Constructor Detail

DefaultURI2NameConverter

public DefaultURI2NameConverter(OWLModel owlModel,
                                ProtegeOWLParserLogger logger,
                                boolean incremental)

Method Detail

addPrefix

public String addPrefix(String uri,
                        String prefix)

Description copied from interface: URI2NameConverter

Adds a new prefix-namespace pair to this converter. If the namespace is already used under a different prefix then the already existing one will be used and returned. If the prefix is already used for a different namespace, then the prefix will not be used.

Specified by:

addPrefix in interface URI2NameConverter

Parameters:

uri - the URI/namespace

prefix - the new prefix

Returns:

the prefix that will be used for the namespace

addPrefixHelper

private void addPrefixHelper(String uri,
                             String prefix)

createAnonymousRDFResourceName

public String createAnonymousRDFResourceName()

Specified by:

createAnonymousRDFResourceName in interface URI2NameConverter

createNewPrefixHelper

private String createNewPrefixHelper(String namespace)

createNewPrefix

public String createNewPrefix(String uri)

Description copied from interface: URI2NameConverter

Creates a dummy prefix and adds it to the OWLModel

Specified by:

createNewPrefix in interface URI2NameConverter

Parameters:

uri - the URI of the resource to create a new prefix for

getNamespace

private String getNamespace(String prefix)

getPrefix

private String getPrefix(String uri)

getRDFExternalResourceName

public String getRDFExternalResourceName()

Specified by:

getRDFExternalResourceName in interface URI2NameConverter

getRDFResourceName

public String getRDFResourceName(String uri)

Description copied from interface: URI2NameConverter

Gets the Protege resource name for a given URI.

Specified by:

getRDFResourceName in interface URI2NameConverter

Parameters:

uri - the URI to get the name of

Returns:

the Protege name (not null)

getResourceNamespace

public String getResourceNamespace(String uri)

Description copied from interface: URI2NameConverter

Gets the namespace part of a resource URI. This typically wraps the Jena namespace split algorithm.

Specified by:

getResourceNamespace in interface URI2NameConverter

Parameters:

uri - the URI to get the namespace of

Returns:

the namespace (usually including the '#')

getTemporaryRDFResourceName

public String getTemporaryRDFResourceName(String uri)

Specified by:

getTemporaryRDFResourceName in interface URI2NameConverter

getTemporaryRDFResourceName

public String getTemporaryRDFResourceName(com.hp.hpl.jena.rdf.arp.AResource node)

Specified by:

getTemporaryRDFResourceName in interface URI2NameConverter

getURIFromTemporaryName

public String getURIFromTemporaryName(String temporaryName)

Description copied from interface: URI2NameConverter

The inverse of getTemporaryRDFResourceName().

Specified by:

getURIFromTemporaryName in interface URI2NameConverter

Parameters:

temporaryName - the temporary name

Returns:

the URI encoded by the temp name

initPrefixesFromOWLModel

private void initPrefixesFromOWLModel()

isAnonymousRDFResourceName

public boolean isAnonymousRDFResourceName(String name)

Description copied from interface: URI2NameConverter

Checks whether a given name describes an anonymous resource.

Specified by:

isAnonymousRDFResourceName in interface URI2NameConverter

Parameters:

name - the name of the resource to test

Returns:

true if name is an anonymous name

isPreferredPrefix

protected boolean isPreferredPrefix(String prefix,
                                    String uri)

isTemporaryRDFResourceName

public boolean isTemporaryRDFResourceName(String name)

Description copied from interface: URI2NameConverter

Checks if this is a name that was created as a temporary name before. Temporary names should follow a naming convention which keeps them clearly separate from real names.

Specified by:

isTemporaryRDFResourceName in interface URI2NameConverter

Parameters:

name - the name to test

Returns:

true if name is a temporary test

updateInternalState

public void updateInternalState()

Description copied from interface: URI2NameConverter

Called after the triples have been copied and new namespace prefixes assigned. This method must update the internal state of the converter to reflect possible changes during loading (e.g. add new prefixes).

Specified by:

updateInternalState in interface URI2NameConverter
