    • execWithHeFQUIN2

      protected void execWithHeFQUIN2(String fedDescrFile, org.apache.jena.query.Query query)
      This function demonstrates how to use the HeFQUIN engine if you want to process the query result with your program. The implementation here simply prints the result to stdout, but you can also use it in any other way.
