Method Detail

determineJpaMetaModelPopulationSetting

protected org.hibernate.ejb.EntityManagerFactoryImpl.JpaMetaModelPopulationSetting determineJpaMetaModelPopulationSetting(Configuration cfg)

createEntityManager

public EntityManager createEntityManager()

Description copied from interface: EntityManagerFactory

Create a new application-managed EntityManager. This method returns a new EntityManager instance each time it is invoked. The isOpen method will return true on the returned instance.

Specified by:

createEntityManager in interface EntityManagerFactory

Returns:

entity manager instance

createEntityManager

public EntityManager createEntityManager(Map map)

Description copied from interface: EntityManagerFactory

Create a new application-managed EntityManager with the specified Map of properties. This method returns a new EntityManager instance each time it is invoked. The isOpen method will return true on the returned instance.

Specified by:

createEntityManager in interface EntityManagerFactory

Parameters:

map - properties for entity manager

Returns:

entity manager instance

getCriteriaBuilder

public CriteriaBuilder getCriteriaBuilder()

Description copied from interface: EntityManagerFactory

Return an instance of CriteriaBuilder for the creation of CriteriaQuery objects.

Specified by:

getCriteriaBuilder in interface EntityManagerFactory

Returns:

CriteriaBuilder instance

getMetamodel

public Metamodel getMetamodel()

Description copied from interface: EntityManagerFactory

Return an instance of Metamodel interface for access to the metamodel of the persistence unit.

Specified by:

getMetamodel in interface EntityManagerFactory

Returns:

Metamodel instance

close

public void close()

Description copied from interface: EntityManagerFactory

Close the factory, releasing any resources that it holds. After a factory instance has been closed, all methods invoked on it will throw the IllegalStateException, except for isOpen, which will return false. Once an EntityManagerFactory has been closed, all its entity managers are considered to be in the closed state.

Specified by:

close in interface EntityManagerFactory

getProperties

public Map<String,Object> getProperties()

Description copied from interface: EntityManagerFactory

Get the properties and associated values that are in effect for the entity manager factory. Changing the contents of the map does not change the configuration in effect.

Specified by:

getProperties in interface EntityManagerFactory

Returns:

properties

getCache

public Cache getCache()

Description copied from interface: EntityManagerFactory

Access the cache that is associated with the entity manager factory (the "second level cache").

Specified by:

getCache in interface EntityManagerFactory

Returns:

instance of the Cache interface

getPersistenceUnitUtil

public PersistenceUnitUtil getPersistenceUnitUtil()

Description copied from interface: EntityManagerFactory

Return interface providing access to utility methods for the persistence unit.

Specified by:

getPersistenceUnitUtil in interface EntityManagerFactory

Returns:

PersistenceUnitUtil interface

isOpen

public boolean isOpen()

Description copied from interface: EntityManagerFactory

Indicates whether the factory is open. Returns true until the factory has been closed.

Specified by:

isOpen in interface EntityManagerFactory

Returns:

boolean indicating whether the factory is open

getSessionFactory

public SessionFactory getSessionFactory()

Specified by:

getSessionFactory in interface HibernateEntityManagerFactory

getEntityManagerFactoryName

public String getEntityManagerFactoryName()
