public class TracePainterPolyline extends ATracePainter
A trace painter that increases performance by summing up all points to render for a paint iteration (submitted bypaintPoint(int, int, int, int, Graphics, ITracePoint2D)
invocations betweenstartPaintIteration(Graphics)
andendPaintIteration(Graphics)
) and only invoking only one polyline paint for a paint call of the correspondingChart2D

endPaintIteration
public void endPaintIteration(java.awt.Graphics g2d)
Description copied from interface:IPointPainter
Invoked to inform implementations that a paint iteration ends for the correspondingITrace2D
.- Specified by:
endPaintIteration
in interfaceIPointPainter<ATracePainter>
- Overrides:
endPaintIteration
in classATracePainter
- Parameters:
g2d
- provided in case pending paint operations have to be performed.- See Also:

paintPoint
public void paintPoint(int absoluteX, int absoluteY, int nextX, int nextY, java.awt.Graphics g, ITracePoint2D original)
Description copied from interface:IPointPainter
Paint 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:
paintPoint
in interfaceIPointPainter<ATracePainter>
- Overrides:
paintPoint
in classATracePainter
- 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:

in interfaceIPointPainter<ATracePainter>
- Overrides:
startPaintIteration
