Method Detail


public int getSegmentChoice()
Returns the value of the segmentChoice property.

See Also:


public void setSegmentChoice(int segmentChoice)
Sets the value of the segmentChoice property. Legal values are 1 to 4. This property determines the shape of the segment that is repeated to make an approximation of the fractal curve.

segmentChoice - The new value of the segmentChoice property. Should be in the range 1 to 4; otehr values will be silently ignored.


public ActionList getActionsForView(View view)
Adds a submenu that contains commands for selecting the value of the segmentChoice property.

protected Complex[] computeNextLevel(Complex[] hilbertCurve,
                                     int computedLevel)
Description copied from class: RepeatedSegmentFractal
This abstract method computes one approximation level from the previous one, which has already been computed. This abstract method must be defined in any concrete subclass.

Specified by:
computeNextLevel in class RepeatedSegmentFractal
hilbertCurve - This array stores the points that have been computed for the current approximation level. This array can be null, if the computedLevel is zero.
computedLevel - This is the approximation level that has been comptuted to get the points in curvePoints. A zero value for this paramter means that the first, or base level, approximation should be computed.
An array containing the points in the next level approximation of the curve.
