Class SineMaker

java.lang.Object
provided.utils.valueGenerator.impl.SineMaker
All Implemented Interfaces:
ISineMaker
public class SineMaker extends Object implements ISineMaker
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.

    Description
    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.

  • Field Details

    • _mid

      private double _mid
      The midpoint of the min and max values.

    • _ampl

      private double _ampl
      The amplitude of the sinusoidal output

    • _delta

      private double _delta
      The amount that _theta is incremented each time, in radians.

    • _theta

      private double _theta
      The current angle used to generate the current sinusoidal value. Initialized to produce the minimum value.

  • Constructor Details

    • SineMaker

      public SineMaker​(double min, double max, double delta)
      The constructor takes several values to control the object's behavior.
      Parameters:
      min - The minimum and initial value to produce.
      max - The maximum value to produce.
      delta - The amount in radians that the generating angle is incremented each time

  • Method Details

    • getDblVal

      public double getDblVal()
      Description copied from interface: ISineMaker
      Returns a different value each time it is called. The value varies smoothly in a sinusoidal fashion, incrementing each time as per the above specified delta angle increase.
      Specified by:
      getDblVal in interface ISineMaker
      Returns:
      the next value as a double

    • getIntVal

      public int getIntVal()
      Description copied from interface: ISineMaker
      Same as getDblVal, but returns the result rounded to the nearest integer. Note that getDblVal and getIntVal are not independent as getIntVal merely calls getDblVal.
      Specified by:
      getIntVal in interface ISineMaker
      Returns:
      the next value as an int
