Examples of org.openrdf.query.parser.QueryParser

org.openrdf.query.parser.QueryParser
An RDF query parser translate query strings in some query language to OpenRDF query models.

    InputStream stream = url(queryFile).openStream();
    String query = IOUtil.readString(new InputStreamReader(stream, "UTF-8"));
    stream.close();


    try {
      QueryParser parser = createParser();
      parser.parseQuery(query, null);
      if (MFX_PARSE_ERROR.equals(result)) {
        fail("Negative syntax test failed. Malformed query caused no error.");
      }
    }
    catch (MalformedQueryException e) {
