Examples of org.hibernate.Query.iterate()

org.hibernate.Query.iterate()
Return the query results as an Iterator. If the query contains multiple results pre row, the results are returned in an instance of Object[].

Entities returned as results are initialized on demand. The first SQL query returns identifiers only.
@return the result iterator @throws HibernateException
