Returns:

isGoalAchieved

protected boolean isGoalAchieved()

Description copied from class: TutorialExerciseSequencer

Need to be override in sub classes

Specified by:

isGoalAchieved in class TutorialExerciseSequencer

Returns:

exerciseFinished

public void exerciseFinished(String exerciseId,
                             double successRate)

Could be override by sub class.

Overrides:

exerciseFinished in class TutorialExerciseSequencer

successRate - "-1" tells us we don't know about successRate, otherwise, the number the semantic of positive value is defined in implementing classes.

getNextExercise

public ExerciseArgumentSetting getNextExercise()
                                        throws NoAvailableExercisesException

Description copied from class: ExerciseSequencer

Prepare the next exercise. By override this method, make sure you check if goal is achieved by calling isGoalAchieved().

Specified by:
