## Detailed Description

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.

## Constructor & Destructor Documentation

## SoAlarmSensor() [1/2]

SoAlarmSensor::SoAlarmSensor | ( | void |  | ) |

Default constructor.

## SoAlarmSensor() [2/2]

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

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

  setFunction(), setData()

## ~SoAlarmSensor()

SoAlarmSensor::~SoAlarmSensor | ( | void |  | ) |

virtual

Destructor.

## Member Function Documentation

## setTime()

void SoAlarmSensor::setTime | ( | const SbTime & | abstime | ) |

Set the time at which the sensor will trigger.

Note that you must manually schedule() the sensor after calling this method.

See also
  setTimeFromNow(), getTime()

## setTimeFromNow()

void SoAlarmSensor::setTimeFromNow | ( | const SbTime & | reltime | ) |

Set the alarm to be triggered at a specified offset from the current time.

Note that you must manually schedule() the sensor after calling this method.

See also
  setTime(), getTime()

## getTime()

const SbTime & SoAlarmSensor::getTime | ( | void |  | ) | const

Returns the trigger time for the alarm as an absolute value from 1970-01-01 00:00:00.

See also
  setTime(), setTimeFromNow()

## schedule()

void SoAlarmSensor::schedule | ( | void |  | ) |

virtual

Put the sensor in the global timer queue.

  unschedule(), isScheduled()
