Constructor Detail

InteractionGenerator

public InteractionGenerator()

InteractionGenerator

public InteractionGenerator(LocalUserModel localUserModel)

InteractionGenerator

public InteractionGenerator(LocalUserModel localUserModel,
                            String lang)

Method Detail

setLang

public void setLang(String lang)

getExerciseDocument

public org.jdom.Document getExerciseDocument()

getTheoryId

public String getTheoryId()

getExerciseId

public String getExerciseId()

getParameters

public List getParameters()

setExerciseDocument

public void setExerciseDocument(org.jdom.Document exercise)

setTheoryId

public void setTheoryId(String theoryId)

setExerciseId

public void setExerciseId(String exerciseId)

setParameters

public void setParameters(List parameters)

setMasterGenerator

public void setMasterGenerator(InteractionGenerator masterGenerator)

getInteraction

public org.jdom.Element getInteraction()

Produce the initial node, where the exercise really starts.

Returns:

JDOM element. Can be null only if the exercise item doesn't have a root element.

getInteraction

public org.jdom.Element getInteraction(String id)

Produce an interaction element from the given ID attribute. TODO: document here the basic structure of an interaction element.

Parameters:

id - value of the "id" attribute of the desired element.

Returns:

element found, or null.

getFeedback

public org.jdom.Element getFeedback(String id)

hasAnswerMap

protected boolean hasAnswerMap(org.jdom.Element interaction)

getAnswerEvaluator

public Evaluator getAnswerEvaluator()

Provide an answer evaluator, if this generator requires a custom one. Normally it would be enough with the default evaluator.

Returns:

Evaluator object.
