DESCRIPTION

       Node  sensors  detect  changes to nodes, calling a callback function whenever any field of
       the node or, if the node is a group node, any children of the node change.

METHODS

                         SoNodeSensor()
                         SoNodeSensor(SoSensorCB *func, void *data)
          Creation methods. The second method takes the callback function and data to  be  called
          when the sensor is triggered.

                         ~SoNodeSensor()
          Destroys the sensor, freeing up any memory associated with it after unscheduling it.

     void                attach(SoNode *node)
     void                detach()
     SoNode *            getAttachedNode() const
          The  attach()  method  makes this sensor detect changes to the given node. The detach()
          method unschedules this sensor (if it is scheduled) and makes it ignore changes to  the
          scene graph. The getAttachedNode() method returns the node that this sensor is sensing,
          or NULL if it is not attached to any node.
