Android FragmentStatePagerAdapter, how to tag a fragment to find it later

When using the FragmentStatePageAdapter I get the fragments like this:

    @Override
    public Fragment getItem(int position) {
        return new SuperCoolFragment();
    }

However, later on my code I need to find this fragment to set a property. In some other parts of the app where I use fragments I basically tag them and look for them using findFragmentByTag(TAG) but with now I don't know how to do it.

How do can I find the fragments using the FragmentStatePageAdapter?
