Method Detail

createEntityManagerFactory

public OpenJPAEntityManagerFactory createEntityManagerFactory(java.lang.String name,
                                                              java.lang.String resource,
                                                              java.util.Map m)

Loads the entity manager specified by name, applying the properties in m as overrides to the properties defined in the XML configuration file for name. If name is null, this method loads the XML in the resource identified by resource, and uses the first resource found when doing this lookup, regardless of the name specified in the XML resource or the name of the jar that the resource is contained in. This does no pooling of EntityManagersFactories.

Returns:

EntityManagerFactory or null

createEntityManagerFactory

public OpenJPAEntityManagerFactory createEntityManagerFactory(java.lang.String name,
                                                              java.util.Map m)

Specified by:

createEntityManagerFactory in interface jakarta.persistence.spi.PersistenceProvider

createContainerEntityManagerFactory

public OpenJPAEntityManagerFactory createContainerEntityManagerFactory(jakarta.persistence.spi.PersistenceUnitInfo pui,
                                                                       java.util.Map m)

Specified by:

createContainerEntityManagerFactory in interface jakarta.persistence.spi.PersistenceProvider

generateSchema

public void generateSchema(jakarta.persistence.spi.PersistenceUnitInfo info,
                           java.util.Map map)

Specified by:

generateSchema in interface jakarta.persistence.spi.PersistenceProvider

generateSchema

public boolean generateSchema(java.lang.String persistenceUnitName,
                              java.util.Map map)

Specified by:

generateSchema in interface jakarta.persistence.spi.PersistenceProvider

acceptProvider

public boolean acceptProvider(java.util.Map properties)

setPersistenceEnvironmentInfo

public void setPersistenceEnvironmentInfo(OpenJPAConfiguration conf,
                                          jakarta.persistence.spi.PersistenceUnitInfo pui)

getProviderUtil

public jakarta.persistence.spi.ProviderUtil getProviderUtil()

Specified by:

getProviderUtil in interface jakarta.persistence.spi.PersistenceProvider

getDefaultBrokerAlias

protected java.lang.String getDefaultBrokerAlias()

newConfigurationImpl

protected OpenJPAConfiguration newConfigurationImpl()

isLoaded

public jakarta.persistence.spi.LoadState isLoaded(java.lang.Object obj)

Determines whether the specified object is loaded.

Specified by:

isLoaded in interface jakarta.persistence.spi.ProviderUtil

Returns:

LoadState.LOADED - if all implicit or explicit EAGER fetch attributes are loaded LoadState.NOT_LOADED - if any implicit or explicit EAGER fetch attribute is not loaded LoadState.UNKNOWN - if the entity is not managed by this provider.

isLoadedWithReference

public jakarta.persistence.spi.LoadState isLoadedWithReference(java.lang.Object obj,
                                                               java.lang.String attr)

Determines whether the attribute on the specified object is loaded. This method may access the value of the attribute to determine load state (but currently does not).

Specified by:

isLoadedWithReference in interface jakarta.persistence.spi.ProviderUtil

Returns:

LoadState.LOADED - if the attribute is loaded. LoadState.NOT_LOADED - if the attribute is not loaded or any EAGER fetch attributes of the entity are not loaded. LoadState.UNKNOWN - if the entity is not managed by this provider or if it does not contain the persistent attribute.

isLoadedWithoutReference

public jakarta.persistence.spi.LoadState isLoadedWithoutReference(java.lang.Object obj,
                                                                  java.lang.String attr)

Determines whether the attribute on the specified object is loaded. This method does not access the value of the attribute to determine load state.

Specified by:

isLoadedWithoutReference in interface jakarta.persistence.spi.ProviderUtil

Returns:

LoadState.LOADED - if the attribute is loaded. LoadState.NOT_LOADED - if the attribute is not loaded or any EAGER fetch attributes of the entity are not loaded. LoadState.UNKNOWN - if the entity is not managed by this provider or if it does not contain the persistent attribute.
