public class CounterUtil
extends Object

The persistence utility for the counter service. This utility wraps CounterPersistenceImpl and provides direct access to the database for CRUD operations. This utility should only be used by the service layer, as it must operate within a transaction. Never access this utility in a JSP, controller, model, or other front-end class.

the range of counters

Throws:

SystemException - if a system exception occurred
