Hi all,

I'm trying to execute a P2 query that can chase down all IUs resulting from
starting with several features and traversing the tree of IUs and included
features until all dependencies are satisfied.

I found the example of how to construct such a query at
wiki.eclipse.org/Query_Language_for_p2, but can't work out how to run it
against a set of inputs.

It seems that I need an IQueryable to execute against and some way to
specify the set of Features to use as roots.

I've got an IQueryable, (and can successfully createIUAnyQuery() against
it), but haven't been able to work out how to extend this to query for the
subset that is reachable from a set of Features that are being treated as
roots and are available via the IQueryable.

Any pointers to code snippets or anything else would be welcome.


Thanks in advance,

Dave Orme
