RDFResourceBlankNode

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

Create an RDFResource that is anonymous.

Parameters:

resource - The IRI of the resource

isIndividual - true if the node represents an individual

forceId - true if id should be output

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 the node represents an individual

forceId - true if id should be output

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 output

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

setIdRequired

public void setIdRequired(boolean b)

Parameters:

b - change the value of the id required flag

isLiteral

public boolean isLiteral()

Description copied from class: RDFNode

Determines if this node is a literal node.

Overrides:

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.

Overrides:

isAnonymous in class RDFNode

Returns:

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

Specified by:

getNodeIDValue in class RDFResource

Returns:

a valid value for thE RDF/XML nodeId attribute
