TransactionEvent

The TransactionEvent class is the superclass for all events in relation to transactions. A transaction processes actions generated from model and resource diffs. Thus, the events are usually in relation with these actions.

Warning

It is not a good practice to create an event from this class directly, but should rather create one from one of the subclasses. This promotes a more accurate classification of events.

@example

const myEvent = new TransactionEvent('MyActionName');
EventService.getInstance().emit(myEvent);

@returns

The Event instance.
