I may have something that can be contributed to commons. I just mentioned this on the lucene list and I was referred here as another place that could use it.
I have written a class that implements Map and uses jdbm, the disk-based BTree (http://jdbm.sf.net) to persistently store its (Serialized) data. It's called PersistentMap so you can program to it in a convenient form and possibly just drop it in as a replacement for any existing Map's (HashMap, TreeMap). Only the ctr is really different (you specify a file name to store to). It's not hard to do a presistent Set or List either. Code is here: http://www.tropo.com/techno/java/jdbm/ The main alternative to jdbm is JISP, which I haven't used: http://www.coyotegulch.com/algorithm/jisp/ Appologies if I missed that commons already has such a thing or if this is the wrong list etc. - Dave -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
