Hi all, I've implemented IEditableCollection support for ninjudd's PersistentOrderedSet. But when using that, my application delivered wrong results. See <87hbb6c4qf....@member.fsf.org> and follow-ups.
I was able to track it down to the strangeness in the subject: (.contains (transient (hash-set)) foo) returns true for any object foo, that is, the empty transient hash-set contains everything. The above clojure code is equivalent to this java code, which I used in the PersistentOrderedSet extension: ((ITransientSet) PersistentHashSet.EMPTY.asTransient()).contains(o) For now, I worked around this strange behavior by checking the count() of the TransientHashSet backing my TransientOrderedSet implementation in addition to contains(). But anyway: Is that behavior intended and facilitated internally somehow? If so, is there some documentation about the rationale?
