Class Event

public class Event

extends Sensor

An Event Sensor is used to measure information about instantaneous, point events (events with negligible duration). Programs call the occurred() method each time the measured event occurs, and DMS computes a count value indicating the number of occurrences. An Event sensor contains a count metric.
