org.eclipse.viatra.integration.uml.derivedfeatures.NamedElementNamespaceMatcher

All Implemented Interfaces:

ViatraQueryMatcher<NamedElementNamespaceMatch>

public class NamedElementNamespaceMatcher
extends BaseMatcher<NamedElementNamespaceMatch>

Generated pattern matcher API of the org.eclipse.viatra.integration.uml.derivedfeatures.namedElementNamespace 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 NamedElementNamespaceMatch.

Original source:

 NamedElementOperations.getNamespace
 
  @Surrogate(feature = "namespace")
  @QueryExplorer(checked = false)
 pattern namedElementNamespace(source: NamedElement, target: Namespace) {
     // opposite of Namespace.ownedMember
     find namespaceOwnedMember(target, source);
 }

Method Detail

on

public static NamedElementNamespaceMatcher 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

public static NamedElementNamespaceMatcher 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.

Returns the set of all matches of the pattern that conform to the given fixed values of some parameters.

Parameters:

pSource - the fixed value of pattern parameter source, or null if not bound.

Returns an arbitrarily chosen match of the pattern that conforms to the given fixed values of some parameters. Neither determinism nor randomness of selection is guaranteed.

Parameters:

pSource - the fixed value of pattern parameter source, or null if not bound.

pTarget - the fixed value of pattern parameter target, or null if not bound.

Returns:

a match represented as a NamedElementNamespaceMatch object, or null if no match is found.

Parameters:

pSource - the fixed value of pattern parameter source, or null if not bound.
