Description

Base interface for IAgTimePeriod and IAgIntervalCollection.

Example

Configure the access analysis time period to specified time instants.

IAgStkObject uav = stkRoot.GetObjectFromPath("/Aircraft/UAV"); 


IAgStkObject sensor = stkRoot.GetObjectFromPath("/Aircraft/UAV/Sensor/UAVSensor"); 


IAgStkObject coloradoSprings = stkRoot.GetObjectFromPath("/Place/ColoradoSprings"); 


 

// For this code snippet, let's use the time interval when the UAV reached min and max altitude values. 


// Note, this assumes time at min happens before time at max. 


IAgCrdnEvent timeOfAltMin = uav.Vgt.Events["GroundTrajectory.Detic.LLA.Altitude.TimeOfMin"]; 


IAgCrdnEvent timeOfAltMax = uav.Vgt.Events["GroundTrajectory.Detic.LLA.Altitude.TimeOfMax"]; 


 

// Set the access time period with the times we figured out above. 


IAgStkAccess access = sensor.GetAccessToObject(coloradoSprings); 


access.AccessTimePeriod = AgEAccessTimeType.eUserSpecAccessTime; 


IAgAccessTimePeriod accessTimePeriod = access.AccessTimePeriodData as IAgAccessTimePeriod; 


 

accessTimePeriod.AccessInterval.State = AgECrdnSmartIntervalState.eCrdnSmartIntervalStateStartStop; 


 

IAgCrdnEventSmartEpoch accessStartEpoch = accessTimePeriod.AccessInterval.GetStartEpoch(); 


accessStartEpoch.SetImplicitTime(timeOfAltMin); 

accessTimePeriod.AccessInterval.SetStartEpoch(accessStartEpoch); 


 

IAgCrdnEventSmartEpoch accessStopEpoch = accessTimePeriod.AccessInterval.GetStopEpoch(); 


accessStopEpoch.SetImplicitTime(timeOfAltMax); 

accessTimePeriod.AccessInterval.SetStopEpoch(accessStopEpoch);

Configure the access interval to the availability time span of the object where access is being computed to.
