Constructor Detail

TSimStdoutPane

public TSimStdoutPane(TVirtualMachine virtualMachine)

Creates a new TSimStdoutPane.

Method Detail

setVirtualMachine

public void setVirtualMachine(TVirtualMachine virtualMachine)

Sets the virtualMachine attached to this TSimStdoutPane.

Parameters:

virtualMachine - The virtualMachine to be attached to this TSimStdoutPane.

getVirtualMachine

public TVirtualMachine getVirtualMachine()

Returns the virtualMachine attached to this TSimStdoutPane.

Returns:

The virtualMachine attached to this TSimStdoutPane.

doCommand

public boolean doCommand(String command,
                         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.
