## Detailed Description

The **SoOneShotSensor** class is a sensor which will trigger once.

Since **SoOneShotSensor** is a subclass of **SoDelayQueueSensor**, it will trigger as soon as either the runtime system is idle, or if it is continually busy it will trigger within a fixed amount of time (this is by default 1/12th of a second, see **SoSensorManager::setDelaySensorTimeout()**).

## Constructor & Destructor Documentation

### SoOneShotSensor::SoOneShotSensor (SoSensorCB \* func, void \* data)

Constructor taking as parameters the sensor callback function and the userdata which will be passed to the callback.
