• public void refresh(Object object, LockMode lockMode);
• public Object get(Class clazz, Serializable id, LockMode lockMode);
• public Object get(String entityName, Serializable id, LockMode lockMode);

SessionFactory:

• public void evict(Class persistentClass) throws HibernateException;
• public void evict(Class persistentClass, Serializable id) throws
