The act_eventList variable provides access to methods that apply to the list of events that have been accepted by a rule.
Both a filter rule and a duplicate rule always have a list of no more than one event because a filter rule is a stateless rule and because a duplicate rule retains only the first analyzed event.
The act_eventCount and act_eventList variables are not valid within a timer rule because a timer rule does not process events.
IEvent second_event = act_eventList.get(1);
