Detailed Description

Implementation of the "nexti" command of the Simulator Control Language.

Definition at line 47 of file NextiCommand.hh.

Constructor & Destructor Documentation

NextiCommand()

NextiCommand::NextiCommand

(

)

Constructor.

Sets the name of the command to the base class.

Definition at line 55 of file NextiCommand.cc.

                           : 
    SimControlLanguageCommand("nexti") {
}

~NextiCommand()

NextiCommand::~NextiCommand ( )

virtual

Destructor.

Does nothing.

Member Function Documentation

execute()

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

virtual

Executes the "nexti" command.

Advances simulation to the next machine instructions in current procedure. If the instruction contains a function call, simulation proceeds until control returns from it, to the instruction past the function call. The count argument gives the number of machine instruction to simulate.

Parameters

arguments

The count of steps (default is one step).

Returns

True in case simulation is initialized and arguments are ok.

Exceptions

NumberFormatException

Is never thrown by this command.

Implements CustomCommand.

    const int argumentCount = arguments.size() - 1;
    if (!checkArgumentCount(argumentCount, 0, 1)) {
        return false;

        return false;
    }
 
    unsigned int stepCount = 1;
    if (argumentCount == 1) { 
        if (!checkPositiveIntegerArgument(arguments[1])) {
            return false;
        }
        stepCount = arguments[1].integerValue();
    }        
    
    simulatorFrontend().next(stepCount);
        
    printNextInstruction();

helpText()

std::string NextiCommand::helpText ( ) const

virtual

Returns the help text for this command.

Help text is searched from SimulatorTextGenerator.

Returns

The help text.
