Method Details

transactionFinished

public void transactionFinished(TransactionEvent e,
BackgroundTaskStatusProviderSupportingExternalCall status)

Description copied from interface: TransactionListener

Called when a transaction has stopped.
The class TransactionHashMap merges duplicate AttributeEvents. In case the Attribute path for the same Attributable is not equal, detailed information about Attribute path is lost. Instead a generic AttributeEvent containing just the Attributable is in the list of changed Objects (see TransactionEvent).
In case no detailed information about an Attribute change is available, your code should completely re-process the affected Attributable.
