Method Detail

asStringLiteral

public static org.apache.jena.rdf.model.Literal asStringLiteral(String value,

Maps a string to a literal term.

Parameters:

value - the value to map

model - the graph that serves as the context for creating the term

Returns:

an xsd:string typed literal with the string as its lexical form

Throws:

NullPointerException - if the value is null

NullPointerException - if the model is null

asIri

public static org.apache.jena.rdf.model.Resource asIri(String value,
                                                       org.apache.jena.rdf.model.Model model)

Maps an IRI string to an IRI term.

Parameters:

value - the value to map

model - ignored

Returns:

an IRI term with the string as its identifier

Throws:

NullPointerException - if the value is null

NullPointerException - if the model is null

asIri

public static org.apache.jena.rdf.model.Resource asIri(URI value,
                                                       org.apache.jena.rdf.model.Model model)

Maps a URI to an IRI term.

Parameters:

value - the value to map

Returns:

an IRI term with the URI as its identifier

Throws:

NullPointerException - if the value is null

NullPointerException - if the model is null

asTypedLiteral

public static org.apache.jena.rdf.model.Literal asTypedLiteral(Instant value,
                                                               org.apache.jena.rdf.model.Model model)

Maps a point in time to a literal term.

Parameters:

Returns:

an xsd:dateTime typed literal term with the point in time as its lexical value

Throws:

NullPointerException - if the value is null

NullPointerException - if the model is null

asTypedLiteral

public static org.apache.jena.rdf.model.Literal asTypedLiteral(Boolean value,
                                                               org.apache.jena.rdf.model.Model model)

Maps a boolean value to a literal node.

Parameters:

value - the value to map

model - the graph used to create the node

Returns:

an xsd:boolean typed literal node with the boolean value as its lexical value
