public class AutoIRIMapper
extends org.xml.sax.helpers.DefaultHandler
implements OWLOntologyIRIMapper, Serializable

Constructor Detail

AutoIRIMapper

public AutoIRIMapper(File rootDirectory,
                     boolean recursive)

Creates an auto-mapper which examines ontologies that reside in the specified root folder (and possibly sub-folders).

Parameters:

rootDirectory - The root directory which should be searched for ontologies.

recursive - Sub directories will be searched recursively if true.

Method Detail

getParserFactory

protected SAXParserFactory getParserFactory()

getDirectory

protected File getDirectory()

getCurrentFile

protected File getCurrentFile()

getFileExtensions

public Set<String> getFileExtensions()

The mapper only examines files that have specified file extensions. This method returns the file extensions that cause a file to be examined.

Returns:

A Set of file extensions.

setFileExtensions

public void setFileExtensions(Set<String> extensions)

Sets the extensions of files that are to be examined for ontological content. (By default the extensions are, owl, xml and rdf). Only files that have the specified extensions will be examined to see if they contain ontologies.

Parameters:

extensions - the set of extensions

getOntologyIRIs

public Set<IRI> getOntologyIRIs()

Gets the set of ontology IRIs that this mapper has found.

Returns:

A Set of ontology (logical) URIs

update

public void update()

update the map.

getDocumentIRI

public IRI getDocumentIRI(IRI ontologyIRI)

Description copied from interface: OWLOntologyIRIMapper

Given an ontology IRI, this method maps the ontology IRI to a document IRI.

Specified by:

getDocumentIRI in interface OWLOntologyIRIMapper

Parameters:

ontologyIRI - The ontology IRI to be mapped.

Returns:

The document IRI of the ontology, or null if the mapper doesn't have mapping for the specified ontology IRI.

startElement

public void startElement(String uri,
                         String localName,
                         String qName,
                         Attributes attributes)
                  throws SAXException

Specified by:

startElement in interface ContentHandler

Overrides:

startElement in class org.xml.sax.helpers.DefaultHandler

Throws:

SAXException

toString

public String toString()

Overrides:

toString in class Object
