public class TranslatedEventPatternMatcher extends org.eclipse.viatra.query.runtime.api.impl.BaseMatcher<TranslatedEventPatternMatch>
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 TranslatedEventPatternMatch
.

countMatches(EventPattern pEventPattern)
Returns the number of all matches of the pattern that conform to the given fixed values of some parameters.
|
void |
forEachMatch(EventPattern pEventPattern,
org.eclipse.viatra.query.runtime.api.IMatchProcessor<? super TranslatedEventPatternMatch> processor)
Executes the given processor on each match of the pattern that conforms to the given fixed values of some parameters.
|
boolean |
forOneArbitraryMatch(EventPattern pEventPattern,
org.eclipse.viatra.query.runtime.api.IMatchProcessor<? super TranslatedEventPatternMatch> processor)
Executes the given processor on an arbitrarily chosen match of the pattern that conforms to the given fixed values of some parameters.
|
java.util.Collection<TranslatedEventPatternMatch> |
getAllMatches(EventPattern pEventPattern)
Returns the set of all matches of the pattern that conform to the given fixed values of some parameters.
|
java.util.Set<EventPattern> |
getAllValuesOfeventPattern()
Retrieve the set of values that occur in matches for eventPattern.
|
TranslatedEventPatternMatch |
getOneArbitraryMatch(EventPattern pEventPattern)
Returns an arbitrarily chosen match of the pattern that conforms to the given fixed values of some parameters.
|
boolean |
hasMatch(EventPattern pEventPattern)
Indicates whether the given combination of specified pattern parameters constitute a valid pattern match,
under any possible substitution of the unspecified parameters (if any).
|
TranslatedEventPatternMatch |
newMatch(EventPattern pEventPattern)
Returns a new (partial) match.
