问题 I've ran into the following questions at work, and I don't have the experience or knowledge in order to answer them, I'm hoping that some of you wiser folk may be able to point me in the right direction, any answers will be greatly appreciated!

What is the difference between the Facade and Adapter Pattern?

血红的双手。 提交于 2019-12-20 08:08:58
问题 I've been reading both definitions and they seem quite the same. Could anyone point out what are their differences? Thanks 回答1: The Facade Pattern wiki page has a brief note about this. "An Adapter is used when the wrapper must respect a particular interface and must support a polymorphic behavior. On the other hand, a facade is used when one wants an easier or simpler interface to work with." I heard an analogy that you should think of your universal remote control that you've set up to work

Laravel: Difference App::bind and App::singleton

自古美人都是妖i 提交于 2019-12-18 10:26:19
问题 I get a bit confused over all the nice things laravel has to offer in terms of the IOC container and facades. Since I'm not an experienced programmer it gets overwhelming to learn. I was wondering, what is the difference between these two examples: A facade to 'Foo' and registered in the container via App::bind() A facade to 'Foo' and registered in the container via App::singleton() In my best understanding Foo::method() will be rewritten as $app->make['foo']->method() so in the first example

Why use Facade pattern for EJB session bean

问题 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) {

Java 之 23 种设计模式解析———外观模式(Facade)

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 外观模式是为了解决类与类之家的依赖关系的,像spring一样,可以将类和类之间的关系配置到配置文件中,而外观模式就是将他们的关系放在一个Facade类中,降低了类类之间的耦合度,该模式中没有涉及到接口,看下类图:(我们以一个计算机的启动过程为例) 我们先看下实现类: public class CPU { public void startup(){ System.out.println("cpu startup!"); } public void shutdown(){ System.out.println("cpu shutdown!"); } } public class Memory { public void startup(){ System.out.println("memory startup!"); } public void shutdown(){ System.out.println("memory shutdown!"); } } public class Disk { public void startup(){ System.out.println("disk startup!"); } public void shutdown(){ System.out.println("disk

How do I create a facade class with Laravel?

主宰稳场 提交于 2019-12-17 08:33:12
问题 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

Does Façade leverage the Open-Closed Principle?

寵の児 提交于 2019-12-13 15:36:10
问题 The Wikipedia page (as of today 2013-02-27) for the Open-Closed Principle says that it's realized via inheritance. The name Open/Closed Principle has been used in two ways. Both ways use inheritance to resolve the apparent dilemma, but the goals, techniques, and results are different. The "two ways" refers to Meyer's implementation inheritance and the more common Polymorphic extensions. Anyway, my question is about the Façade pattern, which does not use inheritance. Since it defines an

c++ class design, base class inheritance, or facade design pattern

夙愿已清 提交于 2019-12-12 11:54:18
问题 I have a dumb c++ design question. Is there a way for one class to have the same method names (hence, the same API) of the methods found in several classes? My current situation is that I have a situation where I have classes struct A { void foo() { std::cout << "A::foo" << std::endl;} void boo() { std::cout << "A::boo" << std::endl;} }; struct B { void moo() { std::cout << "B::moo" << std::endl;} void goo() { std::cout << "A::goo" << std::endl;} }; .... imagine possibly more What I really

why does the facade pattern + revealing modular pattern “add security”?

独自空忆成欢 提交于 2019-12-12 01:55:53
问题 REFERENCE According to reference: Below is a more advanced version of the facade pattern that adds security to internal methods. Question: Honestly what do they mean add security? Furthermore, what would be insecure example? Lastly, What would be a simple but real use case for security and this facade + revealing module pattern? var MyModule = ( function( window, undefined ) { // revealing module pattern ftw function MyModule() { function someMethod() { alert( 'some method' ); } function
