SoSensor — abstract base class for Inventor sensors

       Sensors  detect  changes  either to time or to Inventor objects in a scene graph, and call a user-defined
       callback function. Sensors are scheduled when the thing they are attached to changes, and sometime  after
       they are scheduled they are triggered, calling the user's callback function.

       SoSensor

voidsetFunction(SoSensorCB*callbackFunction)
          Sets  the  callback  function  that is called when the sensor is triggered. The function must take two
          arguments — user-supplied callback data (of type  void  *)  and  a  pointer  to  the  sensor  that  is
          triggering the function (of type SoSensor *).

     SoSensorCB*getFunction()const
          Returns the callback function that will be called when the sensor is triggered.

     voidsetData(void*callbackData)
          Sets the callback data passed to the callback function.

     void*getData()const
          Returns the user-supplied pointer that will be passed to the callback function.
