Interface Summary

Interface	Description
ImportsExpander	An interface that can be implemented by a Dataset to support the SWP function ui:graphWithImports.
OntologyOptimizableGraph	An abstraction layer that helps the OntologyOptimizations determine whether it needs to invalidate caches or whether the graph can benefit from caching at all.
OptimizedMultiUnion	A Graph interface providing additional optimization features.
ParameterProvider	A platform independent wrapper of HttpServletRequest, factoring out the getParameter method.

Class Summary

Class	Description
AbstractGraphListener	An abstract GraphListeners that forwards each call into GraphListener.notifyAddTriple(org.apache.jena.graph.Graph, org.apache.jena.graph.Triple) and GraphListener.notifyDeleteTriple(org.apache.jena.graph.Graph, org.apache.jena.graph.Triple) to reduce the implementation burden of subclasses.
ClassMetadata	Represents some ontology-related data about a given class, so that it can be accessed more efficiently than through the RDF triples.
ClassPropertyMetadata	Metadata about a property at a given class.
CommandWrapper	Wraps a (pre-compiled) Jena Query or UpdateRequest with its source SPIN object and a human-readable string representation.
ConcurrentHashSet<E>	A set that uses ConcurrentHashMap as its implementation.
DatasetWrappingDatasetGraph	An implementation of DatasetGraph that delegates all work to a given Dataset implementation.
ExceptionUtil	A collection of utilities on Exception handling.
GraphBulkUpdate	Utility methods that allow switching between the deprecated BulkUpdateHandler and the supposed replacement in GraphUtil later.
ImplementationByType	Extended polymorphism support for Jena, checking whether the Node has a given rdf:type.
ImportProperties	A singleton controlling which properties shall be used to expand imports.
IOUtil
JenaDatatypes	Some static utilities dealing with datatypes and literals.
JenaNodeUtil	Some utilities operating on Jena Node objects, bypassing the Model/RDFNode abstraction layer.
JenaUtil	Some convenience methods to operate on Jena Models.
JenaUtilHelper	This is an extension point for the SPIN library allowing modification of some low level utilities that are exposed through JenaUtil.
LocalRangeAtClassNativeFunction	A native implementation of swa:localRangeAtClass, to optimize performance.
ModulesUtil	Utilities on SPIN modules.
NestedQueries	Utility to checks whether a given Query contains "nested" elements such as UNIONs or sub-SELECTs.
OntologyOptimizations	A singleton managing Ontology-based optimizations, to be used (for example) with OptimizedMultiUnions.
OntologyOptimizations.MyCache
PropertyPathsGetter	A utility that can be used to find all SimplePropertyPaths encoded in a SPIN element where either subject or object is ?this.
QueryWrapper	A CommandWrapper that wraps a SPARQL query (in contrast to UpdateWrapper for UPDATE requests).
RelevantProperties	Control logic that determines "relevant" properties for given classes or instances.
SimpleImplementation	An extension of the Jena polymorphism mechanism.
SimpleImplementation2	An extension of the Jena polymorphism mechanism.
SimpleParameterProvider	A simple implementation of the ParameterProvider interface, based on a HashMap.
SPINExpressions	Static utilities on SPIN Expressions.
SPINQueryFinder	Can be used to search for all queries associated with a class, e.g.
SPINUtil	Some static util methods for SPIN that don't fit anywhere else.
SPLUtil	Utilities related to the spl namespace.
SPTextUtil	A utility to convert RDF graphs between the sp:text syntax and SPIN RDF triples.
SystemTriples	Provides access to the RDF/RDFS/OWL system triples.
UpdateUtil	Utility on SPARQL Update operations.
UpdateWrapper	A CommandWrapper that wraps SPARQL UPDATE requests (in contrast to QueryWrapper for SPARQL queries).
XMLOutput	Simple utilities for XML.
