Method Detail

clearDependencies

void clearDependencies(org.semanticweb.owlapi.model.OWLOntologyID dependent)

Liberates the selected ontology from all its bindings with other ontologies, excluding ontology collectors. As a consequence, no import statements other than those pointing to ontology collectors, if any, should appear when exporting the ontology.

Parameters:

dependent - the ontology to be cleared of dependencies.

getDependencies

Set<org.semanticweb.owlapi.model.OWLOntologyID> getDependencies(org.semanticweb.owlapi.model.OWLOntologyID dependent)

Returns all the ontologies that the supplied ontology depends on, if any.

Parameters:

dependent - the public key of the depending ontology.

Returns:

the set of dependencies (possibly empty).

getDependents

Set<org.semanticweb.owlapi.model.OWLOntologyID> getDependents(org.semanticweb.owlapi.model.OWLOntologyID dependency)

Returns all the ontologies that depend on the supplied ontology, if any.

Parameters:

dependency - the public key of the ontology that other ontologies could depend on.

Returns:

the set of ontologies it depends on (possibly empty).

getHandles

Set<OntologyCollector> getHandles(org.semanticweb.owlapi.model.OWLOntologyID publicKey)

Not just the IDs because spaces and sessions can share identifiers.

Parameters:

publicKey -

Returns:

getPublicKey

org.semanticweb.owlapi.model.OWLOntologyID getPublicKey(String stringForm)

An utility method that computes the public key of an ontology given a canonical string form. The result also depends on the stored ontologies, hence the inclusion of this non-static method with this class.

Parameters:

stringForm - the string form of the public key.

Returns:

the public key.

getPublicKeys

Set<org.semanticweb.owlapi.model.OWLOntologyID> getPublicKeys()

Returns the public keys of all the stored ontologies it is aware of.

Returns:

the public key set.

getSize

int getSize(org.semanticweb.owlapi.model.OWLOntologyID publicKey)

Returns the size in triples of the ontology with the supplied public key. Depending on the implementation, the size can be cached or computed on-the-fly.

Parameters:

publicKey - the public key of the ontology

Returns:

the size in triples of the ontology.

removeDependency

void removeDependency(org.semanticweb.owlapi.model.OWLOntologyID dependent,
                      org.semanticweb.owlapi.model.OWLOntologyID dependency)

Removes any claim that stored ontology dependent has a dependency on stored ontology dependency. As a consquence, no related import statement should figure in the serialized dependant. Note that this operation can be overridden by a call to setDependency(OWLOntologyID, OWLOntologyID).

Parameters:

dependent - the depending ontology.

dependency - the ontology it depends on.

setDependency

void setDependency(org.semanticweb.owlapi.model.OWLOntologyID dependent,
                   org.semanticweb.owlapi.model.OWLOntologyID dependency)

States that stored ontology dependant has a dependency on stored ontology dependency, e.g. because the former imports the latter. As a consequence, various restrictions could apply, e.g. dependency cannot be deleted as long as it is a dependency.

Parameters:

dependent - the depending ontology.

dependency - the ontology it depends on.
