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.

- Method Detail
  - setTask
```
public void setTask(java.lang.Runnable task)
```
    Sets the task to be executed when the sensor is triggered. Execute the task means simply call its run method.
  - schedule
```
public void schedule()
```
  - unschedule
```
public void unschedule()
```
  - isScheduled
```
public boolean isScheduled()
```
    Returns true if this sensor has been scheduled and is waiting in a sensor queue to be triggered. Sensors are removed from the queue before their callback function is triggered.
