But that's the point. How the component will access it's dependencies?
Through look up I think.
In the general case, yes. However, let's not completely preclude the possibility of a PicoContainer type of initialization (either all in the constructor, or throught setter/getters).
The component initialization protocol will be performed for this
dependent component as it will for any other component - on demand -
don't they? If don't, it will force us to threat them different,
- creating a separate LookupManager - put the real instances of each dependent component there
- praying for someone to dispose them
It doesn't have to be on demand. You can do it all at one time. You will find that the shutdown order is *very* important. I have experienced some bugs where the container locked up on shutdown that went away when we ensured everything was in the proper order.
All components should have their own "LookupManager" so that they only see what they need to see. Fortress is somewhat crippled in that respect.
As to your other two bullets:
- "real" instances--a proxied instance provides additional security, and a natural location to add interceptors (i.e. functions that get called before and after the interface method's call).
- "praying" for disposal--as much as possible we want to avoid "prayer" as a design constraint. Don't get me wrong, I am a regular practicer of prayer, but it has its place. ;P The container is responsible for properly disposing of components when they are no longer needed.
The container ensuring the environment sanity is a good thing, but I can't see how to implement a different behavior for dependents components. Maybe my nighlty studies of Fortress and Merlin show me where I'm wrong.
I am definitely willing to help you through the hurdles. So that I can help bridge the gap, where are you in your understanding of how containers work?
BTW, did you get the mail I sent you RE: getting proper info for your
CVS access?
I didn't. To which email you sent? I don't work for Cimcorp anymore... :-(
Ahh, that is where I sent it. What email is best for you?
