public class SoPathSensor
extends SoDataSensor
```
Sensor class that can be attached to Open Inventor paths. Path sensors detect changes to paths, calling a callback function whenever the path or any node in the path changes.
The definition of "in the path" is the same as the definition used when applying an action to the path - any node that can possibly affect the node at the end of the path chain is considered in the path. See the SoPath manual page for more information on paths.
See SoDataSensor for general information and code example.
