    • withPrefixes

      public static String withPrefixes(String str, org.apache.jena.rdf.model.Resource executable)
      Gets a parsable SPARQL string based on a fragment and prefix declarations. Depending on the setting of the flag useGraphPrefixes, this either uses the prefixes from the Jena graph of the given executable, or strictly uses sh:prefixes.
      Parameters:
      str - the query fragment (e.g. starting with SELECT)
      executable - the sh:SPARQLExecutable potentially holding the sh:prefixes
      Returns:
      the parsable SPARQL string
