-
-## Intent
-Stores the objects of a single class and provide a global point of access to them. 
-Similar to Multiton pattern, only difference is that in a registry there is no restriction on the number of objects.
-
-## Explanation
-
-In Plain Words
-
-> Registry is a well-known object that other objects can use to find common objects and services.
-
-**Programmatic Example**
-Below is a `Customer` Class
-
-```java
-public class Customer {
-
-  private final String id;
-  private final String name;
-
-  public Customer(String id, String name) {
-    this.id = id;
-    this.name = name;
-  }
-
-  public String getId() {
-    return id;
-  }
-
-  public String getName() {
-    return name;
-  }
-
-}
-```
-
-This registry of the `Customer` objects is `CustomerRegistry`
-```java
-public final class CustomerRegistry {
-
-  private static final CustomerRegistry instance = new CustomerRegistry();
-
-  public static CustomerRegistry getInstance() {
-    return instance;
-  }
-
-  private final Map<String, Customer> customerMap;
-
-  private CustomerRegistry() {
-    customerMap = new ConcurrentHashMap<>();
-  }
-
-  public Customer addCustomer(Customer customer) {
-    return customerMap.put(customer.getId(), customer);
-  }
-
-  public Customer getCustomer(String id) {
-    return customerMap.get(id);
-  }
-
-}
-```
-
-## Class diagram
-![Registry](./etc/registry.png)
-
-## Applicability
-Use Registry pattern when 
-
-* client wants reference of some object, so client can lookup for that object in the object's registry.
-
-## Consequences
-Large number of bulky objects added to registry would result in a lot of memory consumption as objects in the registry are not garbage collected.

-
-将抽象与其实现分离，以便二者可以独立变化。
-
-## 解释
-
-真实世界例子
-
-> 考虑一下你拥有一种具有不同附魔的武器，并且应该允许将具有不同附魔的不同武器混合使用。 你会怎么做？ 为每个附魔创建每种武器的多个副本，还是只是创建单独的附魔并根据需要为武器设置它？ 桥接模式使您可以进行第二次操作。
-
-通俗的说
-
-> 桥接模式是一个更推荐组合而不是继承的模式。将实现细节从一个层次结构推送到具有单独层次结构的另一个对象。
-
-维基百科说
-
-> 桥接模式是软件工程中使用的一种设计模式，旨在“将抽象与其实现分离，从而使两者可以独立变化”
-
-**程序示例**
-
-翻译一下上面的武器示例。下面我们有武器的类层级：

-    enchantment.onDeactivate();

-  public void onDeactivate() {
-    LOGGER.info("Bloodlust slowly disappears.");
-  }
-}
-```
-
-这里是两种层次结构的实践：
-
-```java
-var enchantedSword = new Sword(new SoulEatingEnchantment());
-enchantedSword.wield();
-enchantedSword.swing();
-enchantedSword.unwield();
-// The sword is wielded.
-// The item spreads bloodlust.
-// The sword is swinged.
-// The item eats the soul of enemies.
-// The sword is unwielded.
-// Bloodlust slowly disappears.
-
-var hammer = new Hammer(new FlyingEnchantment());
-hammer.wield();
-hammer.swing();
-hammer.unwield();
-// The hammer is wielded.
-// The item begins to glow faintly.
-// The hammer is swinged.
-// The item flies and strikes the enemies finally returning to owner's hand.
-// The hammer is unwielded.
-// The item's glow fades.
-```

-使用桥接模式当
-
-* 你想永久性的避免抽象和他的实现之间的绑定。有可能是这种情况，当实现需要被选择或者在运行时切换。
-* 抽象和他们的实现应该能通过写子类来扩展。这种情况下，桥接模式让你可以组合不同的抽象和实现并独立的扩展他们。
-* 对抽象的实现的改动应当不会对客户产生影响；也就是说，他们的代码不必重新编译。
-* 你有种类繁多的类。这样的类层次结构表明需要将一个对象分为两部分。Rumbaugh 使用术语“嵌套归纳”来指代这种类层次结构。
-* 你想在多个对象间分享一种实现（可能使用引用计数），这个事实应该对客户隐藏。一个简单的示例是Coplien的String类，其中多个对象可以共享同一字符串表示形式

-## 目的
-
-依赖注入是一种软件设计模式，其中一个或多个依赖项（或服务）被注入或通过引用传递到一个依赖对象（或客户端）中，并成为客户端状态的一部分。该模式将客户的依赖关系的创建与其自身的行为分开，这使程序设计可以松散耦合，并遵循控制反转和单一职责原则。
-
-## 解释
-
-真实世界例子
-
-> 老巫师喜欢不时地装满烟斗抽烟。 但是，他不想只依赖一个烟草品牌，而是希望能够互换使用它们。 
-
-通俗的说
-
-> 依赖注入将客户端依赖的创建与其自身行为分开。
-
-维基百科说
-
-> 在软件工程中，依赖注入是一种对象接收其依赖的其他对象的技术。 这些其他对象称为依赖项。
-
-**程序示例**
-
-先介绍一下烟草接口和具体的品牌。
-
-```java
-public abstract class Tobacco {
-
-  private static final Logger LOGGER = LoggerFactory.getLogger(Tobacco.class);
-
-  public void smoke(Wizard wizard) {
-    LOGGER.info("{} smoking {}", wizard.getClass().getSimpleName(),
-        this.getClass().getSimpleName());
-  }
-}
-
-public class SecondBreakfastTobacco extends Tobacco {
-}
-
-public class RivendellTobacco extends Tobacco {
-}
-
-public class OldTobyTobacco extends Tobacco {
-}
-```
-
-下面是老巫师的类的层次结构。
-
-```java
-public interface Wizard {
-
-  void smoke();
-}
-
-public class AdvancedWizard implements Wizard {
-
-  private final Tobacco tobacco;
-
-  public AdvancedWizard(Tobacco tobacco) {
-    this.tobacco = tobacco;
-  }
-
-  @Override
-  public void smoke() {
-    tobacco.smoke(this);
-  }
-}
-```
-
-最后我们可以看到给老巫师任意品牌的烟草是多么的简单。
-
-```java
-    var advancedWizard = new AdvancedWizard(new SecondBreakfastTobacco());
-    advancedWizard.smoke();
-```
