Class OWLRuleReasoner  

java.lang.Object
  com.hp.hpl.jena.reasoner.rulesys.BasicForwardRuleReasoner
      com.hp.hpl.jena.reasoner.rulesys.impl.oldCode.OWLRuleReasoner

All Implemented Interfaces:

com.hp.hpl.jena.reasoner.Reasoner

---

Deprecated. Obsoleted post jena2.0, replaced by com.hp.hpl.jena.reasoner.rulesys.OWLFBRuleReasoner. An pure forward chaining implementation of the experimental OWL closure rules based upon the basic forward rule interpreter. This is not a serious or usable OWL implementation, it is a tool for developing the rules.

TODO: Replace intersection-translation step by rule based alternative (or failing that figure out what should be done at the bindSchema stage).

OWLRuleReasoner

private OWLRuleReasoner(java.util.List rules,
                        com.hp.hpl.jena.reasoner.InfGraph schemaGraph)

Deprecated. 

Internal constructor, used to generated a partial binding of a schema to a rule reasoner instance.

Method Detail

loadRules

public static java.util.List loadRules()

Deprecated. 

Return the RDFS rule set, loading it in if necessary

---

bindSchema

public com.hp.hpl.jena.reasoner.Reasoner bindSchema(com.hp.hpl.jena.graph.Graph tbox)
                                             throws com.hp.hpl.jena.reasoner.ReasonerException

Deprecated. 

Precompute the implications of a schema graph. The practical benefit of this has not yet been fully checked out.

---

bind

public com.hp.hpl.jena.reasoner.InfGraph bind(com.hp.hpl.jena.graph.Graph data)
                                       throws com.hp.hpl.jena.reasoner.ReasonerException

Deprecated. 

Attach the reasoner to a set of RDF data to process. The reasoner may already have been bound to specific rules or ontology axioms (encoded in RDF) through earlier bindRuleset calls.

---

printStats

public static void printStats()

Deprecated. 

Print (to the default logging channel at Info level) a summary of the total number of rules fired and the time taken by the reasoner instances created thus far.

---

translateIntersectionOf

private void translateIntersectionOf(com.hp.hpl.jena.graph.Triple decl,
                                     java.util.List rules,

Deprecated. 

Translation code to compile intersectionOf declarations. In the future this will be replaced by a rule-baesd translator which will cope with dynamic expressions.

---

translateIntersectionList

private void translateIntersectionList(com.hp.hpl.jena.graph.Node node,
                                       com.hp.hpl.jena.graph.Graph data,
                                       java.util.List elements)
