Method Detail

createNewEntityManager

public static javax.persistence.EntityManager createNewEntityManager()

closeEMF

public static Boolean closeEMF()

closeEMF

public static Boolean closeEMF(boolean suppressListener)

initBeforeMigration

public static void initBeforeMigration()

Initializes the EMProvider for migration. This method should be called before the migration starts. Migration refers to the process of changing the encryption key used for the application layer encryption.

initAfterMigration

public static void initAfterMigration()

Re-initializes the EMProvider after a migration. This method should be called after the migration finishes. Migration refers to the process of changing the encryption key used for the application layer encryption.

markEntityForMigration

public static void markEntityForMigration(javax.persistence.EntityManager em,
                                          Object entity)

Marks the entity for migration. Only one entity can be marked at a time. The marking is associated with the given entity manager session. The marking is bound to the lifetime of the session, i.e. it is removed when the session is closed.

Implementation note: This is needed to convince hibernate to persist an entity to the database even though none of its fields have changed. We read the entity with the old encryption key and write it back with the new encryption key.

Parameters:

em - The entity manager representing the session.

entity - The class to mark for migration. Removes the marking when null.
