public class FaultEvaluator
extends Evaluator

The automatic evaluator of FaultMode-exercises

Author:

Markus Krebs

Field Summary

static int	CORRECT_MODE ID that defines that the student has found the first failure, and selected the correct failure-type, and is currently specifying what the correct suboperation is.
static int	FALSE_CORRECT ID that defines that the student thought that a correct operation was incorrect.
static int	FALSE_FAILURE_TYPE_SELECTED ID that defines that the student selected the false type of the failure.
static int	FALSE_NOT_FIRST ID that defines that the student found a failure, but it was not the first failure.
static int	FIRST_FAILURE_FOUND ID that defines that the student found the first failure
static int	GIVE_UP ID that defines that the student given up the exercise,
static int	SEARCH_FAILURE ID that defines that the student is in search-the-failure-mode

Constructor Summary

FaultEvaluator()
Creates a FaultEvaluator

Method Summary

void	evaluate(OperationRecorder or) Evaluates a total processed exercise
java.lang.String	getHTMLMessage() Gets a string-html-representation of the errors made, with diverse statistics.
int	getState() Gets the current state the student reached
void	load(java.util.HashMap hm) 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) Calculates the maximal reachable points.
java.util.HashMap	save() Converts the results of the evaluator in a HashMap-representation for saving-purposes.
void	setState(int id)

Method Detail

postProcessing

public void postProcessing(java.util.Vector v)

Calculates the maximal reachable points. This must be calculated before the student works on the exercise.

Overrides:

postProcessing in class Evaluator

Parameters:

v - Vector of the exercise-todo-operations

See Also:

Evaluator.postProcessing(java.util.Vector)

evaluate

public void evaluate(OperationRecorder or)

Description copied from class: Evaluator

Evaluates a total processed exercise

Overrides:

evaluate in class Evaluator

Parameters:

or - OperationRecorder

log

public void log(FeedbackObject fo)

Description copied from class: Evaluator

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

Overrides:

log in class Evaluator

Parameters:

fo - FeedbackObject

log

public void log(int id)

Description copied from class: Evaluator

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

Overrides:

log in class Evaluator

Parameters:

id - FaultEvaluator-ID

See Also:

SEARCH_FAILURE, FIRST_FAILURE_FOUND, FALSE_CORRECT, FALSE_NOT_FIRST, FALSE_FAILURE_TYPE_SELECTED, CORRECT_MODE

getHTMLMessage

public java.lang.String getHTMLMessage()

Description copied from class: Evaluator

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

Overrides:

getHTMLMessage in class Evaluator

Returns:

string-html-represenation of the errors made

getState

public int getState()

Gets the current state the student reached

Returns:

state-id

See Also:

SEARCH_FAILURE, FIRST_FAILURE_FOUND, FALSE_CORRECT, FALSE_NOT_FIRST, FALSE_FAILURE_TYPE_SELECTED, CORRECT_MODE

setState

public void setState(int id)

save

public java.util.HashMap save()

Description copied from class: Evaluator

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

Overrides:

save in class Evaluator

Returns:

HashMap-representation of the results

load

public void load(java.util.HashMap hm)

Description copied from class: Evaluator

Loads this evaluator from a HashMap-representation, that was readed from a xml-file.

Overrides:

load in class Evaluator

Parameters:

hm - HashMap-representation of the results
