Constructor Detail

EntityManagerFactoryImpl

public EntityManagerFactoryImpl(javax.persistence.spi.PersistenceUnitInfo puInfo,
                        Map<String,Object> properties)

EntityManagerFactoryImpl

public EntityManagerFactoryImpl(String persistenceUnit,
                        Map<String,Object> properties)

Use this if you want to construct this directly.

Parameters:

persistenceUnit - used to prefix the Cassandra domains

properties - the properties

Method Detail

configure

private void configure(String persistenceUnit,
             Map<String,Object> properties)

Parameters:

persistenceUnit -

properties -

close

public final void close()

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 javax.persistence.EntityManagerFactory

Throws:

IllegalStateException - if the entity manager factory has been closed

See Also:

EntityManagerFactory.close()

createEntityManager

public final javax.persistence.EntityManager createEntityManager()

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 javax.persistence.EntityManagerFactory

Returns:

entity manager instance

Throws:

IllegalStateException - if the entity manager factory has been closed

createEntityManager

public final javax.persistence.EntityManager createEntityManager(Map map)

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 javax.persistence.EntityManagerFactory

Parameters:

map - properties for entity manager

Returns:

entity manager instance

Throws:

IllegalStateException - if the entity manager factory has been closed

isOpen

public final boolean isOpen()

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

Specified by:

isOpen in interface javax.persistence.EntityManagerFactory

Returns:

boolean indicating whether the factory is open

See Also:

EntityManagerFactory.isOpen()

getCriteriaBuilder

public javax.persistence.criteria.CriteriaBuilder getCriteriaBuilder()

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

Specified by:

getCriteriaBuilder in interface javax.persistence.EntityManagerFactory

Returns:

CriteriaBuilder instance

Throws:

IllegalStateException - if the entity manager factory has been closed

See Also:

EntityManagerFactory.getCriteriaBuilder()

getMetamodel

public javax.persistence.metamodel.Metamodel getMetamodel()

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

Specified by:

getMetamodel in interface javax.persistence.EntityManagerFactory

Metamodel instance

Throws:

IllegalStateException - if the entity manager factory has been closed

See Also:

EntityManagerFactory.getMetamodel()

getProperties

public Map<String,Object> getProperties()

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 javax.persistence.EntityManagerFactory

Returns:

properties

Throws:

IllegalStateException - if the entity manager factory has been closed

See Also:

EntityManagerFactory.getProperties()

getCache

public javax.persistence.Cache getCache()

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

Specified by:
