Constructor Summary

PredefinedProblemSequencer(java.lang.String inTopic, java.util.Vector conceptsVector, java.lang.String inPredefinedFile)
Warning: conceptsVector limits the templates that are loaded to the concepts listed.

Method Summary

java.util.Vector	getLearningObjectives() Returns the learning objectives in the antecedents of all the problems in this test, and for each learning objective, the template numbers of the problems that have the learning objective in their antecedent.
Template	getNextTemplate() Returns the next template.
java.lang.String	getStatus() Returns the number of problems that remain to be solved
boolean	isSequenceDone() // Returns true if all the templates have been generated at least once Returns false, since the templates are generated in wrap-around fashion

void	resetWrapAround()
void	setWrapAround()

Constructor Detail

PredefinedProblemSequencer

public PredefinedProblemSequencer(java.lang.String inTopic,
                                  java.util.Vector conceptsVector,
                                  java.lang.String inPredefinedFile)

Warning: conceptsVector limits the templates that are loaded to the concepts listed. If PredefinedFile contains template numbers for concepts not in the conceptsVector, those templates will not be loaded and will not be used during the predefined problem sequence. To avoid this, send null as conceptsVector.

Method Detail
