[windup-dev] Iteration*Managers

[Ondrej Zizka]

Hi,

what's the purpose of having IterationSelectionManager and 
IterationPayloadManager?
I can only see Named~ and TypedNamed.
Wouldn't a simple method overload in SelectionFactory be enough for just 
giving the option of type checking?
Or do we assume some other use case for that?
Also, the names don't fit - it's not manager, rather some kind of 
filter, or getter.

Also, how about splitting SelectionFactory to VarStack and 
CurrentPayloadManager? The variable stack and "current payload" seem to 
be related only indirectly, by concept - at least in the current 
implementation.

And lastly, I'd rename "current payload" to something like "cursor" 
(resembling DB result iteration) or "current item" or "current element" 
(which is how XSLT refers to iterated nodes). Payload rather evokes that 
there's some wrapper around it, which is not.

Thanks,
Ondra
