Class ServiceParams

java.lang.Object

com.bigdata.rdf.sparql.ast.eval.ServiceParams

public class ServiceParams
extends Object

Helper class for parsing an extracting SERVICE parameters. The SERVICE group graph pattern should consist of zero or triples whose Subject is BD.SERVICE_PARAM. There may be zero or more such triple patterns. The Predicate (key) and Object (val) positions for those triple patterns are extracted into a ServiceParams object. For each key, there may be one or more values.

 SERVICE  {
   bd:serviceParam :key1 :val1 .
   bd:serviceParam :key1 :val2 .
   bd:serviceParam :key2 :val3 .
 }
