/**
|
|
*
|
|
* The Front Controller is a presentation tier pattern. Essentially it defines a
|
|
* controller that handles all requests for a web site.
|
|
* <p>
|
|
* 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.
|
|
* <p>
|
|
* Typically the requests are mapped to command objects ({@link Command}) which then display
|
|
* the correct view ({@link View}).
|
|
* <p>
|
|
* 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}).
