Constructor Detail

TOscilloscope

public TOscilloscope(int _Width,
                     int _Height,
                     double _maxX,
                     double _minY,
                     double _maxY,
                     java.awt.Color _color)

Constructor for the oscilloscope object.

Parameters:

_Width - desired width of the oscilloscope in screen coordinates

_Height - desired height of the oscilloscope in screen coordinates

_maxX - Maximum X value to display in the oscilloscope

_minY - Minimum Y value to display in the oscilloscope

_maxY - Maximum Y value to display in the oscilloscope

_color - Color of the object

Method Detail

setBoundaries

public void setBoundaries(double _maxX,
                          double _minY,
                          double _maxY)

(Re)sets the limits of the oscilloscope in physical coordinates

Parameters:

_maxX - Maximum X value to display in the oscilloscope

_minY - Minimum Y value to display in the oscilloscope

_maxY - Maximum Y value to display in the oscilloscope

initGraphics

public void initGraphics()

Initialize all the graphics. This can not be done in the constructor because some details of the canvas are not know at that time. Should be called in the start() subroutine of the applet, everytime the physical boundaries of the canvas are changed, or if you want to reset the buffers.

setActive

public void setActive()

Activates the simulation.

setInactive

public void setInactive()

Deactivates the simulation.

update

public void update(java.awt.Graphics g)

Called by JVM to redraw the canvas when necessary. Never called by user.

Overrides:

update in class java.awt.Component

Parameters:

g - A graphics object (device context)

redraw

public void redraw()

This function calls the paint() with a graphics object it gets from the canvas. It will only paint if there is a buffer ready to be drawn to screen.

bufferDraw

public boolean bufferDraw()

Called by the user to draw the simulation to an offline buffer if there are any buffers ready.

paint

public void paint(java.awt.Graphics g)

This function paint the buffer to the screen if an offline buffer is ready. It should never be called by the user. Instead call redraw().

Overrides:

paint in class java.awt.Canvas

clearDataStream

public void clearDataStream(int _i)

Clears datastream _i.

Parameters:

_i - Index number for the datastream.

addMeas

public void addMeas(double _dx,
                    double _y,
                    double _z,
                    int _DataStream)

Adds a measurement to datastream _i. you can enter a y and z value belonging to a measurement a time dx farther in time.

newDataStream

public int newDataStream(java.awt.Color _cl)

Opens a new datastream. It returns the datastream number to use for this datastream

BufferReady2String

public java.lang.String BufferReady2String()

Used for debugging.

BufferDrawn2String

public java.lang.String BufferDrawn2String()

Used for debugging.
