Constructor & Destructor Documentation

WatchCommand()

WatchCommand::WatchCommand

(

)

Constructor.

Sets the name of the command to the base class.

Definition at line 50 of file WatchCommand.cc.

                           : SimControlLanguageCommand("watch") {
}

~WatchCommand()

WatchCommand::~WatchCommand ( )

virtual

Destructor.

Does nothing.

Member Function Documentation

execute()

bool WatchCommand::execute ( const std::vector< DataObject > &  arguments )

virtual

Executes the "watch" command.

A watch stops the simulation whenever the given expression changes its value. It is possible to add a condition to a watch, to control when the Simulator must stop with increased precision.

Parameters

arguments

None. The expression is queried from the user.

Returns

True in case simulation is initialized and arguments are ok.

Exceptions

NumberFormatException

Is never thrown by this command.

Implements CustomCommand.

    if (!checkArgumentCount(arguments.size() - 1, 0, 0)) {
        return false;
    }
 
    ExpressionScript expression(NULL, "");
    if (!askExpressionFromUser(expression)) {
        return false;
    }
 
    Watch watch(simulatorFrontend(), expression);
 
    StopPointManager& stopPointManager = 
        simulatorFrontend().stopPointManager();
    return printBreakpointInfo(stopPointManager.add(watch));

helpText()

std::string WatchCommand::helpText ( ) const

virtual

Returns the help text for this command.

Help text is searched from SimulatorTextGenerator.

Returns

The help text.
