Hi

I would like to write a function such that several round advices can call.
Inside the function proceed() method needs to be called. Can I cast
thisJoinPoint to ProceedingJoinPoint and pass it to the function within
round advice?

thanks

Even if you cast to ProceedingJoinPoint, this will not work (at least not
in ajdt 1.5).

My workaround for this:

void around(): ... {
Runnable proceed = new Runnable() {
public void run() {
proceed();
}
};

myFunction( proceed );
}

void myFunction( Runnable proceedingJoinPoint ) {
...
proceed.run();
}

I analysed this a while ago and I came to the conclusion that there were
something unbound (maybe a bug), such that
ProceedingJoinPoint.proceed(...) will fail when just cast from a
JoinPoint...
