NodeNot2 and NodeNot2Single both implement the (not) conditional element. NodeNot2Single is an optimized version for the normal case of a single (not); NodeNot2 is used for nested (not)s. > left input adapter Pattern network nodes generally connect to the right input of a join node, except for the first join of a rule; it has a pattern node connected to its left input, as well, where other join nodes are normally collected. The left input adapter just changes a pattern node's output look like a join node's output. > and why you test if that fact class is MAIN:: factname or subclass > of type MAIN:: factname. That sounds like the description of a TECT (Test class type) pattern node from the Rete viewer. I'm not sure how to answer this; that's obviously the primary purpose of the pattern network, to sort facts by their template names. --------------------------------------------------------- Ernest Friedman-Hill Advanced Software 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!)
