Interface TriggerChangeEvent

All Known Implementing Classes:

InventoryGRN

public interface TriggerChangeEvent

A marker interface to denote that the StoredObject class that implements this will trigger an event when a change is made to its instance data. The event is captured by the platform's internal event management system and is made available for further processing. The change event is triggered only when the changes are saved to the database.

Typically, the change is passed to a DataChangeNotifier once the transaction is committed. A DataChangeNotifier can be registered with the platform by defining an entry in the DataChangeNotifierLogic.

The DataChangeNotifier receives the changes as a list of DataChanged instances.
