Constructor Detail

TracePainterDisc

public TracePainterDisc()

Creates an instance with a default disc size of 4.

TracePainterDisc

public TracePainterDisc(int discSize)

Creates an instance with the given disc size.

Parameters:

discSize - the disc size in pixel to use.

Method Detail

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>

Overrides:

endPaintIteration in class 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 ATracePainter

Object.equals(java.lang.Object)

getDiscSize

public int getDiscSize()

Returns the diameter of the discs to paint in pixel.

Returns:

the diameter of the discs to paint in pixel.

hashCode

public int hashCode()

Overrides:

hashCode in class ATracePainter

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>

Overrides:

paintPoint in class 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!

Parameters:

discSize - the diameter of the discs to paint in pixel.

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:

Overrides:

startPaintIteration in class ATracePainter

Parameters:

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