All Implemented Interfaces:

ViatraQueryMatcher<EnabledNegativeTransitionMatch>

public class EnabledNegativeTransitionMatcher
extends BaseMatcher<EnabledNegativeTransitionMatch>

Generated pattern matcher API of the org.eclipse.viatra.cep.core.engine.runtime.enabledNegativeTransition pattern, providing pattern-specific query methods.

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 EnabledNegativeTransitionMatch.

Original source:

 pattern enabledNegativeTransition(transition : NegativeTransition, eventToken : EventToken, event : Event, automaton : Automaton) {
        find latestEvent(event);
        Event.type(event, eventType);
        neg find transitionWithEventType(transition, eventType);
        NegativeTransition.preState.eventTokens(transition, eventToken);
        neg find eventProcessedByEventToken(event, eventToken);
        
        Automaton.states(automaton, state);
        State.outTransitions(state, transition);
 }

                                           throws ViatraQueryException

Initializes the pattern matcher within an existing VIATRA Query engine. If the pattern matcher is already constructed in the engine, only a light-weight reference is returned. The match set will be incrementally refreshed upon updates.

Parameters:

engine - the existing VIATRA Query engine in which this matcher will be created.

Throws:

ViatraQueryException - if an error occurs during pattern matcher creation

create

                                               throws ViatraQueryException

Returns:

an initialized matcher

Throws:

No Reference:

This method is for internal matcher initialization by the framework, do not call it manually.
