Class GenericQuerySpecification

java.lang.Object

org.eclipse.incquery.runtime.api.impl.BaseQuerySpecification<Matcher>

org.eclipse.incquery.runtime.api.GenericQuerySpecification<GenericPatternMatcher>

org.eclipse.incquery.patternlanguage.emf.specification.GenericQuerySpecification

All Implemented Interfaces:

IQuerySpecification<GenericPatternMatcher>, PQueryHeader

public class GenericQuerySpecification
extends GenericQuerySpecification<GenericPatternMatcher>

This is a generic query specification for EMF-IncQuery pattern matchers, for "interpretative" query execution. Instantiate the specification with any registered pattern (or through a SpecificationBuilder 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.incquery.runtime.api.GenericPatternMatcher. Matches of the pattern will be represented as GenericPatternMatch.

Method Detail

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 interface IQuerySpecification<GenericPatternMatcher>

Overrides:

getInternalQueryRepresentation in class BaseQuerySpecification<GenericPatternMatcher>

Returns:

the internal representation of the query.

instantiate

public GenericPatternMatcher instantiate(IncQueryEngine engine)
                                  throws IncQueryException

Throws:

IncQueryException

getPreferredScopeClass

public java.lang.Class<? extends IncQueryScope> getPreferredScopeClass()

Description copied from interface: IQuerySpecification

The query is formulated over this kind of modeling platform. E.g. for queries over EMF models, the EMFScope class is returned.
