Class Sine

java.lang.Object

org.diirt.datasource.sim.Sine

public class Sine
extends Object

Function to simulate a signal shaped like a sine. The warning limits are set at 80% of the range and the alarm at 90% the range. All values are going to have no alarm status, with the timestamp set at the moment the sample was generated.
