Method Summary

void	configure() configure: display a dialog to specify the Switch instance name, initial output value, and gate propagation delay.
void	elaborate(java.lang.Object arg) elaborate(): This method is called by the simulation engine to initialize the simulation object.
void	evaluate(java.lang.Object arg) evaluate: as interactive Switch events are handled by mousePressed(), this method is only called by the simulation engine whenever our (hidden) toplevel signal changes.
double	getDelay()
java.lang.String	getToolTip(java.awt.Point position, long millis) construct a (short) tool tip message for a logic gate with name, class name, and gate delay.
protected void	initDisplay()
boolean	initialize(java.lang.String s) initialize an Switch from a String, which contains the integer version id, and optionally the start value of this Switch (the latter encoded via StdLogic1164.getChar() values, 'U' 'X' '0' ...
void	setDelay(java.lang.String s)
void	setSymbol(Symbol s)
void	showState()
void	wakeup(java.lang.Object arg) wakeup: this method is currently used to handle "external" events on this Switch via the assign call, which schedules a Wakeup event to update the Switch symbol at the correct simulation time.
void	write(java.io.PrintWriter ps) write the versionID and the start value of this Switch (the latter as StdLogic1164.getChar() value), e.g.

Constructor Detail

Switch

public Switch()

Switch(): simple constructor

Method Detail

getDelay

public double getDelay()

Overrides:

getDelay in class GenericGate

setDelay

public void setDelay(java.lang.String s)

Overrides:

setDelay in class GenericGate

initialize

public boolean initialize(java.lang.String s)

initialize an Switch from a String, which contains the integer version id, and optionally the start value of this Switch (the latter encoded via StdLogic1164.getChar() values, 'U' 'X' '0' ... 'D'), e.g. "1001 U"

Overrides:

initialize in class GenericGate

write

public void write(java.io.PrintWriter ps)

write the versionID and the start value of this Switch (the latter as StdLogic1164.getChar() value), e.g. "1001 Z"

Overrides:

write in class GenericGate

setSymbol

public void setSymbol(Symbol s)

Overrides:

setSymbol in class SimObject

initDisplay

protected void initDisplay()

showState

public void showState()

elaborate

public void elaborate(java.lang.Object arg)

elaborate(): This method is called by the simulation engine to initialize the simulation object.

Specified by:

elaborate in interface Simulatable

Overrides:

elaborate in class GenericGate

Parameters:

arg - This parameter is ignored by Switch

evaluate

public void evaluate(java.lang.Object arg)

evaluate: as interactive Switch events are handled by mousePressed(), this method is only called by the simulation engine whenever our (hidden) toplevel signal changes. Take the toplevel signal value and propagate to our local signal.

Specified by:

evaluate in interface Simulatable

Overrides:

evaluate in class SimObject

Parameters:

arg - an arbitrary object argument

wakeup

public void wakeup(java.lang.Object arg)

wakeup: this method is currently used to handle "external" events on this Switch via the assign call, which schedules a Wakeup event to update the Switch symbol at the correct simulation time. To this end, the "arg" argument is expected to hold a WakeupEvent whose arg member is a StdLogic1164 object.

Specified by:

wakeup in interface Wakeable

configure

public void configure()

configure: display a dialog to specify the Switch instance name, initial output value, and gate propagation delay.

Overrides:

configure in class GenericGate

getToolTip

public java.lang.String getToolTip(java.awt.Point position,
                                   long millis)

Description copied from class: GenericGate

construct a (short) tool tip message for a logic gate with name, class name, and gate delay.

Specified by:

getToolTip in interface ContextToolTip

Overrides:

getToolTip in class GenericGate
