Method Details

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
