Hi Alex,I did not ask for a composite. I asked for having an explicit method for getting to the nested nodes, just like there is one for getting to the outgoing and incoming edges.The logic of nesting should still be external. In Mondrian we had only one semantics for nesting, and so it was straightforward to maintain the nesting logic inside the element. Now, we have several meaning for nesting, so it is clear that the logic has to be factored out separately.So, yes, a nestedElements variable would do just fine for now.Cheers,Doru_______________________________________________On Mon, Oct 6, 2014 at 3:24 AM, Alexandre Bergel <alexandre.bergel@me.com> wrote:Hi!
I agree with your analysis. However, RTElement should not have an instance variable “children” or “elements". RTElement simply cannot be a composite, as it is not a composite in other frameworks (e.g., RafaelJS).
I’ve spend a couple of hours on working on RTNest. This has become a beast. But I was able to work on it without breaking anything. In Roassal1, I spent too many
nights (and days) on working on the nesting. It is much easier for now.
If we have a variable “children”, may one may rightfully ask why renderOn: does not iterate over it. Why not adding methods such as #add: and #remove: on RTElement. And no… We will not have this. This is too painful to maintain.
I was thinking about adding the list of children as an attribute. Looks like to be the best solution for now.
Cheers,
Alexandre

I cannot build this easily, and this shows me that we have a model problem. This is the side-effect of building custom tools: if the tool costs too much, you might have to think again about the model (it's similar with the relationship between tests and models).
