[rules-users] Count matching facts

I am having a hard time finding an example of what I am trying to do, so maybe someone here could help me. What I am trying to do is determine how many facts fall into the same category. My facts are 'processes' and one of their attributes is a 'name'. My goal is to determine how many processes with the same name are running. The problem is I do not know ahead of time the process names available, I want to determine that set at runtime. Also, once I determine the count for a given name, I do not want to run it again for the other processes that fall in that name category. I think "from collect" is probably what I want to use here, but I am not sure how to grab the names in my Pattern from the fact I am currently iterating on. Thanks. -- View this message in context: http://www.nabble.com/Count-matching-facts-tp15160392p15160392.html Sent from the drools - user mailing list archive at Nabble.com.
