I would also wish to throw in a samll comment here. It was not my intent either to comment on thread safety in JESS; it has alway been my understandng that it was thread safe. What attracted my eye was that the pattern (which clearly works) appears to manage a resource contention and allocation issue as a side effect rather than explicitly. If this is the case then its long term stability might be at risk should there be implementation changes at some future date. Not knowing enough about JESS per se I may have gone bopping down the wrong path (commonly known as a firm grasp of the wrong end of the stick).

This is indeed a good way to get the grouping semantic we're talking about; I did want to point out that Jess is normally thread-safe anyway even if assertions and rule-firings happen in different threads (just in case anyone got a different impression from your message.) > > alan > --------------------------------------------------------- Ernest Friedman-Hill Distributed Systems Research Phone: (925) 294-2154 Sandia National Labs FAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov -------------------------------------------------------------------- To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)
