Hi I would like to introduce a RefCount interface with the methods: incRef(), tryIncRef(), decRef() and getRefCount().
These methods are already declared today on IndexReader and TaxonomyReader (module/facet), and I see no reason why we wouldn't have an interface for doing that. Then it will allow someone to e.g. incRef() a set of RefCount objects or something like that. Also, I think it will be good if IndexSearcher implements this interface too, delegating calls to its underlying indexReader. Because today it seems very awkward to me that if I want to write a SearcherManager-like object, which manages IndexSearchers and essentially keeps track of their references, I need to know that I should call s.getIndexReader().inc/decRef(). Following that, it may be possible to make SearcherManager / SearcherLifetimeManager generic objects which take RefCount objects, but that's for another :). What do you think? Shai
