public class OpaqueExpressionResultMatcher extends org.eclipse.viatra.query.runtime.api.impl.BaseMatcher<OpaqueExpressionResultMatch>
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 OpaqueExpressionResultMatch
.
Original source:
(if behavior = null then
null
else
behavior.ownedParameter->first()
endif)
@Surrogate(feature = "result")
@QueryExplorer(checked = false)

OpaqueExpression.behavior.ownedParameter(source, target); // XXX only first?
