Interface IPointPainter<T extends IPointPainter<T>>

Type Parameters:
T - demonstration of unknown comparable and inheritance idiom or bad generics design for this case.
All Superinterfaces:
Comparable<T>, Serializable
All Known Subinterfaces:
IErrorBarPolicy<T>, IPointPainterConfigurableUI<T>, ITracePainter<T>
All Known Implementing Classes:
AErrorBarPolicyConfigurable, APointPainter, ATracePainter, ErrorBarPolicyAbsoluteSummation, ErrorBarPolicyRelative, PointPainterDisc, PointPainterLine, PointPainterVerticalBar, TracePainterConfigurable, TracePainterDisc, TracePainterFill, TracePainterLine, TracePainterPolyline, TracePainterVerticalBar

public interface IPointPainter<T extends IPointPainter<T>> extends Serializable, Comparable<T>
Generic interface for instances that have to render a point in pixel coordinates.

This low level interface is used wherever points have to be painted:

    • endPaintIteration

      void endPaintIteration(Graphics g2d)
      Invoked to inform implementations that a paint iteration ends for the corresponding ITrace2D.

      Parameters:
      g2d - provided in case pending paint operations have to be performed.
    • paintPoint

      void paintPoint(int absoluteX, int absoluteY, int nextX, int nextY, Graphics g, ITracePoint2D original)
      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.

      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

      void startPaintIteration(Graphics g2d)
      Invoked to inform implementations that a paint iteration starts for the corresponding ITrace2D.

      Parameters:
      g2d - provided in case pending paint operations have to be performed.
