问题 In the PHP MVC I'm currently developing, the base controller checks if a user is logged in and, if so, updates its properties (see code). Since these properties are used in various methods of model classes, I'd like to pass them from the base controller to the (base) model. What's the proper way of doing this? class Controller { protected $user_logged_in = false; protected $logged_in_user_id = null; function __construct() { if(isset($_SESSION['user_id'])) { $this->user_logged_in = true; $this

I have various other classes that help make up the MainView each of which extends JPanel . As an example one of these classes is called ParameterView . Should I allow the controller to see

问题 I am integrating Spring MVC into an existing project I have been working on. By integrating, I mean I am rewriting the project using Spring, and using much of my old code. I have already setup the environment and have began working on it. I will refer to this project as ProjectX .

问题 I have a web application built on an MVC design. I have a database which contains a large number of objects (forum threads) which I can't load into memory at once. I now want to display (part of) this collection with different filters in effect (kinda like what stackoverflow does with questions sorted by date, votes, tags etc). Where do I implement the filtering logic? It seems to me that this must go into the model part of the application, as only models interact with the database (in my

问题 I have a System (game) which I try to implement using the architecture Model-View-Presenter. What I have done right now is a while loop in the presenter that calls continuously the view methods for displaying. The way I do this is using a Producer/Consumer pattern, where the View register and event handler for touch events(Android) and produce the corresponding touch imstances, that the presenter consumes in the while loop. Now I would like to use the pattern Observer/Suscriber between The
