facade

I want to ask what is the reason to use Facade Pattern when access EJB Session Bean. In my Netbeans 6.9.1, if I do New > Sessions Bean for Entity Classes , and let say that I select User entity, then Netbeans would generate this code AbstractFacade.java public abstract class AbstractFacade<T> { private Class<T> entityClass; public AbstractFacade(Class<T> entityClass) { this.entityClass = entityClass; } protected abstract EntityManager getEntityManager(); public void create(T entity) { getEntityManager().persist(entity); } public T edit(T entity) { return getEntityManager().merge(entity); }

I'm confused by the Facades offered by Laravel. The Laravel documentation states: Facades provide a "static" interface to classes that are available in the application's service container . Laravel ships with many facades which provide access to almost all of Laravel's features. Laravel facades serve as "static proxies" to underlying classes in the service container, providing the benefit of a terse, expressive syntax while maintaining more testability and flexibility than traditional static methods. Please help me to understand: Why we really use use Illuminate\Support\Facades ? How to create

I've been researching the difference between these two patterns. I understand that facade encapsulates access to a sub system and mediator encapsulates the interactions between components. I understand that sub system components are not aware of the facade, where as components are obviously aware of the mediator. I'm currently using a facade for encapsulating the method of retrieving configuration information, e.g. App.Config, user setting stored in SQL, Assembly info, etc, and a mediator for navigation between different windows forms. However, most sites point out that the mediator “adds

What is the difference between the Facade, Proxy, Adapter, and Decorator design patterns? I have never read a clear explanation, what's yours? dirkgently Adapter adapts a given class/object to a new interface. In the case of the former, multiple inheritance is typically employed. In the latter case, the object is wrapped by a conforming adapter object and passed around. The problem we are solving here is that of non-compatible interfaces . Facade is more like a simple gateway to a complicated set of functionality. You make a black-box for your clients to worry less i.e. make interfaces simpler

I'm having a little problem with creating a facade model class with Laravel. I have followed http://laravel.com/docs/facades but I guess I'm missing something. I have created a folder in app/models called foo . In that folder I have two files. First file (Foo.php): <?php namespace Mynamespace; class Foo { public function method() { } } ?> Second file (FooFacade.php): <?php use Illuminate\Support\Facades\Facade; class Foo extends Facade { protected static function getFacadeAccessor() { return 'foo'; } } ?> Then I added Foo => 'Mynamespace\Foo' to the aliases array in app/config/app.php and ran
