Constructor Summary

Wave2D()
empty Constructor - initializes the wave with the values of a normal sinus curve

Wave2D(double A, double lambda, double phi)
constructor - takes amplitude, wavelength and phaseshift

Wave2D(double A, double lambda, double phi, double start, double end)
constructor - takes amplitude, wavelength, phaseshift, start- and endpoint

Method Summary

double	calcWave(double x) calculates the amplitude for x
boolean	contains(double x, double y) the wave has no inside this returns always false
boolean	contains(double x, double y, double w, double h) the wave has no inside this returns always false
boolean	contains(java.awt.geom.Point2D p) the wave has no inside this returns always false
boolean	contains(java.awt.geom.Rectangle2D r) the wave has no inside this returns always false
java.awt.Rectangle	getBounds() returns the bounding box
java.awt.geom.Rectangle2D	getBounds2D() returns the bounding box
double	getEnd() gets last point to draw
java.awt.geom.PathIterator	getPathIterator(java.awt.geom.AffineTransform at) returns new WaveIterator
java.awt.geom.PathIterator	getPathIterator(java.awt.geom.AffineTransform at, double flatness) returns new WaveIterator
double	getScale() returns the actual scale
double	getStart() gets first point to draw
boolean	intersects(double x, double y, double w, double h) returns always true - this may be wrong?
boolean	intersects(java.awt.geom.Rectangle2D r) returns always true - this may be wrong?
void	setAmplitude(double A) sets amplitude
void	setEnd(double end) sets last point to draw
void	setPhase(double phi) sets phaseshift
void	setScale(double scale) sets scale - the wave is calculated in 0.1 steps to calculate the x-value of the point where the actual amplitude is to be drawn the current index is multiplicated by this value.
void	setStart(double start) sets first point to draw
void	setWaveLength(double lambda) sets wavelength

Constructor Detail

Wave2D

public Wave2D()

empty Constructor - initializes the wave with the values of a normal sinus curve

Wave2D

public Wave2D(double A,
              double lambda,
              double phi)

constructor - takes amplitude, wavelength and phaseshift

Wave2D

public Wave2D(double A,
              double lambda,
              double phi,
              double start,
              double end)

constructor - takes amplitude, wavelength, phaseshift, start- and endpoint

Method Detail

setEnd

public void setEnd(double end)

sets last point to draw

getEnd

public double getEnd()

gets last point to draw

setStart

public void setStart(double start)

sets first point to draw

getStart

public double getStart()

gets first point to draw

setAmplitude

public void setAmplitude(double A)

sets amplitude

setWaveLength

public void setWaveLength(double lambda)

sets wavelength

setPhase

public void setPhase(double phi)

sets phaseshift

setScale

public void setScale(double scale)

sets scale - the wave is calculated in 0.1 steps to calculate the x-value of the point where the actual amplitude is to be drawn the current index is multiplicated by this value. It is set to 10 by default. A value of 0.0 is NOT allowed

getScale
