Class LocalRangeAtClassNativeFunction

java.lang.Object

org.topbraid.spin.arq.AbstractFunction

org.topbraid.spin.arq.AbstractFunction2

org.topbraid.spin.util.LocalRangeAtClassNativeFunction

All Implemented Interfaces:

org.apache.jena.sparql.function.Function

public class LocalRangeAtClassNativeFunction
extends AbstractFunction2

A native implementation of swa:localRangeAtClass, to optimize performance. The original spin:body is SELECT (COALESCE( spif:walkObjects(?class, rdfs:subClassOf, swa:allValuesFromFunctor, ?property), spif:walkObjects(?class, rdfs:subClassOf, swa:splValueTypeFunctor, ?property), swa:globalRange(?property), swa:defaultRange(?property)) AS ?result) WHERE { }
