Method Summary

void	configure() create and display a 'ConfigDialog' to set the parameters for a SimObject.
void	constructDynamicSymbol()
void	constructPorts()
void	evaluate(java.lang.Object arg) evaluate(): get the numerial value i of input A (if defined), and set output bit[i] to 1, all others to 0.
java.lang.String	getToolTip(java.awt.Point position, long millis) construct a (short) tool tip message.
void	initDisplay()
boolean	initialize(java.lang.String s) initialize a RTLIB object from a String which contains the integer version id, the width of the input vector, and the default delay.
boolean	needsDynamicSymbol()
void	setSymbol(Symbol s)
void	setWidth(int _n) we need to override setWidth from GenericRtlibObject, because we need to rebuild our symbol completely, once the width (n_outputs) of the input vector changed.
void	updateSymbol()
void	write(java.io.PrintWriter ps) write the following data to PrintWriter ps: our versionId, the width (n_bits), and the default delay.

BitDecoder

public BitDecoder()

Method Detail

constructPorts

public void constructPorts()

Overrides:

constructPorts in class GenericRtlibObject

needsDynamicSymbol

public boolean needsDynamicSymbol()

Overrides:

needsDynamicSymbol in class SimObject

constructDynamicSymbol

public void constructDynamicSymbol()

Overrides:

constructDynamicSymbol in class SimObject

setSymbol

public void setSymbol(Symbol s)

Overrides:

setSymbol in class GenericRtlibObject

initDisplay

public void initDisplay()

setWidth

public void setWidth(int _n)

we need to override setWidth from GenericRtlibObject, because we need to rebuild our symbol completely, once the width (n_outputs) of the input vector changed.

Overrides:

setWidth in class GenericRtlibObject

evaluate

public void evaluate(java.lang.Object arg)

evaluate(): get the numerial value i of input A (if defined), and set output bit[i] to 1, all others to 0.

Specified by:

evaluate in interface Simulatable

Overrides:

evaluate in class SimObject

Parameters:

arg - an arbitrary object argument

updateSymbol

public void updateSymbol()

Overrides:

updateSymbol in class GenericRtlibObject

write

public void write(java.io.PrintWriter ps)

write the following data to PrintWriter ps: our versionId, the width (n_bits), and the default delay.

Overrides:

write in class GenericRtlibObject

initialize

public boolean initialize(java.lang.String s)

initialize a RTLIB object from a String which contains the integer version id, the width of the input vector, and the default delay.

Overrides:

initialize in class GenericRtlibObject

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 GenericRtlibObject

getToolTip

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

construct a (short) tool tip message.

Specified by:

getToolTip in interface ContextToolTip

Overrides:

getToolTip in class GenericRtlibObject
