OWLReasonerBase

protected OWLReasonerBase(org.semanticweb.owlapi.model.OWLOntology rootOntology,
                          org.semanticweb.owlapi.reasoner.OWLReasonerConfiguration configuration,
                          org.semanticweb.owlapi.reasoner.BufferingMode bufferingMode)

Method Detail

getReasonerConfiguration

public org.semanticweb.owlapi.reasoner.OWLReasonerConfiguration getReasonerConfiguration()

Returns:

the configuration

getBufferingMode

public org.semanticweb.owlapi.reasoner.BufferingMode getBufferingMode()

Specified by:

getBufferingMode in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getTimeOut

public long getTimeOut()

Specified by:

getTimeOut in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getRootOntology

public org.semanticweb.owlapi.model.OWLOntology getRootOntology()

Specified by:

getRootOntology in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getPendingChanges

public List<org.semanticweb.owlapi.model.OWLOntologyChange> getPendingChanges()

Specified by:

getPendingChanges in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getPendingAxiomAdditions

public Set<org.semanticweb.owlapi.model.OWLAxiom> getPendingAxiomAdditions()

Specified by:

getPendingAxiomAdditions in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getPendingAxiomRemovals

public Set<org.semanticweb.owlapi.model.OWLAxiom> getPendingAxiomRemovals()

Specified by:

getPendingAxiomRemovals in interface org.semanticweb.owlapi.reasoner.OWLReasoner

flush

public void flush()

Flushes the pending changes from the pending change list. The changes will be analysed to determine which axioms have actually been added and removed from the imports closure of the root ontology and then the reasoner will be asked to handle these changes via the handleChanges(java.util.Set, java.util.Set) method.

Specified by:

flush in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getReasonerAxioms

public Collection<org.semanticweb.owlapi.model.OWLAxiom> getReasonerAxioms()

Gets the axioms that should be currently being reasoned over.

Returns:

A collections of axioms (not containing duplicates) that the reasoner should be taking into consideration when reasoning. This set of axioms many not correspond to the current state of the imports closure of the reasoner root ontology if the reasoner is buffered.

handleChanges

protected abstract void handleChanges(Set<org.semanticweb.owlapi.model.OWLAxiom> addAxioms,
                                      Set<org.semanticweb.owlapi.model.OWLAxiom> removeAxioms)

Asks the reasoner implementation to handle axiom additions and removals from the imports closure of the root ontology. The changes will not include annotation axiom additions and removals.

Parameters:

addAxioms - The axioms to be added to the reasoner.

removeAxioms - The axioms to be removed from the reasoner

dispose

public void dispose()

Specified by:

dispose in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getFreshEntityPolicy

public org.semanticweb.owlapi.reasoner.FreshEntityPolicy getFreshEntityPolicy()

Specified by:

getFreshEntityPolicy in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getIndividualNodeSetPolicy

public org.semanticweb.owlapi.reasoner.IndividualNodeSetPolicy getIndividualNodeSetPolicy()

Specified by:

getIndividualNodeSetPolicy in interface org.semanticweb.owlapi.reasoner.OWLReasoner

getOWLDataFactory

public org.semanticweb.owlapi.model.OWLDataFactory getOWLDataFactory()

Returns:

the data factory
