public class TimeCompare extends DEActor
input1 or at input2, the event is consumed. The
value that the event carries is insignificant, but the time stamp of the event
is recorded in a local list. Time stamps received at the two input ports are
stored in two different lists. Every time when both lists have data, the
difference between the top elements of the lists is obtained, and is sent to
the output port. This done by subtracting the time stamp of every top event in
the list for input2 with the time stamp of every top event in the
list for input1.
This actor could potentially consume an infinite amount of memory if the arrival rates of events at the two input ports are different, because one of the lists keeps growing.
