Constructor Detail

OWLReasonerBase

protected OWLReasonerBase(OWLOntology rootOntology,
               OWLReasonerConfiguration configuration,
               BufferingMode bufferingMode)

Method Detail

getReasonerConfiguration

public OWLReasonerConfiguration getReasonerConfiguration()

Returns:

the configuration

getBufferingMode

public BufferingMode getBufferingMode()

Specified by:

getBufferingMode in interface OWLReasoner

getTimeOut

public long getTimeOut()

Specified by:

getTimeOut in interface OWLReasoner

getRootOntology

public OWLOntology getRootOntology()

Specified by:

getRootOntology in interface OWLReasoner

handleRawOntologyChanges

protected void handleRawOntologyChanges(List<? extends OWLOntologyChange> changes)

Handles raw ontology changes. If the reasoner is a buffering reasoner then the changes will be stored in a buffer. If the reasoner is a non-buffering reasoner then the changes will be automatically flushed through to the change filter and passed on to the reasoner.

Parameters:

changes - The list of raw changes.

getPendingChanges

public List<OWLOntologyChange> getPendingChanges()

Specified by:

getPendingChanges in interface OWLReasoner

getPendingAxiomAdditions

public Set<OWLAxiom> getPendingAxiomAdditions()

Specified by:

getPendingAxiomAdditions in interface OWLReasoner

getPendingAxiomRemovals

public Set<OWLAxiom> getPendingAxiomRemovals()

Specified by:

getPendingAxiomRemovals in interface OWLReasoner

flush

public void flush()

Specified by:

flush in interface OWLReasoner

getReasonerAxioms

public Collection<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<OWLAxiom> addAxioms,
                 Set<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 OWLReasoner

getFreshEntityPolicy

public FreshEntityPolicy getFreshEntityPolicy()

Specified by:

getFreshEntityPolicy in interface OWLReasoner

getIndividualNodeSetPolicy

public IndividualNodeSetPolicy getIndividualNodeSetPolicy()

Specified by:

getIndividualNodeSetPolicy in interface OWLReasoner

getOWLDataFactory

public OWLDataFactory getOWLDataFactory()

Returns:

the data factory
