Hi everybody,
I have a problem with defadvice's behavior. It looks like you can't add
both a "before" and an "after" advice to the same function.
Here is an example that demonstrates it
(deffunction f ()
(printout t "during f" crlf))
(defadvice before f (printout t "before f" crlf))
(defadvice after f (printout t "after f" crlf))
(f)
It prints:
Jess> (batch "test.clp")
during f
after f
Jess>
Looks like the after overwrote the before one and there is no way to
define both at the same time...
I'm new to Jess so I hope this question is not stupid but i looked in
documentation and in the old mailling-list messages and found no
explaination for it. Is it the intended behaviour (in which case it
would be good to precise it in the doc) or a bug? I'm using the last
Jess71p2.
I needed this to unbind global variables before a bsave and rebind after
the bsave (this variable refers to a java Logger which is not
serializable). I've found another solution wihtout using defadvice but I
find the defadvice more elegant.
Best regards
