Constructor Detail

### QueryImpl

    public QueryImpl(String queryString,
                     FlushMode flushMode,
                     SessionImplementor session,
                     ParameterMetadata parameterMetadata)

### QueryImpl

    public QueryImpl(String queryString,
                     SessionImplementor session,
                     ParameterMetadata parameterMetadata)

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 `ResultSet`s.

  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 `ResultSet`s.

  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`
