Method Summary

java.util.Set<OWLAxiom>	extract(java.util.Set<OWLEntity> signature) Returns a set of axioms that is a segment of the ontology associated with this segmenter.
OWLOntology	extractAsOntology(java.util.Set<OWLEntity> signature, java.net.URI uri) Returns an ontology that is a segment of the ontology associated with this segmenter.

Method Detail

extract

java.util.Set<OWLAxiom> extract(java.util.Set<OWLEntity> signature)

Returns a set of axioms that is a segment of the ontology associated with this segmenter.

Parameters:

signature - the seed signature (set of entities) for the segment

Returns:

the segment as a set of axioms

extractAsOntology

OWLOntology extractAsOntology(java.util.Set<OWLEntity> signature,
                              java.net.URI uri)
                              throws OWLOntologyCreationException,
                                     OWLOntologyChangeException

Returns an ontology that is a segment of the ontology associated with this segmenter.

Parameters:

signature - the seed signature (set of entities) for the module

uri - the URI for the module

Returns:

the module, having the specified URI

Throws:

OWLOntologyChangeException - if adding axioms to the module fails

OWLOntologyCreationException - if the module cannot be created
