DESCRIPTIONData sensors detect changes to scene graph objects (paths, nodes, or fields) and trigger their callback function when the object changes. Data sensors provide a delete callback that is called just before ​the object the data sensor is attached to is deleted; note that the callback should not attempt to modify the object in any way, or core dumps may result. Priority zero data sensors also provide methods ​that can be called in the callback function to determine exactly which node, field, or path caused the sensor to be triggered.
METHODS\f8setDeleteCallback\*(Cr(SoSensorCB *function, void *data)
Sets a callback that will be called when the object the sensor is sensing is deleted. \f8getTriggerNode\*(Cr() const
\f8getTriggerField\*(Cr() const
If this is a priority 0 data sensor, returns the node/field that was modified that caused this sensor to trigger. Returns NULL if the sensor was not triggered because a node/field changed (for example, ​if \f8schedule()\f1 is called on the sensor) or if this sensor is not a priority 0 sensor. Note that because one change to the scene graph may cause multiple nodes or fields to be modified (because of field-to-field ​connections), the node or field returned may not be the only one that changed. \f8getTriggerPath\*(Cr() const
\f8setTriggerPathFlag\*(Cr(SbBool flag)
\f8getTriggerPathFlag\*(Cr() const
If this is a priority 0 data sensor, returns a path to the node that caused this sensor to trigger. Because recreating the path to the node that changed is relatively expensive, \f8setTriggerPathFlag(TRUE)\f1 must be called before the ​sensor is scheduled. If it is not called, or if the sensor wasn't triggered because a node changed, this returns NULL. NULL is also returned if this is not a priority 0 sensor.
