public final class EntityTransaction:
EntityTransaction

Transaction state owned by one EntityManager.

Provider work is delegated through callbacks created by the manager. This keeps transaction state provider-neutral while preserving a single public transaction API.

transaction = manager.transaction
transaction.begin()
try:
manager.saveChanges()
transaction.commit()
catch error as Exception:
transaction.rollback()
throw error
