```
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.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`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
```
@Nullable
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
```
@Nullable
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
```
@Nullable
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
```
@Nullable
DataSource getDataSource()
```
    Return the JDBC DataSource that this EntityManagerFactory obtains its JDBC Connections from.
    Returns:
    the JDBC DataSource, or null if not known
  - getEntityManagerInterface
```
@Nullable
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
```
@Nullable
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.
