Detailed Description

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).

SoTimerSensor instances is commonly used to trigger animation updates at a constant framerate.

Constructor & Destructor Documentation

SoTimerSensor::SoTimerSensor ( void  )

Default constructor. Sets up an interval of 1/30th of a second.

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

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

setFunction(), setData()
SoTimerSensor::~SoTimerSensor ( void  )
virtual

Destructor.

Member Function Documentation

void SoTimerSensor::setBaseTime ( const SbTime baseref)

Set the base trigger time.

If you use this method, the trigger times will be on intervals from the given value.

Without an explicitly set base time, the next trigger invocation after a trigger has happened will be on the current time plus the interval time. Note that this will of course cause the timer to drift.

See also
getBaseTime()
const SbTime & SoTimerSensor::getBaseTime ( void  ) const

Returns the base trigger time.

See also
setBaseTime()
void SoTimerSensor::setInterval ( const SbTime intervalref)

Sets the time interval between each time the sensor triggers.

See also
getInterval()
const SbTime & SoTimerSensor::getInterval ( void  ) const

Returns the timer trigger interval.

See also
setInterval()
void SoTimerSensor::schedule ( void  )
virtual

Overrides the virtual schedule() method to be able to set up the base time, if this was not done by the user.

If no base time was set, base time will then equal the current time.

See also
unschedule(), isScheduled()

Reimplemented from SoTimerQueueSensor.

void SoTimerSensor::unschedule ( void  )
virtual

Overrides the virtual unschedule() method to handle unschedule() calls during triggering.

Reimplemented from SoTimerQueueSensor.

void SoTimerSensor::reschedule ( const SbTime schedtime)

Set new trigger time based on the given schedule time, and schedules the sensor for triggering.
