java.lang.Objectutil.SineMaker
public class SineMaker
A utility class that can be used to create smoothly varying sinusoidal numerical data. Note that this is not a singleton class nor does it have static methods as its behavior depends on the minimum, maximum and delta values given to its constructor.
Field Summary | |
---|---|
private double |
_ampl
The amplitude of the sinusoidal output |
private double |
_delta
The amount that _theta is incremented each time, in radians. |
private double |
_mid
The midpoint of the min and max values. |
private double |
_theta
The current angle used to generate the current sinusoidal value. |
Constructor Summary | |
---|---|
SineMaker(double min,
double max,
double delta)
The constructor takes several values to control the object's behavior. |
Method Summary | |
---|---|
double |
getDblVal()
Returns a different value each time it is called. |
int |
getIntVal()
Same as getDblVal, but returns the result rounded to the nearest integer. |
