Package com.bigdata.rdf.sparql.ast.service

This package provides support for SPARQL 1.1 Federated Query, including the special case of "service" end points which live within the same JVM and use direct method calls rather than SPARQL Query and remote (HTTP) end points for which we will generate an appropriate SPARQL query.

Interface Summary

Interface	Description
BigdataServiceCall	Service invocation interface for an in-process service which knows how to process IVs.
CustomServiceFactory	Interface for custom services.
ExternalServiceCall	Service invocation interface for an external (non-bigdata, but same JVM) service.
INativeServiceOptions	Additional options for native services.
IRemoteSparqlQueryBuilder	Interface for objects which can construct a valid SPARQL query for execution against a remote SPARQL end point.
IServiceOptions	Options and metadata for service end points.
MockIVReturningServiceCall	Service invocation interface for an external (non-bigdata) service.
RemoteServiceCall	Service invocation interface for an REMOTE SPARQL service.
ServiceCall<E>	Service invocation interface.
ServiceCallCreateParams	Interface for the parameters used by a ServiceFactory to create a ServiceCall instance.
ServiceFactory	Factory for creating objects which can talk to SPARQL service end points.

Class Summary

Class	Description
BigdataNativeServiceOptions	Service options base class for bigdata aware services.
NullServiceFactory	This service factory will always produce empty result.
OpenrdfNativeServiceOptions	Service options base class for with JVM services which handle openrdf BindingSets rather than bigdata IBindingSets.
RemoteServiceCallImpl	This class handles vectored remote service invocation by generating an appropriate SPARQL query (with BINDINGS) and an appropriate HTTP request.
RemoteServiceFactoryImpl	A factory for service calls against remote SPARQL end points.
RemoteServiceOptions	Configurable options for a remote service end point.
RemoteSparql10QueryBuilder	Utility class constructs a valid SPARQL query for a remote SPARQL 1.0 end point (no BINDINGS clause and does not support SELECT expressions or BIND()).
RemoteSparql11DraftQueryBuilder	Utility class constructs a valid SPARQL query for a remote SPARQL 1.1 using the BINDINGS clause to vector solutions into that remote end point.
RemoteSparql11QueryBuilder	Utility class constructs a valid SPARQL query for a remote SPARQL 1.1 using the VALUES clause to vector solutions into that remote end point.
RemoteSparqlBuilderFactory	Factory encapsulates the logic required to decide on the manner in which solutions will be vectored into the remote service end point and in which the solutions flowing back from that service will be interpreted.
ServiceCallUtility	Helper class for ServiceCall invocations.
ServiceNode	An extension point for external service calls which produce solution multisets (a SPARQL SERVICE).
ServiceOptionsBase
ServiceRegistry	Registry for service calls.
