The invocation handler could also be refactored to handle other operations across multiple method invocations on different object types. 还可以重构调用处理程序,让它处理其他横跨不同对象类型的方法调用的操作。
For example, the proxy class could delegate the method invocation to any other object or even handle it itself. 例如,代理类可以把方法调用委托其他任何对象,甚至是处理程序本身。
