Class SineMaker

class SineMaker
extends Object
This class is used to create a sine wave oscillation of an integer value between specified minimum and maximum values. This is accomplished through successive calls to next(). The oscillation rate is controlled by a parameter that sets the angular increment between calls to next().

Variable Index

o dtheta
The angular increment between calls to next(), in radians
o mid
The mid-point of the oscillation, i
o range
The range of the oscillation from mid-point to extrema, i
o theta
The current angular position, in radians

Constructor Index

o SineMaker (int, int, double)
The constructor for SineMaker

Method Index

o next ()
Returns the next value of the sine wave oscillation

Variables

o mid 
private double mid
The mid-point of the oscillation, i.e. the offset zero point.

o range 
private double range
The range of the oscillation from mid-point to extrema, i.e. the amplitude.

o dtheta 
private double dtheta
The angular increment between calls to next(), in radians.

o theta 
private double theta
The current angular position, in radians.

Constructors

o SineMaker 
public  SineMaker(int min, int max, double dtheta)
The constructor for SineMaker. It takes three arguments.

Parameters:
min - The minimum return value for next()
max - The maximum return value for next()
dtheta - The angular increment per call to next()

Methods

o next 
public int next()
Returns the next value of the sine wave oscillation.
