Re: [aspectj-users] after advice - change returned value
|
My suggestion would be to use an around around advice, making your
amendments to the value returned from proceed before in turn returning
that value from the around advice. Assuming you are using a
call(Signature) pointcut declaration, the after() returning advice
executes *after* the join point and therefore after the return value of
the method is set on the return of the call ... so it's not changeable
at that point.
Cheers and hope this helps,
Russ

Hi,
I have the following method:
byte[] getData();
I wanna capture this method now with an after-advice. How can I get
the value, which this method returns and change that value?
I know how to do this with arguments and an around-advice (using the
proceed-advice) and I know how to capture the return value of a
method:
void after() returning(byte[] data)
But how is it possible to change the returned value?
Should I use the after-advice(but how then?)? or should I use the
around-advice together with the proceed-statement?
Thanks in advance
Sebastian
