Class HibernateUtil

java.lang.Object
  net.sf.hibernate4gwt.core.hibernate.HibernateUtil

All Implemented Interfaces:

IPersistenceUtil

public class HibernateUtil
extends java.lang.Object
implements IPersistenceUtil

Persistent helper for Hibernate implementation Centralizes the SessionFactory and add some needed methods. Not really a singleton, since there can be as many HibernateUtil instance as different sessionFactories
