Constructor Detail

OWLOntologyChange

public OWLOntologyChange(OWLOntology ont)

Parameters:

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

Method Detail

getAddedOrRemovedAxiom

public Optional<OWLAxiom> getAddedOrRemovedAxiom()

Returns:

for axiom changes, the axiom added or removed; empty optional otherwise. Same as getAxiom(), but it never throws an exception or returns null.

getAddedAxiom

public Optional<OWLAxiom> getAddedAxiom()

Returns:

for add axiom changes, the axiom added; empty optional otherwise

getRemovedAxiom

public Optional<OWLAxiom> getRemovedAxiom()

Returns:

for remove axiom changes, the axiom removed; empty optional otherwise

isAxiomChange

public boolean isAxiomChange(AxiomType<?> type)

Parameters:

type - axiom type to check

Returns:

true if this is an axiom change and the axiom type is the specified type

isAxiomChange

public boolean isAxiomChange()

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

Returns:

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

isAddAxiom

public boolean isAddAxiom()

Determines if the change will add an axiom to an ontology.

Returns:

true if the change is an AddAxiom change and it will add an axiom to an ontology, false otherwise.

isRemoveAxiom

public boolean isRemoveAxiom()

Determines if the change will remove an axiom from an ontology.

Returns:

true if the change is a RemoveAxiom change and it will remove an axiom from an ontology, false otherwise.

getAxiom

public OWLAxiom getAxiom()

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

Returns:

The Axiom if this change is an axiom change

Throws:

IllegalStateException - if the change has no axiom; UnsupportedOperationException If the change is not an axiom change (check with the isAxiomChange method first).

isImportChange

public boolean isImportChange()

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

Returns:

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

getOntology

public OWLOntology getOntology()

Gets the ontology that the change is/was applied to.

Returns:

The ontology that the change is applicable to

getChangeData

public abstract OWLOntologyChangeData getChangeData()

Gets the data (independent of the ontology) associated with this specific change.

Returns:

The OWLOntologyChangeData associated with this OWLOntologyChange.

getChangeRecord

public OWLOntologyChangeRecord getChangeRecord()

Gets a OWLOntologyChangeRecord that is derived from this OWLOntologyChange's OWLOntologyID and it's OWLOntologyChangeData.

Returns:

An OWLOntologyChangeRecord containing an OWLOntologyID equal to the OWLOntologyID of this OWLOntologyChange's OWLOntology. Not null .

accept

public abstract void accept(OWLOntologyChangeVisitor visitor)

Accepts a visitor.

Parameters:

visitor - The visitor

accept

public abstract <O> O accept(OWLOntologyChangeVisitorEx<O> visitor)

Accepts a visitor.

Type Parameters:

O - visitor return type

Parameters:

visitor - The visitor

Returns:

visitor value

reverseChange

public abstract OWLOntologyChange reverseChange()

Returns:

the reverse of this change; can be used to create undo changes.
