Kabir,
Is it possible that the dynamic interceptor has specific granularity of FIELD
only for example. Here is what I meant. I have this jboss-aop.xml setup for
PojoCache:
| <prepare expr="field(*
@org.jboss.cache.pojo.annotation.PojoCacheable->*)" />
|
| <!-- Observer and Observable to monitor field modification -->
| <bind pointcut="
| set(* @org.jboss.cache.pojo.annotation.PojoCacheable->*)
| ">
| <interceptor
class="org.jboss.aspect.patterns.observable.SubjectInterceptor"/>
| </bind>
|
| <introduction class="@org.jboss.cache.pojo.annotation.PojoCacheable">
| <mixin>
| <interfaces>org.jboss.aspect.patterns.observable.Subject</interfaces>
| <class>org.jboss.aspect.patterns.observable.SubjectImpl</class>
| <construction>new
org.jboss.aspect.patterns.observable.SubjectImpl(this)</construction>
| </mixin>
| </introduction>
|
So you see, I declare any @PojoCacheable POJO as "prepare" but I also introduce
it with a Subject interface that has a "notifyObservers" api.
Anyway, when I do this at runtime:
| private void _attachInterceptor(Object pojo, InstanceAdvisor advisor,
Interceptor cacheInterceptor,
| Observer observer)
| {
| advisor.appendInterceptor(cacheInterceptor);
| }
|
adding a CacheInterceptor dynamically (I just want to interceptor for FIELD
access), what happens then is when notifyObservers get called, it will invoke
the CacheInterceptor as well (as in MethodInvocation). In other words,
appendInterceptor has the effect of adding nor just to FieldInvocation but also
MethodInvocation.
Is there anyway around it?
