Creates a new TSimMachinePane.

Method Detail

addChangeListener

public void addChangeListener(javax.swing.event.ChangeListener listener)

Adds a listener to monitor changes in the state of the switches.

Parameters:

listener - The listener to add to this pane. A null value will cause a NullPointerException.

removeChangeListener

public void removeChangeListener(javax.swing.event.ChangeListener listener)

Removes a listener from this machine. Nothing will happen if no match was found.

Parameters:

listener - The listener to remove from this pane. A null value will cause a NullPointerException.

setVirtualMachine

public void setVirtualMachine(TVirtualMachine virtualMachine)

Sets the virtualMachine attached to this TSimMachinePane.

Parameters:

virtualMachine - The virtualMachine to be attached to this TSimMachinePane.

getVirtualMachine

public TVirtualMachine getVirtualMachine()

Returns the virtualMachine attached to this TSimMachinePane.

Returns:

The virtualMachine attached to this TSimMachinePane.

getAddr

public TWord getAddr()

Returns the TWord derived from the positions of the addr switches.

Returns:

The TWord derived from the positions of the addr switches.

getData

public TWord getData()

Returns the TWord derived from the positions of the data switches.

Returns:

doCommand

public boolean doCommand(java.lang.String command,
                java.lang.Object extraInfo)

Performs a command based on the argument.

Parameters:

command - A string representing the command. Note that pointer equality (not string equality) is tested here, so it is important to use the string constants defined in this class. An IllegalArgumentException will be thrown if the argument is invalid.

Returns:

True iff the command was executed sucessfully.

processComponentEvent
