Examples of org.openrdf.rio.RDFWriter

org.openrdf.rio.RDFWriter
An interface for RDF document writers. To allow RDF document writers to be created through reflection, all implementing classes should define at least two public constructors: one with an {@link OutputStream} argument and onewith an {@link Writer} argument.

    setContentType(response, rdfFormat);
    setContentDisposition(model, response, rdfFormat);


    OutputStream out = response.getOutputStream();
    try {
      RDFWriter rdfWriter = rdfWriterFactory.getWriter(out);
      GraphQueryResult graphQueryResult = (GraphQueryResult)model.get(QUERY_RESULT_KEY);
      QueryResultUtil.report(graphQueryResult, rdfWriter);
    }
    catch (QueryEvaluationException e) {
      logger.error("Query evaluation error", e);
