By 'configurable', I mean 'user defined' instead of 'programmer defined'. I know, I can write (and it will work):
rule "Sound the alarm in case temperature rises above threshold" when TemperatureThreshold( $max : max ) Number( doubleValue > $max ) from accumulate( SensorReading( $temp : temperature ) over window:time( 30s ), average( $temp ) ) then // sound the alarm End In this manner, the threshold ($max) is ‘user defined’. Just need to inject a TemperatureThreshold fact with user’s preferred 'max' value. But the 'window:time' is hardcoded forever. I would prefer injecting TemperatureThreshold fact containing a second parameter (windowTime) that could be decide at 'inject time'. That gives a rule similar to the one I had posted originally. But, unfortunately this way, the rule does not compile at all. Passing a variable (like $windowTime) to 'window:time' does not seems to be syntax acceptable. -- View this message in context: http://drools.46999.n3.nabble.com/How-can-we-make-the-over-window-time-parameter-being-configurable-tp4029932p4029982.html Sent from the Drools: User forum mailing list archive at Nabble.com. _______________________________________________ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
