Interface CayenneEntityManager
- All Known Implementing Classes:
- JtaEntityManager, ResourceLocalEntityManager, TypeCheckingEntityManager
public interface CayenneEntityManager
An interface that allows to access Cayenne runtime hidden behind standard JPA classes.
To do that, simply cast an EntityManager returned by Cayenne provider to
"CayenneEntityManager". Note that a regular JPA application shouldn't normally attempt
to do that. Otherwise it will not be portable across JPA providers.
