196=head4 More details
182 197
198There are three different "images" of the applet. The first is the java or flash applet itself. The object that actually does the work.
199The second is a perl image of the applet -- henceforth the perlApplet -- which is configured in the .pg file and allows a WeBWorK question
200to communicate with the applet. The third image is a javaScript image of the applet -- henceforth the jsApplet which is a mirror of the perlApplet
201but is available to the javaScript code setup and executed in the virtual HTML page defined by the .pg file of the WeBWorK question. One can think of
202the jsApplet as a runtime version of the perlApplet since it can be accessed and modified after the virtual HTML page has been created by
203the PG rendering process.
183 204
205The perlApplet is initialized by $newApplet = new flashApplet( appletName=>'myApplet',..... ); The jsApplet is automatically defined in
206ww_applet_list["myApplet"] by copying the instance variables of $newApplet to a corresponding javaScript object. So $newApplet->{appletName}
207corresponds to ww_applet_list["myApplet"].appletName. (This paragraph is not yet fully implemented :-().
208
209Currently all messages read by the applet are xml text. If some of the code needs to be printed in the HTML header than it is converted
210to a base64 constant and then converted back to text form when it is read by an javaScript subroutine.

214=head4 Requirements for applets
215
216The following methods are desirable in an applet that preserves state in a WW question. None of them are required.
217
218 setState(str) (default: setXML)
219 -- set the current state of the applet from an xml string
220 -- should be able to accept an empty string or a string of
221 the form <XML>.....</XML> without creating errors
222 -- can be designed to receive other forms of input if it is
223 coordinated with the WW question.
224 getState() (default: getXML)
225 -- return the current state of the applet in an xml string.
226 -- an empty string or a string of the form <XML>.....</XML>
227 are the standard responses.
228 -- can be designed to return other strings if it is
229 coordinated with the WW question.
230 setConfig(str) (default: setConfig)
231 -- If the applet allows configuration this configures the applet
232 from an xml string
233 -- should be able to accept an empty string or a string of the
234 form <XML>.....</XML> without creating errors
235 -- can be designed to receive other forms of input if it is
236 coordinated with the WW question.
237 getConfig (default: getConfig)
238 -- This returns a string defining the configuration of the
239 applet in an xml string
240 -- an empty string or a string of the form <XML>.....</XML>
241 are the standard responses.
242 -- can be designed to return other strings if it is
243 coordinated with the WW question.
244 -- this method is used for debugging to ensure that
245 the configuration was set as expected.
246 getAnswer (default: getAnswer)
247 -- Returns a string (usually NOT xml) which is the
248 response that the student is submitting to answer
249 the WW question.
