Fields Summary

Constructors Summary
protected EJBQueryImpl(EntityManagerImpl entityManager) Base constructor for EJBQueryImpl. Initializes basic variables. An EJBQLQueryImpl may only ever be tied to one entityManager. super(entityManager);
public EJBQueryImpl(DatabaseQuery query, EntityManagerImpl entityManager) Create an EJBQueryImpl with a TopLink query. param query param entityManager super(query, entityManager);
public EJBQueryImpl(String ejbql, EntityManagerImpl entityManager) Build an EJBQueryImpl based on the given ejbql string param ejbql param entityManager super(ejbql, entityManager);
public EJBQueryImpl(String queryDescription, EntityManagerImpl entityManager, boolean isNamedQuery) Create an EJBQueryImpl with either a query name or an ejbql string param queryDescription param entityManager param isNamedQuery determines whether to treat the query description as ejbql or a query name super(queryDescription, entityManager, isNamedQuery);
