                            boolean forceId,
                            boolean isAxiom)

Create an RDFResource that is anonymous

Parameters:

resource - The IRI of the resource

isIndividual - true if this is an individual

forceId - true if the id should be outputted

isAxiom - true if axiom

RDFResourceBlankNode

public RDFResourceBlankNode(Integer anonId,
                            boolean isIndividual,
                            boolean forceId,
                            boolean isAxiom)

Create an RDFResource that is anonymous

Parameters:

anonId - the number at the end of the anon IRI

isIndividual - true if this is an individual

forceId - true if the id should be outputted

isAxiom - true if axiom

RDFResourceBlankNode

public RDFResourceBlankNode(boolean isIndividual,
                            boolean forceId,
                            boolean isAxiom)

Create an RDFResource that is anonymous

Parameters:

isIndividual - true if this is an individual

forceId - true if the id should be outputted

isAxiom - true if axiom

Method Detail

isIndividual

public boolean isIndividual()

Overrides:

isIndividual in class RDFNode

Returns:

true if this is an anonymous individual

isAxiom

public boolean isAxiom()

Description copied from class: RDFNode

Determines if this node is an axiom.

Overrides:

isAxiom in class RDFNode

Returns:

true if this node is a literal, otherwise false.

shouldOutputId

public boolean shouldOutputId()

Overrides:

shouldOutputId in class RDFNode

Returns:

true if blank node id is mandatory for this resource

isLiteral

public boolean isLiteral()

Description copied from class: RDFNode

Determines if this node is a literal node.

Specified by:

isLiteral in class RDFNode

Returns:

true if this node is a literal, otherwise false.

isAnonymous

public boolean isAnonymous()

Description copied from class: RDFNode

Determines if this node is a resource and is anonymous.

Specified by:

isAnonymous in class RDFNode

Returns:

true if this is a resource node (i.e. isLiteral returns false) and the node is anonymous, or false if this is a resource node and is not anonymous.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

toString

@Nonnull
public String toString()

Overrides:

toString in class Object

getIRI

public IRI getIRI()

Description copied from interface: HasIRI

Gets the IRI of this object

Returns:

The IRI of this object

getResource

public IRI getResource()

Specified by:

getResource in class RDFResource

Returns:

the resource IRI

getNodeIDValue

public String getNodeIDValue()

Description copied from class: RDFResource

For blank nodes, return a valid value for thr rdf/xml nodeId attribute. For non blank nodes, an exception should be thrown. The method must only be called on blank nodes.

Specified by:

getNodeIDValue in class RDFResource

Returns:

a valid value for thr rdf/xml nodeId attribute
