public class PartiallyMatchedEventPatternMatcher extends BaseMatcher<PartiallyMatchedEventPatternMatch>
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 PartiallyMatchedEventPatternMatch
.
