compareTo
public int compareTo(ATracePainter o)
- Specified by:
compareTo
in interfacejava.lang.Comparable<ATracePainter>
-
discontinue
public void discontinue(java.awt.Graphics g2d)
Description copied from interface:ITracePainter
Invoked 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:
discontinue
in interfaceITracePainter<ATracePainter>
- Parameters:
g2d
- provided in case pending paint operations have to be performed.- See Also:
ITracePainter.discontinue(java.awt.Graphics)
-
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>
- Parameters:
g2d
- provided in case pending paint operations have to be performed.- See Also:
IPointPainter.endPaintIteration(java.awt.Graphics)
-
equals
public boolean equals(java.lang.Object obj)
- Overrides:

Object.equals(java.lang.Object)
-
getPreviousPoint
protected ITracePoint2D getPreviousPoint()
Returns the previous trace point that had to be painted bypaintPoint(int, int, int, int, Graphics, ITracePoint2D)
.This value will be
null
if 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_VALUE
if 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_VALUE
if 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()
- Overrides:

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