抽象工厂模式(Abstract Factory Pattern) 一、 抽象工厂(Abstract Factory)模式 抽象工厂模式是所有形态的工厂模式中最为抽象和最具一般性的一种形态。 为了方便引进抽象工厂模式,引进一个新概念:产品族(Product Family)。所谓产品族,是指位于不同产品等级结构,功能相关联的产品组成的家族。如图: 图中一共有四个产品...

Note that a static factory method is not the same as the Factory Method pattern from Design Patterns [Gamma95, p. 107]. The static factory method described in this item has no direct equivalent in Design Patterns. A class can provide its clients with static factory methods instead of, or...
Singleton pattern with Factory constructors You can implement the singleton pattern using factory constructors like this: the key thing here is that any consuming code is completely oblivious to the fact that we have just implemented the singleton pattern. If we were to continue our mind later or...
FromAsync(Func<AsyncCallback, Object, IAsyncResult>, Action<IAsyncResult>, Object) Creates a Task that represents a pair of begin and end methods that conform to the Asynchronous Programming Model pattern. FromAsync(IAsyncResult, Action<IAsyncResult>, TaskCreationOptions) Creates a Task that...
The Singleton pattern adds functionality by modifying an existing class. The modifications required are: Make the constructor private and add a private static constructor as well. Add a private static read-only object that is internally instantiated using the private constructor. Add a public static ...

Creates a Task that represents a pair of begin and end methods that conform to the Asynchronous Programming Model pattern.
