Re: [rules-users] is there any 'followed by' in Drools as we have in esper

Hi, Please any one let me know if there is any followed by operator in Drools. I want to correlate an event with another event which follows the first event. Esper supports this by using followed by (->) operator. Example in esper: "select r1.name as name,r1.userIPAddress as ipaddress,count(*) as usr_success_count, (r2.getTimeStamp()-r1.getTimeStamp()) as delta_time from pattern" + "[ (every r1=EventRecord(eventNumber=105, eventType='EVENT_REQUEST'))-> " + "(r2=EventRecord(eventNumber=110, eventType='EVENT_SUCCES', id.getCallId()=r1.getId(), name=r1.name)) where timer:within(usr_timeout_interval sec)]"; Can you please providesimilar kind of rule in Drools. -- View this message in context: http://drools.46999.n3.nabble.com/is-there-any-followed-by-in-Drools-as-w...
