Interface EntityManagerFactoryInfo

All Known Implementing Classes:

AbstractEntityManagerFactoryBean, LocalContainerEntityManagerFactoryBean, LocalEntityManagerFactoryBean

public interface EntityManagerFactoryInfo

Metadata interface for a Spring-managed JPA EntityManagerFactory.

This facility can be obtained from Spring-managed EntityManagerFactory proxies through casting the EntityManagerFactory handle to this interface.

Since:

2.0

Method Summary

ClassLoader	getBeanClassLoader() Return the ClassLoader that the application's beans are loaded with.
DataSource	getDataSource() Return the JDBC DataSource that this EntityManagerFactory obtains its JDBC Connections from.
Class<? extends EntityManager>	getEntityManagerInterface() Return the (potentially vendor-specific) EntityManager interface that this factory's EntityManagers will implement.
JpaDialect	getJpaDialect() Return the vendor-specific JpaDialect implementation for this EntityManagerFactory, or null if not known.
EntityManagerFactory	getNativeEntityManagerFactory() Return the raw underlying EntityManagerFactory.
PersistenceProvider	getPersistenceProvider() Return the underlying PersistenceProvider that the underlying EntityManagerFactory was created with.
PersistenceUnitInfo	getPersistenceUnitInfo() Return the PersistenceUnitInfo used to create this EntityManagerFactory, if the in-container API was used.
String	getPersistenceUnitName() Return the name of the persistence unit used to create this EntityManagerFactory, or null if it is an unnamed default.

Method Detail

getNativeEntityManagerFactory

EntityManagerFactory getNativeEntityManagerFactory()

Return the raw underlying EntityManagerFactory.

Returns:

the unadorned EntityManagerFactory (never null)

getPersistenceProvider

PersistenceProvider getPersistenceProvider()

Return the underlying PersistenceProvider that the underlying EntityManagerFactory was created with.

Returns:

the PersistenceProvider used to create this EntityManagerFactory, or null if the standard JPA provider autodetection process was used to configure the EntityManagerFactory

getPersistenceUnitInfo

PersistenceUnitInfo getPersistenceUnitInfo()

Return the PersistenceUnitInfo used to create this EntityManagerFactory, if the in-container API was used.

Returns:

the PersistenceUnitInfo used to create this EntityManagerFactory, or null if the in-container contract was not used to configure the EntityManagerFactory

getPersistenceUnitName

String getPersistenceUnitName()

Return the name of the persistence unit used to create this EntityManagerFactory, or null if it is an unnamed default.

If getPersistenceUnitInfo() returns non-null, the result of getPersistenceUnitName() must be equal to the value returned by PersistenceUnitInfo.getPersistenceUnitName().

See Also:

getPersistenceUnitInfo(), PersistenceUnitInfo.getPersistenceUnitName()

getDataSource

DataSource getDataSource()

Return the JDBC DataSource that this EntityManagerFactory obtains its JDBC Connections from.

Returns:

the JDBC DataSource, or null if not known

getEntityManagerInterface

Class<? extends EntityManager> getEntityManagerInterface()

Return the (potentially vendor-specific) EntityManager interface that this factory's EntityManagers will implement.

A null return value suggests that autodetection is supposed to happen: either based on a target EntityManager instance or simply defaulting to javax.persistence.EntityManager.

getJpaDialect

JpaDialect getJpaDialect()

Return the vendor-specific JpaDialect implementation for this EntityManagerFactory, or null if not known.

getBeanClassLoader

ClassLoader getBeanClassLoader()

Return the ClassLoader that the application's beans are loaded with.

Proxies will be generated in this ClassLoader.
