Default constructor setting the comparator to string length comparator.

Method Detail

getPrefixComparator

public StringComparator getPrefixComparator()

Specified by:

getPrefixComparator in interface PrefixManager

Returns:

the prefix comparator currently used by the prefix manager

setPrefixComparator

public void setPrefixComparator(StringComparator comparator)

Specified by:

setPrefixComparator in interface PrefixManager

Parameters:

comparator - the comparator to use

clear

public void clear()

Description copied from interface: PrefixManager

Clear the map.

Specified by:

clear in interface PrefixManager

prefixNames

public Stream<String> prefixNames()

Description copied from interface: PrefixManager

Gets the prefix names that have a mapping in this prefix manager.

Specified by:

prefixNames in interface PrefixManager

Returns:

The prefix names as a set of strings.

getPrefixIRI

@Nullable
public String getPrefixIRI(IRI iri)

Description copied from interface: PrefixManager

Gets the prefix IRI given a IRI (URI).

Specified by:

getPrefixIRI in interface PrefixManager

Parameters:

iri - The IRI whose prefix it to be retrieved

Returns:

The prefix IRI for this IRI, or null if a prefix IRI cannot be generated.

getPrefixIRIIgnoreQName

public String getPrefixIRIIgnoreQName(IRI iri)

Description copied from interface: PrefixManager

Gets the prefix IRI given a IRI (URI). Does not restrict the response to be a QName

Specified by:

getPrefixIRIIgnoreQName in interface PrefixManager

Parameters:

iri - The IRI whose prefix it to be retrieved

Returns:

The prefix IRI for this IRI, or null if a prefix IRI cannot be generated.

getDefaultPrefix

@Nullable
public String getDefaultPrefix()

Description copied from interface: PrefixManager

Gets the default prefix. The default prefix is denoted by the prefix name ":"

Specified by:

getDefaultPrefix in interface PrefixManager

Returns:

The default prefix, or null if there is no default prefix.

setDefaultPrefix

public void setDefaultPrefix(@Nullable
                             String defaultPrefix)

Description copied from interface: PrefixManager

Sets the default namespace. This will also bind the prefix name ":" to this prefix

Specified by:

setDefaultPrefix in interface PrefixManager

Parameters:

defaultPrefix - The namespace to be used as the default namespace. Note that the value may be null in order to clear the default namespace.

containsPrefixMapping

public boolean containsPrefixMapping(String prefixName)

Description copied from interface: PrefixManager

Determines if this manager knows about a given prefix name and it contains a (non-null) mapping for the prefix.

Specified by:

containsPrefixMapping in interface PrefixManager

Parameters:

prefixName - The prefix name to be tested for.

Returns:

true if the manager knows about this prefix and there is a non-null mapping for this prefix.

copyPrefixesFrom

public void copyPrefixesFrom(PrefixManager from)

Description copied from interface: PrefixManager

Copies the prefix from another prefix manager into this one.

Specified by:

copyPrefixesFrom in interface PrefixManager

Parameters:

from - The manager that the prefixes should be copied from

copyPrefixesFrom

public void copyPrefixesFrom(Map<String,String> from)

Description copied from interface: PrefixManager

Copies the prefix from another prefix manager into this one.

Specified by:

copyPrefixesFrom in interface PrefixManager

Parameters:

from - The map containing the prefixes

getIRI

public IRI getIRI(String prefixIRI)

Description copied from interface: PrefixManager

Gets the URI for a given prefix IRI. The prefix IRI must have a prefix name that is registered with this manager, or a runtime exception will be thrown.

Specified by:

getIRI in interface PrefixManager

Parameters:

prefixIRI - The Prefix IRI

Returns:

The full IRI.

getPrefixName2PrefixMap

public Map<String,String> getPrefixName2PrefixMap()

Description copied from interface: PrefixManager

Gets a map that maps prefix names to prefixes.

Specified by:

getPrefixName2PrefixMap in interface PrefixManager

Returns:

The map of prefix names to prefixes. Note that modifying the contents of this map will not change the prefix name - prefix mappings

getPrefix

@Nullable
public String getPrefix(String prefixName)

Description copied from interface: PrefixManager

Gets the prefix that is bound to a particular prefix name. Note that specifying ":" corresponds to requesting the default prefix and will return the same result as a call to the getDefaultPrefix() method.

Specified by:

getPrefix in interface PrefixManager

Parameters:

prefixName - The prefix name. A string that represents a prefix name of the prefix to be retrieved. Note that specifying ":" is the same as asking for the default prefix (see the getDefaultPrefix() method).

Returns:

The prefix, or null if there is no prefix name bound to this prefix, or the prefix name doesn't exist.

setPrefix

public void setPrefix(String inputPrefixName,
                      String prefix)

Description copied from interface: PrefixManager

Adds a prefix name to prefix mapping.

Specified by:

setPrefix in interface PrefixManager

Parameters:

inputPrefixName - name The prefix name (must end with a colon)

prefix - The prefix.

unregisterNamespace

public void unregisterNamespace(String namespace)

Description copied from interface: PrefixManager

Removes a previously registered prefix namespace mapping.

Specified by:

unregisterNamespace in interface PrefixManager

Parameters:

namespace - The namespace to be removed.

getShortForm

public String getShortForm(IRI iri)

Specified by:

getShortForm in interface IRIShortFormProvider

Parameters:

iri - the IRI to shorten

Returns:

the short form

getShortForm

public String getShortForm(OWLEntity entity)

Description copied from interface: ShortFormProvider

Gets the short form for the specified entity.

Specified by:

getShortForm in interface ShortFormProvider

Parameters:

entity - The entity.

Returns:

A string which represents a short rendering of the specified entity. The returned value will not be null but might be an empty string.
