Re: [rules-users] Accumulate function

No. You can't use $obs before you bind it (2nd pattern) The binding done for accumulate pattern must be used in some accumulate fonction in order to be seen outside. Instead of trying to fix your rule, may be you can describe (with simple phrases) what you are trying to do ? ------------------------------ *De: *"Matteo Cusmai" <cusmaimatteo(a)gmail.com&gt; *À: *"Rules Users List" <rules-users(a)lists.jboss.org&gt; *Envoyé: *Mardi 22 Mai 2012 12:33:16 *Objet: *[rules-users] Accumulate function Hi all, i am going to use a custom accumulate function like that: rule "CrowdInAreaEvent-event" no-loop when $RFIDReader : SensorFixed(type == Sensor.SENSOR_TYPE_RFID, $coverageArea : areaOfInterest ) not CrowdInAreaEvent( sensor == $RFIDReader, this meets[ 5s ] $obs ) $count : Integer( intValue > 10 ) from accumulate( $obs : RFIDObservation( $tagid : tagid, sensor == $RFIDReader ) over window:time( 60s ) from entry-point lowLevelSensorStream, countDistinct( $tagid ) ); then insert( SituationManager.createCrowdInAreaEvent( "Crowd, number people: " + $count, Event.THREAT_LOW, $coverageArea, $RFIDReader, $count, 60, 10 ) ); end I need to refer $obs object in order to compare timing of new observation with last event. Is it possible to do that? Thanks a lot, Matteo. _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
