[aspectj-users] Again Simple Question
|
Hi Adrian,
Thanks for your quick answer on my previous
question. It worked.
I have another question. I hava a big Java API
and I want to "catch" all method calls serialize
method params&values at input, serialize method
params&values at output and also serialize the
returninc object&value of the method call. The params
& returning value can be any type from void, int,
double to String and also complex Class Types from my
API.
What I had written
pointcut whenMethodIsCalled(StatefullParentBean bean):
this(bean) && execution (* *.* (..)) &&
!within(TestAPI);
pointcut topLevelCalls(StatefullParentBean
bean):whenMethodIsCalled(bean) &&
!cflowbelow(whenMethodIsCalled(StatefullParentBean));
I have an
before(StatefullParentBean bean): topLevelCalls(bean)
and also
after(StatefullParentBean bean) : topLevelCalls(bean)
in which I serialize input & output params.
But I want to serialize also the return value. For
this can I use after returning in place of after?
In after returning can I still get the values of the
parameters which the methods have? Or I need both
after & after returning 1 for parameters and the other
for return value?
AspectJ5 knows if I put Object for the returning
value to handle with all types of returning types no
metter if they are void, int, double, String or a
complex type from my API.
Thanks in advance,
Virgil
