Method Detail

newTree

public QueryTree newTree()

Returns a new QueryTree instance. This instance allows to specify a query with an API (see QueryTree and ExpressionFactory) rather than as JDOQL strings. To run you create a query object from the QueryTree (see PersistenceManager.newQuery(Object compiled)) and call the execute method on the Query object.

Specified by:

newTree in interface JDOQLQueryFactory

Returns:

new QueryTree instance.

newQuery

public javax.jdo.Query newQuery(org.apache.jdo.pm.PersistenceManagerInternal pm)

Description copied from interface: JDOQLQueryFactory

Creates a new Query with no elements.

Specified by:

newQuery in interface JDOQLQueryFactory

Parameters:

pm - the persistence manager for the new query. It is the responsibility of the caller to check that the persistence manager is valid.

Returns:

the new Query.

newQuery

public javax.jdo.Query newQuery(org.apache.jdo.pm.PersistenceManagerInternal pm,
                                java.lang.Object compiled)

Description copied from interface: JDOQLQueryFactory

Creates a new Query using elements from another Query. The other Query must have been created by the same JDO implementation. It might be active in a different PersistenceManager or might have been serialized and restored.

All of the settings of the other Query are copied to this Query, except for the candidate Collection or Extent.

Specified by:

newQuery in interface JDOQLQueryFactory

Parameters:

pm - the persistence manager for the new query. It is the responsibility of the caller to check that the persistence manager is valid.

compiled - another Query from the same JDO implementation.

Returns:

the new Query.

newQuery

public javax.jdo.Query newQuery(org.apache.jdo.pm.PersistenceManagerInternal pm,
                                java.lang.Class cls)

Description copied from interface: JDOQLQueryFactory

Creates a new Query specifying the Class of the candidate instances.

Specified by:

newQuery in interface JDOQLQueryFactory

Parameters:

pm - the persistence manager for the new query. It is the responsibility of the caller to check that the persistence manager is valid.

cls - the Class of the candidate instances.

Returns:

the new Query.

newQuery

public javax.jdo.Query newQuery(org.apache.jdo.pm.PersistenceManagerInternal pm,
                                javax.jdo.Extent cln)

Description copied from interface: JDOQLQueryFactory

Creates a new Query with the Class of the candidate instances and candidate Extent.

Specified by:

newQuery in interface JDOQLQueryFactory

Parameters:

pm - the persistence manager for the new query. It is the responsibility of the caller to check that the persistence manager is valid.

cln - the Extent of candidate instances.

Returns:

the new Query.

newQuery

public javax.jdo.Query newQuery(org.apache.jdo.pm.PersistenceManagerInternal pm,
                                java.lang.Class cls,
                                java.util.Collection cln)

Description copied from interface: JDOQLQueryFactory

Creates a new Query with the candidate Class and Collection.

Specified by:

newQuery in interface JDOQLQueryFactory

Parameters:

pm - the persistence manager for the new query. It is the responsibility of the caller to check that the persistence manager is valid.

cls - the Class of results.

cln - the Collection of candidate instances.

Returns:

the new Query.

                                java.lang.String filter)

Description copied from interface: JDOQLQueryFactory

Creates a new Query with the Class of the candidate instances and filter.

Specified by:

newQuery in interface JDOQLQueryFactory

Parameters:
