Remarks

Delay queue sensors are separate from timer queue sensors (see OIV.Inventor.Sensors.SoTimerQueueSensor) and provide methods for setting the relative priorities of the sensors in the delay queue (sensors with higher priorities will be triggered first).

Sensors with non-zero priorities are added to the delay queue when scheduled, and are all processed once, in order, when the delay queue is processed, which normally happens as part of your program's main loop (see OIV.Inventor.Win.SoWin.MainLoop() or ()). Typically, the delay queue is processed whenever there are no events waiting to be distributed and there are no timer queue sensors waiting to be triggered. The delay queue also has a timeout to ensure that delay queue sensors are triggered even if there are always events or timer sensors waiting; see OIV.Inventor.SoDB.SetDelaySensorTimeout(OIV.Inventor.SbTime).

Sensors with priority 0 are treated specially. Priority 0 sensors are triggered almost immediately after they are scheduled, before the program returns to the main loop. Priority 0 sensors are not necessarily triggered immediately when they are scheduled, however; if they are scheduled as part of the evaluation of a field connection network they may not be triggered until the evaluation of the network is complete. Also, if a priority 0 sensor is scheduled within the delegatemethod of another priority 0 sensor, it will not be triggered until the delegatemethod is complete (also note that if more than one priority 0 sensor is scheduled, the order in which they fire is undefined).
