In a sense, yes - but its the result of the comparison that is "cached" really.
In the case you described, it is subrule generation. So either side of the "or" is like a separate rule. In version 3, the result of isSameAmount (ie if it was true or false) is "cached". Things will only be re-checked if the "Check" fact changes (and the engine knows about the change). Note that this checking happens as you are asserting objects, not when you "fireAllRules" necessarily. On 7/20/07, Yuri de Wit <[EMAIL PROTECTED]> wrote:
What is the extent of the performance impact caused by using predicate expressions? Check( amount == $amount ) or Check( $amt : amount -> (isSameAmount($amt, $amount) ) My understanding is that once asserted the amount property will be "cached" in the shadow fact, is the result of isSameAmount(...) also cached? thanks, -- yuri _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
