public class GenericQuerySpecification extends GenericQuerySpecification<org.eclipse.viatra.query.patternlanguage.emf.specification.GenericPatternMatcher>
This is a generic query specification for VIATRA Query pattern matchers, for "interpretative" query execution. Instantiate the specification with any registered pattern (or through aSpecificationBuilder
instance), and then use the specification to obtain an actual pattern matcher operating on a given model.When available, consider using the pattern-specific generated matcher API instead.
The created matcher will be of type org.eclipse.viatra.query.runtime.api.GenericPatternMatcher. Matches of the pattern will be represented as GenericPatternMatch.

getInternalQueryRepresentation
public GenericEMFPatternPQuery getInternalQueryRepresentation()
Description copied from interface:IQuerySpecification
Returns the definition of the query in a format intended for consumption by the query evaluator.- Specified by:
getInternalQueryRepresentation
in interfaceIQuerySpecification<org.eclipse.viatra.query.patternlanguage.emf.specification.GenericPatternMatcher>
- Overrides:
getInternalQueryRepresentation
in classBaseQuerySpecification<org.eclipse.viatra.query.patternlanguage.emf.specification.GenericPatternMatcher>
- Returns:
- the internal representation of the query.
-
instantiate
public org.eclipse.viatra.query.patternlanguage.emf.specification.GenericPatternMatcher instantiate(ViatraQueryEngine engine)
- Specified by:

in classBaseQuerySpecification<org.eclipse.viatra.query.patternlanguage.emf.specification.GenericPatternMatcher>
-
getPreferredScopeClass
public java.lang.Class<? extends QueryScope> getPreferredScopeClass()
Description copied from interface:IQuerySpecification
The query is formulated over this kind of modeling platform. E.g. for queries over EMF models, theEMFScope
class is returned.
