Re: [p2-dev] Contract for compound queryables

[Ian Bull <irbull@xxxxxxxxxxxxxxxxx>]

>From what I recall (this is a bit before my time), when the query mechanism was first introduced, it was decided that all query results (then called collectors) would collect things as Sets (unique).  Last year, I introduced the notion of List based collectors, but this was never used and I don't think our current infrastructure even supports it.

IMHO, this means we have gone back to what was originally decided, all queries should return a set, and thus compound things (like compound queryables) should return a unique set too.

Do others have thoughts on this?

cheers,

Hi,
Is it required for a CompoundQueryable to return a unique set when queried for all elements?
