Constructor Detail

SimpleExerciseSequencer

public SimpleExerciseSequencer(AppSession appSession,
                               List<ExerciseArgumentSetting> givenExerciseList,
                               int timeOut,
                               String bookId)

Instanciate the iterator over the given list of exercises.

Parameters:

appSession -

givenExerciseList - only simply list of string.

Method Detail

exerciseFinished

public void exerciseFinished(String exerciseId,
                             double successRate)

Handler whenever one exercise is finished.

Specified by:

exerciseFinished in class ExerciseSequencer

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

isGoalAchieved

public boolean isGoalAchieved()

Check if the given list is used up, when yes, sequencer can terminate. Otherwise not.

Specified by:

isGoalAchieved in class ExerciseSequencer

Returns:

true if learning goal is achieved false if we still need to continue with showing the next exercise

getNextExercise

public ExerciseArgumentSetting getNextExercise()
                                        throws NoAvailableExercisesException

Returns the next exercise in the list

Specified by:

getNextExercise in class ExerciseSequencer

Returns:

Throws:

NoAvailableExercisesException - if we can't find one
