java.lang.String	getScoreString() Gets the reached score in points of hundred (x of 100)
void	load(java.util.HashMap v) Loads this evaluator from a HashMap-representation, that was readed from a xml-file.
void	log(FeedbackObject fo) Logs an FeedbackObject the evaluator needs to evaluate a processed exercise.
void	log(int id) Logs specific states that are reached by the student in FaultMode.
void	postProcessing(java.util.Vector v) An exercise-mode like FaultMode needs to configurate some values after loading of the exercise, and this is done in this method.

evaluate

public void evaluate(OperationRecorder or)

Evaluates a total processed exercise

Parameters:

or - OperationRecorder

log

public void log(FeedbackObject fo)

Logs an FeedbackObject the evaluator needs to evaluate a processed exercise. Mostly this is a FeedbackObject, which contains an error that was made.

Parameters:

fo - FeedbackObject

log

public void log(int id)

Logs specific states that are reached by the student in FaultMode. E.g.: False chosen type of failure

Parameters:

id - FaultEvaluator-ID

Gets a string-html-representation of the errors made, with diverse statistics.

Returns:

string-html-represenation of the errors made

save

public java.util.HashMap save()

Converts the results of the evaluator in a HashMap-representation for saving-purposes.

Returns:

HashMap-representation of the results

load

public void load(java.util.HashMap v)

Parameters:

v - HashMap-representation of the results
