org.apache.jena.reasoner.rulesys.OWLFBRuleReasonerFactory

All Implemented Interfaces:

ReasonerFactory

public class OWLFBRuleReasonerFactory
extends Object
implements ReasonerFactory

Factory class for creating blank instances of the OWL Reasoner.

The reasoner can be configured using three properties (set as properties of the base reasonder URI in a configuration model). These are:

• derivationLogging - if set to true this causes all derivations to be recorded in an internal data structure for replay through the getDerivation method.
• traceOn - if set to true this causes all rule firings and deduced triples to be written out to the Logger at INFO level.

Method Details

theInstance

public static ReasonerFactory theInstance()

Return the single global instance of this factory

create

public Reasoner create(Resource configuration)

Constructor method that builds an instance of the associated Reasoner

Specified by:

create in interface ReasonerFactory

Parameters:

configuration - a set of arbitrary configuration information to be passed the reasoner encoded within an RDF graph

getCapabilities

public Model getCapabilities()

Return a description of the capabilities of this reasoner encoded in RDF. This method is normally called by the ReasonerRegistry which caches the resulting information so dynamically creating here is not really an overhead.

Specified by:

getCapabilities in interface ReasonerFactory

getURI

public String getURI()

Return the URI labelling this type of reasoner

Specified by:

getURI in interface ReasonerFactory
