Class NV

java.lang.Object

org.apache.jena.sparql.function.js.NV

All Implemented Interfaces:

RDFJS

public class NV
extends Object
implements RDFJS

General representation of an NodeValue for JavaScript. Conversion is to native types where possible, otherwise NV. NV.toString of a URI returns the uri as a string so NV works naturally in Java/Nashorn.

See Also:

fromNodeValue(org.apache.jena.sparql.expr.NodeValue), toNodeValue(java.lang.Object), RDFTerm2Json, for one way conversion JSON.

Method Detail

fromNodeValue

public static Object fromNodeValue(NodeValue nv)

Map an ARQ NodeValue to java/Nashorn representation of a JavaScript object. Native JavaScript types supported are null, string, number and boolean. Otherwise a NV is returned.

toNodeValue

public static NodeValue toNodeValue(Object r)

Map a java/Nashorn representation of a JavaScript object to an ARQ NodeValue. Identified types are null, string, number and boolean and also NV returned by the JavaScript code.
