Examples of org.openrdf.repository.RepositoryConnection.prepareQuery()

org.openrdf.repository.RepositoryConnection.prepareQuery()
Prepares a query for evaluation on this repository (optional operation). In case the query contains relative URIs that need to be resolved against an external base URI, one should use {@link #prepareQuery(QueryLanguage,String,String)} instead. @param ql The query language in which the query is formulated. @param query The query string. @return A query ready to be evaluated on this repository. @throws MalformedQueryException If the supplied query is malformed. @throws UnsupportedQueryLanguageException If the supplied query language is not supported. @throws UnsupportedOperationException If the prepareQuery method is not supported by this repository.

    QueryLanguage queryLn = getQueryLanguage(params, response);
    String baseURI = params.getFirstValue(BASEURI_PARAM_NAME);


    try {
      RepositoryConnection connection = RequestAtt.getConnection(request);
      Query query = connection.prepareQuery(queryLn, queryStr, baseURI);
      parseQueryParameters(query, params, connection.getValueFactory());
      return query;
    }
    catch (StoreException e) {
      throw new ResourceException(SERVER_ERROR_INTERNAL, "Failed to prepare query", e);
