Method Detail

invoke

Object invoke(Object proxy,
              Method method,
              Object[] args,
              InvocationHandler delegate)
       throws Throwable

This method can intercept the invocation of InvocationHandler either before or after the invocation happens.

The general coding pattern is:

 Object invoke(Object proxy, Method method, Object[] args, InvocationHandler delegate) {
   ... do pre-invocation work ...
   ret = delegate.invoke(proxy,method,args);
   ... do post-invocation work ...
   return ret;
 }
 

But the implementation may choose to skip calling the 'delegate' object, alter arguments, and alter the return value.

Throwable
