Re: [rules-users] Accumulate a on event combinations
Doesn't accumulate have a count by itself? I guess I am trying to figure out
if it is possible to do something like:
rule "Raise alarm"
when
Number( intValue> 5) from
accumulate( $a:EventA( $id:id )
EventB(eventAId=$id, this after [0s,5s] $a);
count($a) )
then
//do stuff
end

An accumulate with explicitly coded init/action/result lets you
accumulate
into
a custom object that provides exactly the information you want: just
that there is a matching number of As and Bs, the counts for As and
Bs, two lists with As and Bs - anything.
See the Expert doc - there's an example for this sort of thing.
