So I have created a utility class that will do the basic calculation and return a floating point value of Weight Watcher points but how do I get the input and result displayed using GWT. The Weight Watchers formula is well documented but it should be noted that this is based on earlier patent applications I believe that there are recent amendments, and as I have said previously, UK supermarkets have started putting points calculations on their products, but stating that it has been calculated by them and is not endorsed by Weight Watchers. As I have said previously, I record all of my diet information in Weight Watcher points, but the downside of this is that it is not always possible know the points value of the food that you have consumed - say, when you are out and about. I suppose the easiest next step is to create the points calculator utility that will allow me to use this as the basis of the diet tracking. So the IDE is set-up, the environment works, and the App Engine is ready to rock and roll. In the example above, I am passing the response back as a ServletOutputStream, but I might return the values as a MIME type of "application/xml" - of this, I am not yet decided. ServletOutputStream sos = response.getOutputStream() Now I have got my values I can pass them through the calculate method and return a response: Sfat = new Float(request.getParameter("sfat"))
Kcals = new Float(request.getParameter("kcals")) Map map = new HashMap (request.getParameterMap()) HttpSession session = request.getSession() Įnumeration en = request.getParameterNames() So my doGet() method needs to process the values in the request header: The complete white list of supported classes is here, and it is worth noting that threads, threadpools, and the like are not supported, (mostly because of run away processes, but also for HTTP load balancing).Ĭreation of the servlet is pretty straight forward my new servlet overrides the doGet() methods to process the HTTP request, and returns an HTTP response with the value of the calculation. The Google App Engine uses standard Java Servlets as is mechanism for communication, although there are some limitations on what can be done with the Java language. The time has come to move this into a more scalable approach.
#Devkitpro 3ds development code
So in my last attempt I had set-up a client application that contains all of the code required to calculate points based on kilocalories and saturated fat. "The time has come, the Walrus said, to talk of many things."
