Questions tagged [controller]
The controller tag is used with questions involving the controller component of the Model View Controller (MVC) design pattern. The controller component accepts input, usually from a user interface, and issues various change and modification requests to the model component and/or the view component controlling the data of the model and how the data is presented. In some cases controller and view are combined into a single component.
