Constructor Detail

JpaManagedObjectSource

public JpaManagedObjectSource()

Method Detail

beginTransaction

public static void beginTransaction(javax.persistence.EntityManager entityManager)

Begins the transaction on the EntityManager.

As OfficeFloor may manage the transaction for the EntityManager, it can not be begun. This enables beginning the transaction.

Parameters:

entityManager - EntityManager.

commitTransaction

public static void commitTransaction(javax.persistence.EntityManager entityManager)

Commits the transaction on the EntityManager.

As OfficeFloor may manage the transaction for the EntityManager, it can not be committed. This enables committing the transaction.

Parameters:

entityManager - EntityManager.

getConnection

public java.sql.Connection getConnection()

Obtains the Connection.

Returns:

Connection.

getPersistenceFactory

protected JpaManagedObjectSource.PersistenceFactory getPersistenceFactory(SourceContext context)
                                                                   throws java.lang.Exception

Obtains the JpaManagedObjectSource.PersistenceFactory.

Specific vendor implementations may override this method to specify the JpaManagedObjectSource.PersistenceFactory.

By default, this method uses the PROPERTY_PERSISTENCE_FACTORY Property to load the JpaManagedObjectSource.PersistenceFactory.

Parameters:

context - SourceContext.

Returns:

JpaManagedObjectSource.PersistenceFactory.

Throws:

java.lang.Exception - If fails to create the JpaManagedObjectSource.PersistenceFactory.

isRunWithinTransaction

protected boolean isRunWithinTransaction()

Indicates if required to run within EntityTransaction.

Returns:

true if required to run within EntityTransaction.

loadSpecification

protected void loadSpecification(AbstractAsyncManagedObjectSource.SpecificationContext context)

Description copied from class: AbstractAsyncManagedObjectSource

Overridden to load specifications.

Specified by:

loadSpecification in class AbstractAsyncManagedObjectSource<Indexed,None>

Parameters:

context - Specifications.

loadMetaData

protected void loadMetaData(AbstractAsyncManagedObjectSource.MetaDataContext<Indexed,None> context)
                     throws java.lang.Exception

Description copied from class: AbstractAsyncManagedObjectSource

Overridden to load meta-data.

Specified by:

loadMetaData in class AbstractAsyncManagedObjectSource<Indexed,None>

Parameters:

context - Meta-data.

Throws:

java.lang.Exception - If fails to load the meta-data.

getManagedObject

protected ManagedObject getManagedObject()
                                  throws java.lang.Throwable

Description copied from class: AbstractManagedObjectSource

Synchronously obtains the ManagedObject.

Specified by:

getManagedObject in class AbstractManagedObjectSource<Indexed,None>

Returns:

ManagedObject.

Throws:

java.lang.Throwable - If fails to obtain the ManagedObject.
