             throws org.hibernate.HibernateException,
                    java.sql.SQLException

Method Detail

close

public void close()
           throws org.hibernate.JDBCException

Specified by:

close in interface org.hibernate.engine.HibernateIterator

---

postNext

private void postNext()
               throws org.hibernate.HibernateException,
                      java.sql.SQLException

---

hasNext

public boolean hasNext()

Description copied from interface: java.util.Iterator

Tests whether there are elements remaining in the collection. In other words, calling next() will not throw an exception.

Specified by:

hasNext in interface java.util.Iterator

---

next

public java.lang.Object next()

Description copied from interface: java.util.Iterator

Obtain the next element in the collection.

Specified by:

next in interface java.util.Iterator

---

remove

public void remove()

Description copied from interface: java.util.Iterator

Remove from the underlying collection the last element returned by next (optional operation). This method can be called only once after each call to next(). It does not affect what will be returned by subsequent calls to next.

Specified by:
