Digitizers are component that allow low–level interaction with the digitizing equipment. For example, video channels use video digitizer components, and sound channels use sound input drivers. The programming interface available depends on the type of digitizer you are dealing with. The QTPlgChannelDigitizer defines properties and methods common to any digitizer object; specific functionalities will be provided by its derived classes.

The class has not constructor at all (you can always use the Realbasic common constructor syntax, of course, but you will obtain an usless object). Its destructor, will be implicitly invoked every time one of its derived classes will be destroyed.
a reference to the identifier of the connection to the digitizer component (aka component instance). useful for toolbox programmers
(use with care: you could invalidate the reference causing unpredictable results
(probably an application crash))
