Classes¶

class SoAlarmSensor
The SoAlarmSensor class is a sensor which will trigger once at a specified time.

SoAlarmSensor provides a convenient way of setting up triggers for jobs which should be executed only once when they are scheduled. " class SoDataSensor
The SoDataSensor class is the abstract base class for sensors monitoring changes in a scene graph.

If you need to know when a particular entity (as a field or a node) changes, subclasses of SoDataSensor can be used to monitor the entity and notify you when it changes. " class SoDelayQueueSensor
The SoDelayQueueSensor class is the abstract base class for priority scheduled sensors.

Delay queue sensors are invoked upon various events not related to time occurrences. See documentation of subclasses to see which types of events can be surveilled by the builtin sensor types. " class SoFieldSensor
The SoFieldSensor class detects changes to a field.

Attach a field to a sensor of this type to put it under surveillance, so you can act upon changes to the field. " class SoIdleSensor
The SoIdleSensor class is a sensor which will trigger as soon as the application is idle.

An SoIdleSensor differs from an SoOneShotSensor in that it will not trigger if the delay queue processing is occurring due to the delay queue timeout, but only when the application is idle. " class SoNodeSensor
The SoNodeSensor class detects changes to nodes.

Attach a node to a sensor of this type to put it under surveillance, so you can act upon changes to the node. " class SoOneShotSensor
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 run-time 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()). " class SoPathSensor
The SoPathSensor class detects changes to paths.

If you need to know when a path changes (i.e. nodes in the path has been removed, or new nodes is added), use this sensor to get a notification. " class SoSensor
The SoSensor class is the abstract base class for all sensors.

Sensors is a mechanism in Coin for scheduling jobs to be run upon specific events. The events in question could be particular points in time, or changes to entities in the scene graph. " class SoSensorManager
The SoSensorManager class handles the sensor queues.

There are two major sensor types in Coin, 'delay' sensors and 'timer' sensors: " class SoTimerQueueSensor
The SoTimerQueueSensor class is the abstract base class for sensors triggering on certain timer events.

Timer sensors triggers upon specific points in time. " class SoTimerSensor
The SoTimerSensor class is a sensor which will trigger at given intervals.

Use sensors of this class when you want a job repeated at a certain interval, without explicitly needing to reschedule the sensor (i.e. SoTimerSensor automatically re-schedules itself after it has been triggered). "
