Alternative AOP design, alternative aop
Common AOP designs are based on Remoting RealProxy, Emit-based Dynamic proxy, or reflection-based Attribute scan interception. However, we also have an alternative Interception Scheme DynamicObject. As long as we inherit DynamicObject and overload several methods, let's not talk about it. Let's talk about the code.
