All Implemented Interfaces:

java.lang.Cloneable, ColorSource, ContextToolTip, java.io.Serializable, Simulatable

public class LED

extends SimObject

implements Simulatable, ColorSource

an animated light emitting diode.

LED: a simple subclass of SimObject that models an (red/green/yellow/blue) light emitting diode (LED). Note that LEDs are _not_ used as hierarchy connectors - you have to use Opin instances to specify subdesign outputs.

You can specify the exact colors to use for red/green/yellow/blue LEDs via the "Hades.LED.Colors." properties in aarrggbb format, e.g. use "Hades.LED.Colors.red 0x007f0000" for a dark red LED.

Method Detail

setSymbol

public void setSymbol(Symbol s)

Overrides:

setSymbol in class SimObject

write

public void write(java.io.PrintWriter ps)

Overrides:

write in class SimObject

initialize

public boolean initialize(java.lang.String s)

initialize a LED from a String, which should contain the integer version id and the index of the LED's color: 0=red, 1=green, 2=yellow, 3=blue, e.g. 1001 1 for a green LED.

Overrides:

initialize in class SimObject

getColorIndex

public int getColorIndex()

setColorIndex

public void setColorIndex(java.lang.String s)

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

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 LED

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

getColor

public java.awt.Color getColor()

Description copied from interface: ColorSource

get the current value of the Color from this ColorSource

Specified by:

getColor in interface ColorSource

copy

public SimObject copy()

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

Overrides:

copy in class SimObject

toString

public java.lang.String toString()

toString() - the usual info method

Overrides:

toString in class SimObject
