In general, a wrapper class is any class which "wraps" or "encapsulates" the functionality of another class or component. These are useful by providing a level of abstraction from the implementation of the underlying class or component; for example, wrapper classes that wrap COM components can manage the process of invoking the COM component without bothering the calling code with it. They can also simplify the use of the underlying object by reducing the number interface points involved; frequently, this makes for more secure use of underlying components.

有几种设计模式可以称为包装器类。

请参阅我对“代理、装饰器、适配器和桥接模式有何不同?”

包装器是用于在不同平台之间的两个不同应用程序之间进行通信的类

包装类是一个“包装”其他东西的类，就像它的名字一样。

它更正式的定义是实现适配器模式的类。这允许您将一组api修改为更可用、更可读的形式。例如，在c#中，如果你想使用本机Windows API，它有助于将它包装成一个符合. net设计准则的类。

包装类是用于包装另一个类的类，以便在客户端和被包装的原始类之间添加间接和抽象层。
