public class ARTBNodeEmptyImpl
extends ARTResourceEmptyImpl
implements ARTBNode

OWL ART API are an abstraction layer over different triple store technologies
For this reason, interface implementations for RDF nodes in OWL ART API are usually provided by the wrappers for different triple store technologies. However, there could be times where basic implementations of RDF nodes are required by processes which need to be independent from any triplestore technology, for instance, when initializing the various RDF vocabularies, such as RDF, RDFS, OWL , SKOS, SKOSXL, which is statically done outside of any model loaded through any specific implementation

asBNode in interface ARTNode

isBlank

public boolean isBlank()

Description copied from interface: ARTNode

Answer true iff this STNode is an anonynous resource.

Specified by:

isBlank in interface ARTNode

isURIResource

public boolean isURIResource()

Description copied from interface: ARTNode

equals

public boolean equals(Object o)

Description copied from interface: ARTBNode

Compares a URI object to another object.

Specified by:

equals in interface ARTBNode

Specified by:

equals in interface ARTNode

Overrides:

equals in class Object

Parameters:

o - The object to compare this URI to.

Returns:

true if the other object is an instance of URI and their String-representations are equal, false otherwise.

toString

public String toString()

Description copied from interface: ARTNode

a non-ambiguous and compact way for representing the node content, according to IRI-refs. Depends on the nature of the node

Specified by:

toString in interface ARTNode

Overrides:

Returns:

for URIs/IRIs: plain URI/IRI, for BNodes: the _:id notation, for literals: "literalvalue"[^^<datatype>|@languagetag]

getNominalValue

public String getNominalValue()

Description copied from interface: ARTNode

depends on the nature of the node

Specified by:

getNominalValue in interface ARTNode

Returns:

for URIs/IRIs: plain URI/IRI, for BNodes: the sole id, for literals: the sole label
