Constructor Detail

CriteriaQuery

public CriteriaQuery(org.datanucleus.store.StoreManager storeMgr,
                     org.datanucleus.ExecutionContext ec)

Constructs a new query instance that uses the given persistence manager.

Parameters:

storeMgr - StoreManager for this query

ec - execution context

CriteriaQuery

public CriteriaQuery(org.datanucleus.store.StoreManager storeMgr,
                     org.datanucleus.ExecutionContext ec,
                     Object criteriaQuery)

Constructor for a query using NeoDatis "native" query language. The second parameter must implement "org.neodatis.odb.impl.core.query.criteria.CriteriaQuery".

Parameters:
