Detailed Description

This type of sensor can be used to schedule a one-time callback for some time in the future. The sensor is not guaranteed to be called at exactly that time, but will be called sometime after the specified time.

Constructor & Destructor Documentation

◆ SoAlarmSensor() [1/2]

SoAlarmSensor::SoAlarmSensor ( )

The second method takes the callback function and data to be called when the sensor is triggered.

◆ SoAlarmSensor() [2/2]

SoAlarmSensor::SoAlarmSensor	(	SoSensorCB *	func,
		void *	data
	)

The second method takes the callback function and data to be called when the sensor is triggered.

◆ ~SoAlarmSensor()

virtual SoAlarmSensor::~SoAlarmSensor ( )

virtual

Member Function Documentation

◆ getTime()

const SbTime& SoAlarmSensor::getTime ( ) const

inline

This differs from getTriggerTime() in that this method returns the time the sensor was set to be scheduled, even if it has not yet been scheduled.

Definition at line 113 of file SoAlarmSensor.h.

◆ schedule()

virtual void SoAlarmSensor::schedule ( )

virtual

Reimplemented from SoTimerQueueSensor.

◆ setTime()

void SoAlarmSensor::setTime ( const SbTime & absTime )

You must also call schedule() for the sensor to be triggered. If the sensor is already scheduled, it must be unscheduled and then rescheduled for the change in the trigger time to take effect.

◆ setTimeFromNow()

void SoAlarmSensor::setTimeFromNow ( const SbTime & relTime )
