How to find instanceof return type? [message #825632]

I have the following @Pointcut with an annotation:
@Pointcut(value="execution(@MyAnnotation * *(" + "MyMessage,..)) &&" +
args(m,..) && @annotation(myanno)")
public void messageProcessing(MyAnnotation myanno, MyMessage msg) {}

@After(value="messageProcessing(myanno, msg), argNames="myanno, msg")
public void afterMessageProcess(MyAnnotation myanno, MyMessage msg) {
// -- do something
}

What I also want is if the return type of the method is of type say, 'X' then do something with the X.

Appreciate your help,

Take a look at the AfterReturning annotation, described here: http://www.eclipse.org/aspectj/doc/released/adk15notebook/ataspectj-pcadvice.html#advice

which allows you to capture the return value. (you are likely to get faster answers on the regular mailing lists that on this forum).

cheers,
Andy
