ClassyOpenHelperCallbacks Implementation of onCreate() and onUpdate() SQLiteOpenHelper abstract methods. This is a persistence container in which tasks can be performed using a supplied EntityManager object by calling doWork(). Unlike other PersistenceContainer implementations, the execution takes place in the current thread using supplied ConnectionSource to support ORMLite's special connection implementation. Any RuntimeException will be forwarded to the caller.
