public class EventBasedCounter extends Counter implements EventProducer, EventListener
The Counter class defines a statistics event counter. It embeds an EventProducer so it can keep listeners informed about new observations, and it listens to external events to be able to receive observations, in addition to the register(...) method.Copyright (c) 2002-2023 Delft University of Technology, Jaffalaan 5, 2628 BX Delft, the Netherlands.
