setSynchronization(sync) - JDO Transaction's method

void setSynchronization(
  Synchronization sync

The user can specify a Synchronization instance to be notified on transaction completions. The beforeCompletion method is called prior to flushing instances to the data store.

The afterCompletion method is called after performing state transitions of persistent and transactional instances, following the data store commit or rollback operation.

Only one Synchronization instance can be registered with the Transaction. If the application requires more than one instance to receive synchronization callbacks, then the single application instance is responsible for managing them, and forwarding callbacks to them.
