public class Trace2targetMatcher extends org.eclipse.viatra.query.runtime.api.impl.BaseMatcher<Trace2targetMatch>
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 Trace2targetMatch
.
