Method Detail

iterate

public Iterator iterate()
                 throws HibernateException
Description copied from interface: Query
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.

Returns:
the result iterator
Throws:
HibernateException

scroll

public ScrollableResults scroll()
                         throws HibernateException
Description copied from interface: Query
Return the query results as ScrollableResults. The scrollability of the returned results depends upon JDBC driver support for scrollable ResultSets.

Returns:
the result iterator
Throws:
HibernateException
See Also:
ScrollableResults

scroll

public ScrollableResults scroll(ScrollMode scrollMode)
                         throws HibernateException
Description copied from interface: Query
Return the query results as ScrollableResults. The scrollability of the returned results depends upon JDBC driver support for scrollable ResultSets.

Returns:
the result iterator
Throws:
HibernateException
See Also:
ScrollableResults, ScrollMode

list

public List list()
          throws HibernateException
Description copied from interface: Query
Return the query results as a List. If the query contains multiple results pre row, the results are returned in an instance of Object[].

Returns:
the result list
Throws:
HibernateException

executeUpdate

public int executeUpdate()
                  throws HibernateException
Description copied from interface: Query
Execute the update or delete statement.

The semantics are compliant with the ejb3 Query.executeUpdate() method.

Returns:
The number of entities updated or deleted.
Throws:
HibernateException

setLockMode

public Query setLockMode(String alias,
                         LockMode lockMode)
Description copied from interface: Query
Set the lockmode for the objects idententified by the given alias that appears in the FROM clause.

Parameters:
alias - a query alias, or this for a collection filter

setLockOptions

public Query setLockOptions(LockOptions lockOption)
Description copied from interface: Query
Set the lock options for the objects idententified by the given alias that appears in the FROM clause.


getLockOptions

public LockOptions getLockOptions()
Specified by:
getLockOptions in class AbstractQueryImpl
