discontinue
Description copied from interface:ITracePainterInvoked to inform the painter that a discontinue in the trace to # paint has occured.This only has to be implemented by painters that collect several points of
IPointPainter.paintPoint(int, int, int, int, Graphics, ITracePoint2D)to draw them as polygons (e.g.:Graphics.drawPolyline(int[], int[], int)).- Specified by:
discontinuein interfaceITracePainter<ATracePainter>- Parameters:
g2d- provided in case pending paint operations have to be performed.- See Also:
-
endPaintIteration
Description copied from interface:IPointPainterInvoked to inform implementations that a paint iteration ends for the correspondingITrace2D.- Specified by:
endPaintIterationin interfaceIPointPainter<ATracePainter>- Parameters:
g2d- provided in case pending paint operations have to be performed.- See Also:

getPreviousPoint
Returns the previous trace point that had to be painted bypaintPoint(int, int, int, int, Graphics, ITracePoint2D).This value will be
nullif no previous point had to be painted.- Returns:
- the previous trace point that had to be painted by
paintPoint(int, int, int, int, Graphics, ITracePoint2D).
-
getPreviousX
public int getPreviousX()Returns the previous X value that had to be painted bypaintPoint(int, int, int, int, Graphics, ITracePoint2D).This value will be
Integer.MIN_VALUEif no previous point had to be painted.- Returns:
- the previous X value that had to be painted by
paintPoint(int, int, int, int, Graphics, ITracePoint2D).
-
getPreviousY
public int getPreviousY()Returns the previous Y value that had to be painted bypaintPoint(int, int, int, int, Graphics, ITracePoint2D).This value will be
Integer.MIN_VALUEif no previous point had to be painted.- Returns:
- the previous Y value that had to be painted by
paintPoint(int, int, int, int, Graphics, ITracePoint2D).

hashCode
public int hashCode() -
paintPoint
public void paintPoint(int absoluteX, int absoluteY, int nextX, int nextY, Graphics g, ITracePoint2D original) Description copied from interface:IPointPainterPaint the point given by absolute coordinates on the given graphic context.The next coordinates are also provided to allow to check how much distance is available for the graphic representation of the current point.
- Specified by:
paintPointin interfaceIPointPainter<ATracePainter>- Parameters:
absoluteX- the ready to use x value for the point to paint.absoluteY- the ready to use y value for the point to paint.nextX- the ready to use next x value for the point to paint.nextY- the ready to use next y value for the point to paint.g- the graphic context to paint on.original- just for information, for painting this should be irrelevant and it should not be changed too!- See Also:

startPaintIteration
Description copied from interface:IPointPainterInvoked to inform implementations that a paint iteration starts for the correspondingITrace2D.- Specified by:
