Examples of com.vaadin.server.DownloadStream.writeResponse()

com.vaadin.server.DownloadStream.writeResponse()

Writes this download stream to a Vaadin response. This takes care of setting response headers according to what is defined in this download stream ( {@link #getContentType()}, {@link #getCacheTime()}, {@link #getFileName()}) and transferring the data from the stream ( {@link #getStream()}) to the response. Defined parameters ( {@link #getParameterNames()}) are also included as headers in the response. If there's is a parameter named Location, a redirect (302 Moved temporarily) is sent instead of the contents of this stream. @param request the request for which the response should be written @param response the Vaadin response to write this download stream to @throws IOException passed through from the Vaadin response @since 7.0
