All Implemented Interfaces:

IncQueryMatcher<ElementOwnerMatch>

public class ElementOwnerMatcher
extends BaseMatcher<ElementOwnerMatch>

Generated pattern matcher API of the org.eclipse.incquery.uml.derivedfeatures.elementOwner pattern, providing pattern-specific query methods.

Use the pattern matcher on a given model via on(IncQueryEngine), e.g. in conjunction with IncQueryEngine.on(Notifier).

Matches of the pattern will be represented as ElementOwnerMatch.

Original source:

  @Surrogate(feature = "owner")
  @QueryExplorer(checked = false)
 pattern elementOwner(source: Element, target: Element){
     // opposite of Element.ownedElement
     find elementOwnedElement(target, source);
 }

Constructor Detail

ElementOwnerMatcher

@Deprecated
public ElementOwnerMatcher(org.eclipse.emf.common.notify.Notifier emfRoot)
                                throws IncQueryException

Deprecated. use on(IncQueryEngine) instead, e.g. in conjunction with IncQueryEngine.on(Notifier)

Initializes the pattern matcher over a given EMF model root (recommended: Resource or ResourceSet). If a pattern matcher is already constructed with the same root, only a light-weight reference is returned. The scope of pattern matching will be the given EMF model root and below (see FAQ for more precise definition). The match set will be incrementally refreshed upon updates from this scope.

The matcher will be created within the managed IncQueryEngine belonging to the EMF model root, so multiple matchers will reuse the same engine and benefit from increased performance and reduced memory footprint.

Parameters:

emfRoot - the root of the EMF containment hierarchy where the pattern matcher will operate. Recommended: Resource or ResourceSet.

Throws:

IncQueryException - if an error occurs during pattern matcher creation

ElementOwnerMatcher

@Deprecated
public ElementOwnerMatcher(IncQueryEngine engine)
                                throws IncQueryException

Deprecated. use on(IncQueryEngine) instead

Initializes the pattern matcher within an existing EMF-IncQuery 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 EMF-IncQuery engine in which this matcher will be created.

Throws:

IncQueryException - if an error occurs during pattern matcher creation

Method Detail

on

public static ElementOwnerMatcher on(IncQueryEngine engine)
                              throws IncQueryException

Initializes the pattern matcher within an existing EMF-IncQuery 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 EMF-IncQuery engine in which this matcher will be created.

Throws:

IncQueryException - if an error occurs during pattern matcher creation
