* The Front Controller pattern consolidates request handling through a single handler object ( * {@link FrontController}). This object can carry out the common the behavior such as * authorization, request logging and routing requests to corresponding views. *
* Typically the requests are mapped to command objects ({@link Command}) which then display the * correct view ({@link View}). *
* In this example we have implemented two views: {@link ArcherView} and {@link CatapultView}. These * are displayed by sending correct request to the {@link FrontController} object. For example, the * {@link ArcherView} gets displayed when {@link FrontController} receives request "Archer". When * the request is unknown, we display the error view ({@link ErrorView}). * */ public class App { /** * Program entry point * * @param args * command line args */ public static void main(String[] args) { FrontController controller = new FrontController(); controller.handleRequest("Archer"); controller.handleRequest("Catapult"); controller.handleRequest("foobar"); } }
