69  * This is the usual function that gets overridden to provide data from the Authoring plug-in to the
70  * Sound Engine plug-in. Its goal is to retrieve data (usually from the PropertySet) and write it
71  * in the proper format and order, so the Sound Engine part can retrieve it and use it.
72  *
73  * By design, this function is called to store data, as provided in the plug-in definition XML.
74  *
75  * Because these can be changed at run-time, the parameter block should stay relatively small. For example, it
76  * should only provide basic members. Array sets, full sections, binary data or Object Stores might be
77  * better sent using the GetPluginData function, as the system can then ask to update only a portion
78  * of the parameters.
79  *
80  * The design pattern, in that case, is to call GetPluginData at the end of GetBankParameters with some unique
81  * in_idParam (AK::IAkPluginParam::ALL_PLUGIN_DATA_ID) indicating that you want to send all the parameters
82  * to the data writer.
