Examples of javax.servlet.http.HttpServletRequest.upgrade()

javax.servlet.http.HttpServletRequest.upgrade()
Start the HTTP upgrade process and pass the connection to the provided protocol handler once the current request/response pair has completed processing. Calling this method sets the response status to {@link HttpServletResponse#SC_SWITCHING_PROTOCOLS} and flushes the response.Protocol specific headers must have already been set before this method is called. @throws IOException if an I/O error occurred during the upgrade @throws ServletException if the given httpUpgradeHandlerClass fails to be instantiated @since Servlet 3.1

                    filterChain.doFilter(request, response);
                    break;
                case SUCCESS:
                    LOGGER.fine("Upgrading Servlet request");


                    handler.setHandler(httpServletRequest.upgrade(TyrusHttpUpgradeHandler.class));
                    final String frameBufferSize = request.getServletContext().getInitParameter(TyrusHttpUpgradeHandler.FRAME_BUFFER_SIZE);
                    if (frameBufferSize != null) {
                        handler.setIncomingBufferSize(Integer.parseInt(frameBufferSize));
                    }
