getActualAnswer

public java.util.Vector getActualAnswer()

Returns the correct answer for this problem. This method is to be called AFTER setupProblem(), generateDelayedFeedback()

setupProblem

public void setupProblem(CodeModel inCode)

Determines the appropriate tutor for the type of this problem, creates the tutor if it does not already exist, updates the tutor with the new problem (unnecessary step since CodeModel is updated in-situ), and sets up the tutor to execute the code so that the client can use the result for immediate feedback or error-flagging so that client can later call getGrade() and getNarration()

generateDelayedFeedback

public void generateDelayedFeedback()

Prompt the current tutor to generate delayed feedback

gradeAnswer
