Constructor Detail

OpenJpaVendorAdapter

public OpenJpaVendorAdapter()
Method Detail

getPersistenceProvider

public javax.persistence.spi.PersistenceProvider getPersistenceProvider()
Description copied from interface: JpaVendorAdapter
Return the vendor-specific persistence provider.


getPersistenceProviderRootPackage

public String getPersistenceProviderRootPackage()
Description copied from interface: JpaVendorAdapter
Return the name of the persistence provider's root package (e.g. "oracle.toplink.essentials"). Will be used for excluding provider classes from temporary class overriding.

Specified by:
getPersistenceProviderRootPackage in interface JpaVendorAdapter
Overrides:
getPersistenceProviderRootPackage in class AbstractJpaVendorAdapter

getJpaPropertyMap

public Map getJpaPropertyMap()
Description copied from interface: JpaVendorAdapter
Return a Map of vendor-specific JPA properties, typically based on settings in this JpaVendorAdapter instance.

Note that there might be further JPA properties defined on the EntityManagerFactory bean, which might potentially override individual JPA property values specified here.

Specified by:
getJpaPropertyMap in interface JpaVendorAdapter
Overrides:
getJpaPropertyMap in class AbstractJpaVendorAdapter
Returns:
a Map of JPA properties, as as accepted by the standard JPA bootstrap facilities, or null or an empty Map if there are no such properties to expose
See Also:
Persistence.createEntityManagerFactory(String, java.util.Map), PersistenceProvider.createContainerEntityManagerFactory(javax.persistence.spi.PersistenceUnitInfo, java.util.Map)

determineDatabaseDictionary

protected String determineDatabaseDictionary(Database database)
Determine the OpenJPA database dictionary name for the given database.

Parameters:
database - the specified database
Returns:
the OpenJPA database dictionary name, or null if none found

getJpaDialect

public JpaDialect getJpaDialect()
Description copied from interface: JpaVendorAdapter
Return the vendor-specific JpaDialect implementation for this provider, or null if there is none.

Specified by:
getJpaDialect in interface JpaVendorAdapter
Overrides:
getJpaDialect in class AbstractJpaVendorAdapter

getEntityManagerFactoryInterface

public Class<? extends javax.persistence.EntityManagerFactory> getEntityManagerFactoryInterface()
Description copied from interface: JpaVendorAdapter
Return the vendor-specific EntityManagerFactory interface that the EntityManagerFactory proxy is supposed to implement.

If the provider does not offer any EntityManagerFactory extensions, the adapter should simply return the standard EntityManagerFactory class here.

Specified by:
getEntityManagerFactoryInterface in interface JpaVendorAdapter
Overrides:
getEntityManagerFactoryInterface in class AbstractJpaVendorAdapter

getEntityManagerInterface

public Class<? extends javax.persistence.EntityManager> getEntityManagerInterface()
Description copied from interface: JpaVendorAdapter
Return the vendor-specific EntityManager interface that this provider's EntityManagers will implement.

If the provider does not offer any EntityManager extensions, the adapter should simply return the standard EntityManager class here.

Specified by:
getEntityManagerInterface in interface JpaVendorAdapter
Overrides:
getEntityManagerInterface in class AbstractJpaVendorAdapter
