[stringtemplate-interest] Tree of objects

[Peter Knego]

Hi,

I'm a newbie, so please bare with me. I read the docs and searched the
mailinglist but could not find an appropriate answer.

I have a tree of objects that represent a GUI hierarchy. Classes used
are children of either ViewGroup or View. ViewGroup is a parent of
View. ViewGroup is a container that holds a list other ViewGroups (and
Views, since they are children of ViewGroup). Views are edge nodes
that represent visual elements (buttons, etc..).

This object tree is built dynamically at run-time. The depth of the
tree can vary, usually it's 3-4 levels deep.

I'd like to use ST to create HTML based on the object tree. What
baffles me is how to support non-fixed depth of this tree, which
happens because ViewGroup can contain other ViewGroups.

Simplified example:

class Div{
    public List<Div> subDivs;
}

Please suggest how this can be solved? Is there any example you can
point me to? I read that ST templates can be called recursively (for
handling ViewGroups containg itself), but how do I pass the right
object reference to it?

Thanks for your help,

Peter Knego
