTabSpec("tab2").setIndicator("Affichage",
                    getResources().getDrawable(android.R.drawable.star_on)),
            MySelectionFragment.class, null);

MySelectionFragment is a class not a fragment like new MySelectionFragment()

And I dunno how to communicate with a class :/

Thanks in advance!

The trick was to override the onAttach method like this:

@Override
public void onAttachFragment(android.support.v4.app.Fragment attachedFragment) {
    super.onAttachFragment(attachedFragment);

    if (attachedFragment.getClass().equals((ObjectA.class)) {
        mObjectA = (ObjectA)attachedFragment;
    }
    if (attachedFragment.getClass().equals((ObjectB.class)) {
        mObjectB = (ObjectB) attachedFragment;
    }
}
