软件架构23种设计模式.docx

23种设计模式及解释（中英文对照）1、抽象工厂模式(Abstract Factory Pattern)：Provide an interface for creating families of related or dependent objects without specifying their concrete classes.（为创建一组相关或相互依赖的对象提供一个接口，而且无需指定它们的具体类。）建造者模式(Builder Pattern)：Separate the construction of a complex object form its representation so that the same construction process can create different representations.（将一个复杂对象的构建与它的表示分离，使得同样的构建过程可以创建不同的表示。）。原型模式(Prototype Pattern) ：Specify the kinds of objects to create using a prototypical instance, and create new objects by copying this prototype.（用原型实例指定创建对象的种类，并且通过拷贝这些原型创建新的对象。）工厂方法模式(Factory Method Pattern) :Define an interface for creating an object,but let subclass decide which class to instantiate.Factory Method lets a class defer instantiation to subclass.（定义一个用于创建对象的接口，让子类决定实例化哪一个类。工厂方法是一个类的实例化延迟到其子类。）单例模式（Singleton Pattern）：Ensure a class has only one instance, and provide a global point of access to it.（确保某一个类只有一个实例，而且自行实例化并向整个系统提供这个实例。）6、适配器模式（Adapter Pattern）Convert the inface of a class into another interface clients expect.Adapter lets classes work together that couldnt otherwise because of incompatible interface.（将一个类的接口变换成客户端所期待的另一种接口，从而使原本因接口不匹配而无法在一起工作的两个类能够在一起工作。）7、桥接模式(Bridge Pattern)Decouple an abstraction from its implementation so that the two can vary independently.（将抽象和实现解耦，使得两者可以独立的变化。）8、组合模式(Composite Pattern)Compose objects into tree structure to represent part-whole hierarchies.Composite lets clients treat individual objects and compositions of objects uniformly.（将对象组合成树形结构以表示“部分-整体”的层次结构，使得用户对单个对象和组合对象的使用具有一致性。）9、装饰模式(Decorator Pattern)Attach additional responsibilities to an object dynamically keeping the same interface.Decorators provide a flexible alternative to subclassing for extending functionality.（动态地给一个对象添加一些额外的职责。就增加功能来说，装饰模式相比生成子类更为灵活。）10、外观模式或门面模式(Facade Pattern)Provide a unified interface to a set of interface in a subsystem.Facede defines a higher-level interface that makes the subsystem easier to use.(要求一个子系统的外部与其内部的
