All known Subclasses: org.objectweb.speedo.query.jdo.JDOQueryResultList, org.objectweb.speedo.query.jdo.JDOQueryResultUnique,
| JDOQueryResultCommon | | public class JDOQueryResultCommon (Code) | | Is a common classes used for compute the query result. This implementation
supports user class or persistent class as query result.

| Field Summary | |
| protected Object[] | conns
The underlying connection used to evalue the query. | | protected boolean | debug
| | protected Logger | logger
| | protected PersistenceManager | pm
The po manager representing the current execution context. | | protected TupleCollection | tc
|
| Constructor Summary | |
| public | JDOQueryResultCommon(TupleCollection _tc, PersistenceManager _pm, Object[] _conns, Class _resultClazz, Class[] _selectedFieldTypes, boolean staticFirstElementIndex, boolean returnIdentifierOnly, Logger _logger)
Builds a QueryResultList. |
| Method Summary | |
| public void | close()
Close the connection to the data store. | | public static void | closeConnection(Object conn)
| | protected Object | getValue(Tuple tuple)
When the array #selectedFieldTypes contains a single element, the result
of the query can or cannot be encapsulated into a user class. | | protected Object | pname2Object(PName pn)
|
| conns | | protected Object[] conns(Code) | | The underlying connection used to evalue the query. These connections
will be closed when the result will be no more used.
|
| debug | | protected boolean debug(Code) | | |
| logger | | protected Logger logger(Code) | | |
| pm | | protected PersistenceManager pm(Code) | | The po manager representing the current execution context. The
persistenceManager is used to fetch the real object from the identifier.
|
| tc | | protected TupleCollection tc(Code) | | The inner medor TupleCollection

| JDOQueryResultCommon | | public JDOQueryResultCommon(TupleCollection _tc, PersistenceManager _pm, Object[] _conns, Class _resultClazz, Class[] _selectedFieldTypes, boolean staticFirstElementIndex, boolean returnIdentifierOnly, Logger _logger) throws MedorException, SpeedoException(Code) | | Builds a QueryResultList.
Parameters:
_tc - the tuple collection representing the query result
Parameters:
_pm - is the peristence manager linked to the query
Parameters:
_conns - is the connection to the underlying support to close in same time than the query.
Parameters:
_resultClazz - is the class encapsulated the result |
| close | | public void close()(Code) | | Close the connection to the data store. The query result will be no
more usable after.
|
| closeConnection | | public static void closeConnection(Object conn)(Code) | | |
| getValue | | protected Object getValue(Tuple tuple) throws MedorException(Code) | | When the array #selectedFieldTypes contains a single element, the result
of the query can or cannot be encapsulated into a user class. When this
array contains several
element and the #resultClass field is not definied, the
Parameters:
tuple - contains the result the query result |
| pname2Object | | protected Object pname2Object(PName pn)(Code) | | Fetch the persistent instance corresponding to an identifier
Parameters:
pn - is the persistent object identifier a persistent instance if it has been found, otherwise a null value. |
