Method Detail

getInteraction

public org.jdom.Element getInteraction()

Description copied from class: InteractionGenerator

Produce the initial node, where the exercise really starts.

Overrides:

getInteraction in class InteractionGenerator

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: InteractionGenerator

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

Overrides:

getInteraction in class InteractionGenerator

Parameters:

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

Returns:

element found, or null.

oma

public org.jdom.Element oma(org.jdom.Element el1,
                            org.jdom.Element el2,
                            org.jdom.Element el3,
                            org.jdom.Element el4,
                            org.jdom.Element el5)

getAnswerEvaluator

public Evaluator getAnswerEvaluator()
