TransactionSequence Class Reference
from PyKDE4.akonadi import *
Inherits: Akonadi.Job
Namespace: Akonadi
Detailed Description
Base class for jobs that need to run a sequence of sub-jobs in a transaction.
As soon as the first subjob is added, the transaction is started. As soon as the last subjob has successfully finished, the transaction is committed. If any subjob fails, the transaction is rolled back.
Alternatively, a TransactionSequence object can be used as a parent object for a set of jobs to achieve the same behaviour without subclassing.
