ActionBarSherlock (HoloEverywhere Library 1.4.0 API)

java.lang.Object
- com.actionbarsherlock.ActionBarSherlock

Direct Known Subclasses:

ActionBarSherlockCompat, ActionBarSherlockNative
```
public abstract class ActionBarSherlock
extends Object
```
Helper for implementing the action bar design pattern across all versions of Android.

This class will manage interaction with a custom action bar based on the Android 4.0 source code. The exposed API mirrors that of its native counterpart and you should refer to its documentation for instruction.
