public class EventProcessedByEventTokenMatcher extends org.eclipse.viatra.query.runtime.api.impl.BaseMatcher<EventProcessedByEventTokenMatch>
Use the pattern matcher on a given model via on(ViatraQueryEngine)
,
e.g. in conjunction with ViatraQueryEngine#on(Notifier)
.
Matches of the pattern will be represented as EventProcessedByEventTokenMatch
.
Original source:
pattern eventProcessedByEventToken(event : Event, eventToken : EventToken) {
EventToken.lastProcessed(eventToken, event);
