Nested Class Summary

static class	ColorIterator.ADefaultStepping Just for protected internal float stepping.
static class	ColorIterator.APiggyBackStepper Base class for stepping models that may step in each direction of the Hue Saturation Luminance color space.
static class	ColorIterator.HSBStepper Performs hue steps until it has walked the whole hue line, then performs a saturation step to start with hue steps again.
static class	ColorIterator.HSStepper Performs hue steps until it has walked the whole hue line, then performs a saturation step to start with hue steps again.
static class	ColorIterator.HueStepper A stepper that walks along the hue line of the color space.
static interface	ColorIterator.ISteppingModel Defines the strategy of walking through the HSB color space.
static class	ColorIterator.LuminanceStepper A stepping model that steps on the luminance line of the HSB color space.
static class	ColorIterator.SaturationStepper A stepping model that steps on the saturation line of the HSB color space.

Constructor Summary

ColorIterator()
Creates an instance that starts with a red and walks the hue line with a ColorIterator.HueStepper.

Method Summary

boolean	hasNext() Returns true if more colors are available.
static void	main(String[] args) Main entry for a test application.
Object	next() Returns instances of java.awt.Color or throws a NoSuchElementException, if iterator has finished.
void	remove() Nothing is done here.
void	reset() Resets the ColorIterator.

public boolean hasNext()

Returns true if more colors are available.

Specified by:

hasNext in interface Iterator

next

public Object next()
            throws NoSuchElementException

Returns instances of java.awt.Color or throws a NoSuchElementException, if iterator has finished.

Specified by:

next in interface Iterator

Returns:

the next available Color.

Throws:

NoSuchElementException - if hasNext() returns false.

reset

public void reset()

Resets the ColorIterator. It will be able to start a new iteration over the colorspace.

remove

public void remove()

Nothing is done here. Do you really want to remove a color from the colorcircle model?

Specified by:

remove in interface Iterator

main

public static void main(String[] args)

Main entry for a test application.
