dynamic proxy classes的意思|示意

Unfortunately, using dynamic proxy classes does have one major drawback: performance.

不幸的是，使用动态代理类确实有一个重要不足：性能。

Method invocations on dynamic proxy classes do not perform nearly as well a direct method call on objects.

对动态代理类的方法调用，不会像直接调用对象的方法那样好。

Dynamic proxy classes have many USES within a business object framework other than simply validating methods in a uniform way.

动态代理类在业务对象框架中有许多用途，不仅仅是用一致的方式对方法进行验证。

Using dynamic proxy classes for validation is a simple and effective way to decouple validation routines from your application's core business logic.

使用动态代理类进行验证是从应用程序的核心逻辑去耦验证程序的简单而有效的方法。

Dynamic proxy classes have many interesting USES within an application, one of which is to effectively handle pre - and post-method invocation operations in a uniform fashion.

动态代理类有许多应用程序中使用的接口，其中一个可以用统一的方式有效地处理方法前和方法后的调用操作。

Dynamic proxy classes give us a way to easily handle validation on any method in a uniform way, while completely separating all of the validation logic from the core business logic.

动态代理类给了我们一种以统一方式方便地处理任何方法上的验证途径，同时把所有的验证逻辑完全与核心业务逻辑分离开。
