ViatraQueryMatcher<ComplexFollowsTransitionMatch>

public class ComplexFollowsTransitionMatcher
extends BaseMatcher<ComplexFollowsTransitionMatch>

Generated pattern matcher API of the org.eclipse.viatra.cep.core.engine.compiler.complexFollowsTransition 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 ComplexFollowsTransitionMatch.

Original source:

 pattern
 complexFollowsTransition(automaton : Automaton, transition : TypedTransition, eventPattern : ComplexEventPattern) {
        find complexTransition(automaton, transition, eventPattern, operator);
        neg find negativeTransition(transition);
        FOLLOWS(operator);

                                          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:

ViatraQueryException - if an error occurs during pattern matcher creation

No Reference:

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