Constructor Detail

OWLAxiomChange

public OWLAxiomChange(@Nonnull
                      OWLOntology ont,
                      @Nonnull
                      OWLAxiom axiom)

Parameters:

ont - the ontology to which the change is to be applied

axiom - the axiom to be changed

Method Detail

getSignature

public Set<OWLEntity> getSignature()

Description copied from class: OWLOntologyChange

Gets the signature of this ontology change. That is, the set of entities appearing in objects in this change.

Specified by:

getSignature in interface HasSignature

Specified by:

getSignature in class OWLOntologyChange

Returns:

A set of entities that correspond to the signature of this object. The set is a copy, changes are not reflected back.

isAxiomChange

public boolean isAxiomChange()

Description copied from class: OWLOntologyChange

Determines if the change will cause the addition or removal of an axiom from an ontology.

Specified by:

isAxiomChange in class OWLOntologyChange

Returns:

true if the change is an OWLAddAxiomChange or OWLRemoveAxiomChange otherwise false.

isImportChange

public boolean isImportChange()

Description copied from class: OWLOntologyChange

Determines if this change is an import change and hence causes a change to the imports closure of an ontology.

Specified by:

isImportChange in class OWLOntologyChange

Returns:

true if this change is an import change, otherwise false.

getAxiom

@Nonnull
public OWLAxiom getAxiom()

Description copied from class: OWLOntologyChange

If the change is an axiom change (i.e. AddAxiom or RemoveAxiom) this method obtains the axiom.

Specified by:

getAxiom in class OWLOntologyChange

Returns:

The Axiom if this change is an axiom change
