  - compareTo
```
public int compareTo(ATracePainter o)
```
    Specified by:
    
    compareTo in interface java.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 interface ITracePainter<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 corresponding ITrace2D.
    
    Specified by:
    
    endPaintIteration in interface IPointPainter<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:
    
    equals in class java.lang.Object
    
    See Also:
    
    Object.equals(java.lang.Object)
  - getPreviousPoint
```
protected ITracePoint2D getPreviousPoint()
```
    Returns the previous trace point that had to be painted by paintPoint(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 by paintPoint(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 by paintPoint(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:
    
    hashCode in class java.lang.Object

  - 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 interface IPointPainter<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!

  - startPaintIteration
```
public void startPaintIteration(java.awt.Graphics g2d)
```
    Description copied from interface: IPointPainter
    
    Invoked to inform implementations that a paint iteration starts for the corresponding ITrace2D.
    
    Specified by:
    
    startPaintIteration in interface IPointPainter<ATracePainter>
    
    Parameters:
    
    g2d - provided in case pending paint operations have to be performed.
