Package WebGUI::Asset::Wobject::Survey::ResponseJSON
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Helper class for WebGUI::Asset::Wobject::Survey. It manages data
|
|
from the user, sets the order of questions and answers in the survey,
|
|
based on forks, and gotos, and also handles expiring the survey
|
|
due to time limits.
|
|
|
|
This package is not intended to be used by any other Asset in WebGUI.

|
|
|
|
Object constructor.
|
|
|
|
=head3 $json
|
|
|
|
Pass in some JSON to be serialized into a data structure. Useful JSON would
|
|
contain a hash with "startTime", "surveyOrder", "responses", "lastReponse"
|
|
and "questionsAnswered" keys, with appropriate values.
|
|
|
|
=head3 $log
|
|
|
|
The session logger, from $session->log. The class needs nothing else from the
|
|
session object.
|
|
|
|
=head3 $survey
|
|
|
|
A WebGUI::Asset::Wobject::Survey::SurveyJSON object that represents the current
|
|
survey.

=head2 createSurveyOrder ( SurveyJSON, [address,address] )
|
|
|
|
This creates the order for the survey which will change after every fork. The survey
|
|
order is to precreate random questions and answers, which also leaves a record or what
|
|
the user was presented with. Forks are passed in to show where to branch the new order.
|
|
|
|
If questions and/or answers were set to be randomized, it is handled in here.
