T5-ioc: Decorator targeting specific interface
Hi,
I was wondering why it is not possible to decorate services with a
specific interface like this;
public static <T extends DAO> T decorateDAOService(Class<T>
serviceInterface, T delegate, Session session)
if I do that tapestry warns me and says;
"Decorator methods must a parameter for the service delegate (i.e.,
the object the created interceptor will delegate to). Method
net.keso.ted.peng5.services.Peng5Module.decorateDAOService(Class, DAO,
Session) does not include such a parameter, and has been ignored.null"
also, "null"? If I remember correctly all warning messages I get ends
with "null" :)

I think this may have to do with what I just (unhappily) discovered
yesterday.. Javassist doesn't appear to really support generics yet.
:(
I'm thinking of moving to asm / cglib for T4. It shouldn't be too hard
as that area was nicely abstracted away into easy to manage areas, but
I'm sure it'll be painful somehow anyways..

It's wierd, because Tapestry IoC is not that picky: it wants to see a
parameter who type matches the service interface type, DAO.
What's your environment? JDK, O/S, etc.?

Re: T5-ioc: Decorator targeting specific interface
Posted by Ted Steen <te...@gmail.com>.
DAO is an interface
as in the example i posted earlier,
public static DAO decorateDAOService(Class<DAO> serviceInterface, DAO
delegate, Session session);
but, as I said, when the warning comes it says
"Decorator methods must a parameter for the service delegate (i.e.,
the object the created interceptor will delegate to). Method
net.keso.ted.peng5.services.Peng5Module.decorateDAOService(Class, DAO,
Session) does not include such a parameter, and has been ignored.null"
it says Class not Class<DAO> so the serviceInterface doesnt "match"
the delegate.

Re: T5-ioc: Decorator targeting specific interface
Posted by Howard Lewis Ship <hl...@gmail.com>.
I think that Tapestry IoC is trying to insist that the parameter be an
interface. Do you have a DAO base class, or a DAO interface?

I guess there maybe could be a problem with the ordering of
decoration, but it is nice to not having to rely on name-magic with
@Match

Re: T5-ioc: Decorator targeting specific interface
Posted by Ted Steen <te...@gmail.com>.
I tried this (where GenericDAO is an interface),
public static DAO decorateDAOService(Class<DAO> serviceInterface, DAO
delegate, Session session);
I think it complains because according to the warning message the
serviceInterface is just a Class, not a Class<DAO> and the delegate is
a DAO. so they dont match.
it would be neat to be able to target a specific interface... :>

I think it's complaining because the T ends up being java.lang.Object,
which isn't an interface.
Don't know about the null, though.null
