QuestionsFromDatabase

public QuestionsFromDatabase()

Method Detail

setRandomizeQuestionOrder

public void setRandomizeQuestionOrder(boolean theRandomize)

getCacheRandomQuestionOrder

public boolean getCacheRandomQuestionOrder()

Returns:

Returns whether the random question order is cached -- if it's cached, as it is by default, the order will only randomize once per user login, so for each user that logs in they will only see the questions in one order (this is cached by session, so if they log out and log back in, they'll get a different order). Useful when you have a set of randomized questions showing more than once.

setCacheRandomQuestionOrder

public void setCacheRandomQuestionOrder(boolean cacheRandomQuestionOrder)

Parameters:

cacheRandomQuestionOrder - The cacheRandomQuestionOrder to set.

setTable

public void setTable(java.lang.String theTable)

Deprecated. Do not use this anymore. It is obsolete and will be ignored -- there is only one table now.

Parameters:
