Constructor Detail

TestGenerator

public TestGenerator(java.sql.Connection con,
                     java.util.ArrayList<java.lang.Integer> questionCategoryIDs,
                     java.util.ArrayList<java.lang.Integer> keywordIDs,
                     java.util.ArrayList<java.lang.Integer> questionTypeIDs,
                     int difficultyDesired,
                     int questionCount,
                     int pointsSummDesired,
                     boolean containsPictures)

Parameters:

con - database connection

questionCategoryIDs - list of category IDs which specify the initial set of questions for test generating

keywordIDs - list of keyword IDs which specify the initial set of questions for test generating

questionTypeIDs - types of questions for the test

difficultyDesired - test difficulty that we want to achieve

questionCount - number of questions in the test

pointsSummDesired - the point value of the test we want to achieve

containsPictures - false if the test must not contain questions with pictures

Method Detail

getGeneratedTest

public Test getGeneratedTest()

Returns:

the generatedTest
