Constructor Detail

BetaDist

public BetaDist()

Default constructor.

BetaDist

protected BetaDist(java.lang.String name,
                   java.lang.String category)

Constructor for extensions of this class.

Parameters:

name - The name of the method.

category - The (menu) category of the method.

Method Detail

fX

public double fX(double x)

Description copied from class: FunctionalMethod

DOCUMENT ME!

Parameters:

x - DOCUMENT ME!

Returns:

DOCUMENT ME!

See Also:

FunctionalMethod.fX(double)

getBetaP

public double getBetaP()

DOCUMENT ME!

Returns:

The betaP.

getBetaQ

public double getBetaQ()

DOCUMENT ME!

Returns:

The betaQ.

getDistance

public double getDistance()

Returns the distance.

Returns:

The distance.

getFitMethod

public int getFitMethod()

Returns the fitMethod.

Returns:

The fitMethod.

setBetaP

public void setBetaP(double betaP)

DOCUMENT ME!

Parameters:

betaP - The betaP to set.

setBetaQ

public void setBetaQ(double betaQ)

DOCUMENT ME!

Parameters:

betaQ - The betaQ to set.

setDistance

public void setDistance(double distance)

Sets the distance

Parameters:

distance - The distance to set.

setFitMethod

public void setFitMethod(int fitMethod)

Sets the fitMethod

Parameters:

fitMethod - The fitMethod to set.

angleOfPoint

protected double angleOfPoint(int pid)

Calculates the angle of a given point.

Parameters:

pid - The index of the point in the points array.

Returns:

the angle in degrees.

distancedTwoPointMethod

protected void distancedTwoPointMethod(java.awt.Point p)

The fixedTwoPointMethod takes the next point on the actual courve to calculate two points next to it with the distance of the give distance, or the last point of the actual courve.

Parameters:

p - The mouse pointer on the scale.

dynamicPointsMethod

protected void dynamicPointsMethod(java.awt.Point p)

This finds dynamic points using an algorithm, so the user can intuitivly modify the courve.

Parameters:

p - The mouse pointer position.

fit

protected void fit(java.awt.Point point)

Fits the given point into the curve, using the given fit method.

Parameters:

point - The mouse pointer position.

fitCurve

protected void fitCurve(double[] p1,
                        double[] p2,
