98 | isLoaded(entity)Method javax.persistence.PersistenceUnitUtil boolean isLoaded( Object entity ) Determine the load state of an entity belonging to the persistence unit. This method can be used to determine the load state of an entity passed as a reference. An entity is considered loaded if all attributes |
98 | isLoaded(entity, attributeName)Method javax.persistence.PersistenceUnitUtil boolean isLoaded( Object entity, String attributeName ) Determine the load state of a given persistent attribute of an entity belonging to the persistence unit. Parameters: entity - entity instance containing the attribute attributeName - name |
98 | javax.persistence.PersistenceUnitUtiljavax.persistence Interface PersistenceUnitUtil Superinterfaces: PersistenceUtil Utility interface between the application and the persistence provider managing the persistence unit. The methods of this interface should only be invoked on entity instances obtained from or managed by entity managers |
98 | getIdentifier(entity)Method javax.persistence.PersistenceUnitUtil Object getIdentifier( Object entity ) Return the id of the entity. A generated id is not guaranteed to be available until after the database insert has occurred. Returns null if the entity does not yet have an id. Parameters: entity - entity instance |
42 | JPA Primary Key key) of a specified managed entity object. For example: PersistenceUnitUtil util = emf.getPersistenceUnitUtil(); Object projectId = util.getIdentifier(project); A PersistenceUnitUtil instance |
30 | JPA MiscellaneousThis section contains miscellaneous JPA types. The PersistenceUtil and PersistenceUnitUtil interfaces provide general utility methods: The Cache interface and the CacheRetrieveMode and CacheStoreMode enum types serve in managing the EntityManagerFactory's shared (level 2) cache: Other enum types are provided for setting of various JPA operations: |
15 | EntityManager refresh problem.persistence.PersistenceUnitUtil; import org.junit.Assert; import org.junit.Test; import entities |
12 | javax.persistence.EntityManagerFactory.0 PersistenceUnitUtil getPersistenceUnitUtil() Return interface providing access to utility methods ... unit. Returns: PersistenceUnitUtil interface Throws: IllegalStateException - if the entity manager |
12 | getPersistenceUnitUtil()Method javax.persistence.EntityManagerFactory PersistenceUnitUtil getPersistenceUnitUtil() Return interface providing access to utility methods for the persistence unit. Returns: PersistenceUnitUtil interface Throws: IllegalStateException - if the entity manager factory has been closed Since: JPA 2.0 |
9 | javax.persistence.PersistenceUtiljavax.persistence Interface PersistenceUtil Subinterfaces: PersistenceUnitUtil Utility interface between the application and the persistence provider(s). The PersistenceUtil interface instance obtained from the Persistence class is used to determine the load state of an entity or entity attribute |
