Not sure I follow how that would work, can you elaborate? The
bindInterceptor signature right now is:
--
void bindInterceptor(Matcher<? super Class<?>> classMatcher,
Matcher<? super Method> methodMatcher,
org.aopalliance.intercept.MethodInterceptor... interceptors);
--
As I understand it (and I haven't used interceptors all that much, so this
could be way off), this means you can only match based on the class/method,
which wouldn't be able to disambiguate based on an instance. Though
thinking about it more, you could have a simple class matcher and have the
interceptors sometimes apply its interception code based on the object it
intercepted. But that would require you preconstruct your instances, so
would only work with singletons, and would be pretty hard if lots of
dependencies were required in the constructor.
