Is it possible to access the tabs when writing a custom TabbedRenderer for Android?

I'm trying to access the tabs of the action bar to modify them as shown in the Java code below. Is it possible by creating my own renderer? I checked all members of TabbedRenderer but haven't seen anything that would allow me to get to the tabs.

tab = getActionBar.newTab();
tab.setText(tabText);
tab.setIcon(R.drawable.tab_icon);
