ViatraQueryMatcher<Param2edgeMatch>

public class Param2edgeMatcher
extends BaseMatcher<Param2edgeMatch>

Generated pattern matcher API of the org.eclipse.viatra.addon.viewers.runtime.model.patterns.param2edge 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 Param2edgeMatch.

Original source:

  @QueryExplorer(checked = false)
 pattern param2edge(source, target, trace, edge : Edge) {
        Trace.params(trace, source);
        Trace.params(trace, target);
        Trace.targets(trace, edge);
 } or {
        Trace.objects(trace, source);
        Trace.params(trace, target);
        Trace.targets(trace, edge);
 } or {
        Trace.params(trace, source);
        Trace.objects(trace, target);
        Trace.targets(trace, edge);
 } or {

Method Detail

on

public static Param2edgeMatcher on(ViatraQueryEngine engine)
                            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.
