Class TracePainterVerticalBar

java.lang.Object
  info.monitorenter.gui.chart.traces.painters.ATracePainter
      info.monitorenter.gui.chart.traces.painters.TracePainterVerticalBar

All Implemented Interfaces:

IPointPainter<ATracePainter>, ITracePainter<ATracePainter>, java.io.Serializable, java.lang.Comparable<ATracePainter>

public class TracePainterVerticalBar
extends ATracePainter

Renders traces by painting a bar with choosable width for each TracePoint2D to show.

Bars are placed around the x value to render: the middle of the bar in x dimension is the exact x value.

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

See Also:

Object.equals(java.lang.Object)

getBarWidth

public int getBarWidth()

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

Object.hashCode()

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!

setBarWidth

public void setBarWidth(int barWidth)

Sets the width of the bars to paint in pixel.

Parameters:

barWidth - the width of the bars to paint in pixel.
