[picocontainer-dev] Decorator with 2.x ?

[Grégory Joseph]

Hi list,

Is there any way to use Decorated with 2.x without using Decorating ?
Point is, I want to use a certain adapter and a certain Decorator on
only a limited set of components I'm registering, and it seems like
creating my container with the Decorating factory will have all my
components decorated.

If org.picocontainer.behaviors.Decorated.Decorator was public, I guess
I could do what I want here, but maybe I'm look at it the wrong way,
and there's another method I could use ?

I'm essentially trying to decorate components, bean-style, based on an
existing mechanism (which loads those values of a JCR repository, if
you must know) - so while I know where those values come from at
registration time, I have no idea what they (add to that the fact that
I need to proxy those objects because said values can change over
time;))

Thanks for any hint,

One has to subclass Decorating and implement a Decorator I think.

You could easily bake conditional logic into your Decorating subclass that
would do what you want - right ?

See that I did some work on the site - http://picocontainer.github.com/ ?
Its almost ready to flip the switch. This weekend perhaps I'll merge from
2.x to 3.x where needed and address the outstanding questions.

Hey,

Yeah, after I sent the email and went out for a few minutes, I
realized I could do this:
final Decorating decorating = new Decorating() {
public void decorate(Object instance) {
System.out.println("HELLO " + instance);
}
};
pico.addAdapter(
decorating.createComponentAdapter(new
NullComponentMonitor(), new NullLifecycleStrategy(), new Properties(),
moduleClass, moduleClass, null)
);

... as you might guess, I'm not too happy about the CM and LCS bits,
I'd like to "get them" from my current pico.

Not really (although I haven't given it much thought), the components
I'm decorating have no specific interface or annotation to
differentiate them, they're just registered from a different source...

Ha cool, no more 404 images ;) Had been a while since I seen it. HA!
and I see the navigation changed. I'm still kind of missing a high
level navigation, either on the side or the top, though.
