You can use $instanceof{} expressions when specify the class of a method, constructor, or field. This is very useful when you want to specify bindings that are driven off of base classes or interfaces.

You CANNOT use $instanceof to describe return types or parameter types yet. We're working on that for the next release.

   <bind pointcut="execution(void $instanceof{SomeInterface}->someMethod())">
       <interceptor class="SimpleInterceptor"/>


To compile and run:
  $ ant
It will javac the files and then run the AOPC precompiler to manipulate the bytecode, then finally run the example. The output should read as follows:
     [java] --- pojo.someMethod(); ---
     [java] <<< Entering SimpleInterceptor type: org.jboss.aop.joinpoint.MethodInvocation
     [java] someMethod
     [java] >>> Leaving SimpleInterceptor
