Description

User-specified time period for the chain.

Public Methods

This property is deprecated. Use the TimeInterval property to configure the time interval. The user-specified time period. Start/Stop use DateFormat Dimension.

Public Properties

Start	This property is deprecated. Use the TimeInterval property to configure the time interval. Start Time: beginning of the user-specified time period for the chain. Uses DateFormat Dimension.
Stop	This property is deprecated. Use the TimeInterval property to configure the time interval. Stop Time: end of the user-specified time period for the chain. Uses DateFormat Dimension.
TimeInterval	Allows configuring the time interval.

Example

Define and compute a chain (advance)

[C#] Copy Code

// Remove all previous accesses 


chain.ClearAccess(); 

 

// Add some objects to chain 


chain.Objects.Add("Facility/fac1"); 

chain.Objects.Add("Satellite/sat1"); 

chain.Objects.Add("Satellite/sat2"); 

chain.Objects.Add("Aircraft/air1"); 

 

// Configure chain parameters 


chain.AutoRecompute = false; 

chain.EnableLightTimeDelay = false; 

chain.TimeConvergence = 0.001; 

chain.DataSaveMode = AgEDataSaveMode.eSaveAccesses; 


 

// Specify our own time period 


chain.SetTimePeriodType(AgEChTimePeriodType.eUserSpecifiedTimePeriod); 


 

// Get chain time period interface 


IAgChUserSpecifiedTimePeriod chainUserTimePeriod = chain.TimePeriod as IAgChUserSpecifiedTimePeriod; 


chainUserTimePeriod.SetTimePeriod("1 Jul 2005 12:00:00", "2 Jul 2005 12:00:00"); 


 

// Compute the chain 


chain.ComputeAccess();

Configure the chain compute time period.

[C#] Copy Code

chain.SetTimePeriodType(AgEChTimePeriodType.eUserSpecifiedTimePeriod); 


IAgChUserSpecifiedTimePeriod userSpecifiedTimePeriod = chain.TimePeriod as IAgChUserSpecifiedTimePeriod; 


userSpecifiedTimePeriod.TimeInterval.SetExplicitInterval("1 May 2015 04:00:00.000", "1 May 2015 05:00:00.000");

Prints the strand intervals of chain object

[C#] Copy Code

IAgStkObject chainAsStkObject = chain as IAgStkObject; 


 

// Compute the chain access if not done already. 


chain.ComputeAccess(); 

 

// Considered Start and Stop time

Console.WriteLine("Chain considered stop time: {0}", chainAsStkObject.Vgt.Events["ConsideredStopTime"].FindOccurrence().Epoch); 


 

IAgCrdnEventIntervalCollection objectParticipationIntervals = chainAsStkObject.Vgt.EventIntervalCollections["StrandAccessIntervals"]; 


IAgCrdnIntervalsVectorResult intervalListResult = objectParticipationIntervals.FindIntervalCollection();

{ 

    if (intervalListResult.IsValid) 


    { 

        Console.WriteLine("Link Name: {0}", objectParticipationIntervals.Labels.GetValue(i)); 


        Console.WriteLine("--------------");

            Console.WriteLine("Start: {0}, Stop: {1}", startTime, stopTime);
