Re: [picocontainer-dev] [Paul?] DPC.initForConfig()

I see your point Konstantin.

If we were to imagine ConfigAdapter in the style of InstanceAdapter  
for exclusive use by addConfig(..) what what would it do that is  
different ?

All the work is done in BasicComponentParameter.getTargetAdapter(..)  
- it would be there that we change functionality, if we were to  
change it.

Before we change anything though, what would happen in the following  
scenario ..

    public class NeedsString {
        public NeedsString(String foo) { .. }
    }
    dpc.addComponent(NeedsString.class)
    dpc.addComponent(String.class,"is it me you're looking for?");
    dpc.addConfig("foo","is it me you're looking for?");
    dpc.getComponent(NeedsString.class)
    // ?

Regards,
