Method Summary

protected void	clipLineTo(double x, double y) Does the actual painting for clip mode.
void	init(double x, double y) Initialisation with coordinates x and y.
void	init(Point2D.Double p) Same as init(double x, double y), but with a Point2D.Double argument for convenience
protected void	internalLineTo(double x, double y) Calls the clipLineTo and wrapLineTo methods, according to the turtle's edge behavior.
void	lineTo(double x, double y) Calls the internalLineTo(x,y), which does the actual painting.
void	lineTo(Point2D.Double p) Calls the internalLineTo(x,y), which does the actual painting.
protected void	wrapLineTo(double x, double y) Does the actual painting for wrap mode.

Method Detail

init

public void init(double x,
                 double y)

Initialisation with coordinates x and y.

init

public void init(Point2D.Double p)

Same as init(double x, double y), but with a Point2D.Double argument for convenience

internalLineTo

protected void internalLineTo(double x,
                              double y)

Calls the clipLineTo and wrapLineTo methods, according to the turtle's edge behavior. Only overwrite this method when working with another (one that you have defined) edge behaviour.
If you mean to change the manner of drawing lines, do this in the methods clipLineTo() and wrapLineTo().

lineTo

public void lineTo(double x,
                   double y)

Calls the internalLineTo(x,y), which does the actual painting.

lineTo

public void lineTo(Point2D.Double p)

Calls the internalLineTo(x,y), which does the actual painting. This method works the same way as lineTo(double x, double y), but is added for convenience.

clipLineTo

protected void clipLineTo(double x,
                          double y)

Does the actual painting for clip mode. It works already with ScreenCoords! For further comments cf. internalLineTo(double x, double y).

internalLineTo(double, double)

wrapLineTo

protected void wrapLineTo(double x,
                          double y)

Does the actual painting for wrap mode. It works already with ScreenCoords! For further comments cf. internalLineTo(double x, double y).
