public class CompositeExercise
extends Static

This is an internal exercise composer, similar to exercise sequencer. As opposed to Exercise Sequencer gives more control on the knowledge representation level to the author to design his sequencing strategies also manually, which Exercise Sequencer would not do.

Method Detail

getInteraction

public org.jdom.Element getInteraction()

Description copied from class: Static

Produce the initial node, where the exercise really starts.

Overrides:

getInteraction in class Static

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)

Description copied from class: Static

Produce an interaction element from the given ID attribute.

Overrides:

getInteraction in class Static

Parameters:

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

Returns:

element found, or null.

initGenerator

public InteractionGenerator initGenerator(String generatorName)

generateRandomId

public static String generateRandomId()

getAnswerEvaluator

public Evaluator getAnswerEvaluator()

Description copied from class: InteractionGenerator

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

Overrides:

getAnswerEvaluator in class InteractionGenerator

Returns:

Evaluator object.
