public class SoSensor
extends Inventor

Abstract base class for Open Inventor sensors. Sensors detect changes either to time or to Open 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.
