public class Counter

extends SimObject

implements Simulatable, java.io.Serializable

Counter - a generic counter for events on SignalStdLogic1164 signals. Possible event types include 'events', 'value 0' ... 'value D', 'rising edge', 'falling edge', '0 hazards', ...

The counter offers data and clear inputs. The counter may also be cleared interactively.

You can specify the color to use at the display via the via the "Hades.Counter.DisplayColor" property in aarrggbb format.

Constructor Detail

Counter

public Counter()

Counter(): simple constructor

Method Detail

setSymbol

public void setSymbol(Symbol s)

Overrides:

setSymbol in class SimObject

buildGUI

public void buildGUI()

buildGUICallbacks

public void buildGUICallbacks()

clearAllCounters

public void clearAllCounters()

clearSelectedCounter

public void clearSelectedCounter()

showSelectedCounter

public void showSelectedCounter()

getCounterValue

public long getCounterValue(int index)

setCounterValue

public void setCounterValue(int index,
                            long value)

getMaxCounterIndex

public int getMaxCounterIndex()

changeName

public void changeName()

write

public void write(java.io.PrintWriter ps)

write the versionID and the currently active counter

Overrides:

write in class SimObject

initialize

public boolean initialize(java.lang.String s)

read the versionID (currently ignored) and the index of the active counter (_event ... _0 ... _D ...)

Overrides:

initialize in class SimObject

configure

public void configure()

Description copied from class: SimObject

create and display a 'ConfigDialog' to set the parameters for a SimObject. The default ConfigDialog for the base class (SimObject) itself is empty except for the 'instance name' of the SimObject.

Overrides:

configure in class SimObject

getPropertySheet

public java.awt.Component getPropertySheet()

Description copied from class: SimObject

return a reference to the 'property sheet' or configuration window for this SimObject. We cast the return value to an AWT Component, but typically you can expect either a hades.gui.PropertySheet or an java.awt.Window (Dialog or Frame).

Overrides:

getPropertySheet in class SimObject

mousePressed

public void mousePressed(java.awt.event.MouseEvent evt)

mousePressed: currently, the Counter defines two mouse click reactions. If clicked in the lower left corner (1200 < y < 2400, 0 < 1500 < x), the counter is cleared. If clicked in the upper left corner, the counter mode is toggled.

Overrides:

mousePressed in class SimObject

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 SimObject

Parameters:

arg - This parameter is ignored by Counter

evaluate

public void evaluate(java.lang.Object arg)

evaluate(): called by the simulation engine on all events that concern this object. The object is responsible for updating its internal state and for scheduling all pending output events.

Specified by:

evaluate in interface Simulatable

Overrides:

evaluate in class SimObject

Parameters:

arg - An arbitrary and unused object

formatPaddedLong

public static java.lang.String formatPaddedLong(long value,
                                                int n_chars)

copy

public SimObject copy()

copy(): create a clone of the current Counter, including its color

Overrides:

copy in class SimObject

getToolTip

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

Description copied from class: SimObject

construct a (short) tool tip message for a SimObject. This method should be overridden as needed.

Specified by:

getToolTip in interface ContextToolTip

Overrides:

getToolTip in class SimObject

toString

public java.lang.String toString()

toString() - the usual info method

Overrides:

toString in class SimObject

main

public static void main(java.lang.String[] argv)

main(): simple selftest of the Counter's GUI
