[jboss-dev-forums] [Design the new POJO MicroContainer] - Spring-int schema support

[alesj]

I'm just going through Spring xml schema and there are a couple of features that need to be discussed if we really want to support them.

First here are some that I think are useful to be added to existing bean metadata support:
 - parent (http://www.springframework.org/docs/reference/beans.html#beans-child-bean-definitions)
 - abstract (same link as parent)

After you have these previous two, there is a 'merge' option on collections:
 - http://www.springframework.org/docs/reference/beans.html#beans-collection-elements
Which is probably trivial to implement.

There are two that fit in the ConfigureAction:
 - autowire (http://www.springframework.org/docs/reference/beans.html#beans-factory-autowire)
 - dependency-check (http://www.springframework.org/docs/reference/beans.html#beans-factory-dependencies)
I already added support for optional 'autowire-candidate' aka 'contextual-injection-candidate'.

'scope' element will probably be handled by our kernel scoping impl - additional API on top of deployers?

And two more which can probably be handled by our aspectized MC configuration:
 - lookup-method (http://www.springframework.org/docs/reference/beans.html#beans-factory-lookup-method-injection)
 - replaced-method (http://www.springframework.org/docs/reference/beans.html#beans-factory-arbitrary-method-replacement)
Kabir?
How to integrate this with Joinpoint instantiation?

Some of them have a 'global' deployment default value.

What's the deal with all those lifecycle, aware, post-callback interfaces:
 - http://www.springframework.org/docs/reference/beans.html#beans-factory-nature
 - http://www.springframework.org/docs/reference/beans.html#beans-factory-extension
We can probably wrap most of them into MC features.
How to get classes into classpath? Meaning, can we ship our own small artifact/jar with just those interfaces?
So that the notion of not needing full blown Spring IoC is still there. ;-)
