Package org.eclipse.rdf4j.repository.sparql.federation

Class SPARQLServiceResolver

java.lang.Object

org.eclipse.rdf4j.query.algebra.evaluation.federation.AbstractFederatedServiceResolver

org.eclipse.rdf4j.repository.sparql.federation.SPARQLServiceResolver

All Implemented Interfaces:

HttpClientDependent, SessionManagerDependent, org.eclipse.rdf4j.query.algebra.evaluation.federation.FederatedServiceResolver

public class SPARQLServiceResolver
extends org.eclipse.rdf4j.query.algebra.evaluation.federation.AbstractFederatedServiceResolver
implements HttpClientDependent, SessionManagerDependent

The SPARQLServiceResolver is used to manage a set of FederatedService instances, which are used to evaluate SERVICE expressions for particular service Urls.

Lookup can be done via the serviceUrl using the method AbstractFederatedServiceResolver.getService(String). If there is no service for the specified url, a SPARQLFederatedService is created and registered for future use.
