Occurred Method (IAgCrdnEventIntervalList)
See Also  Example
Epoch
Specify an epoch. The method may throw an exception if the epoch parameter specified cannot be converted to a currently selected date unit.





Description

Determine if speified time falls within computed interval list.

Syntax

[Visual Basic .NET] 
Public Function Occurred( _
   ByVal Epoch As System.Object _
) As Boolean
[C#] 
public bool Occurred(

   System.Object Epoch

);
[Managed C++] 
public: bool Occurred(

   VARIANT Epoch

);
[Java] 
public bool occurred(

   Variant Epoch

);
[Unmanaged C++] 
public: HRESULT Occurred(

   VARIANT Epoch, 

   VARIANT_BOOL * ReturnValue

);

Parameters

Epoch
Specify an epoch. The method may throw an exception if the epoch parameter specified cannot be converted to a currently selected date unit.

Example

Determine if epoch occured in interval collection.
[C#] Copy Code
IAgCrdnEventIntervalList intervalList = provider.EventIntervalLists["AttitudeIntervals"]; 
 
// The reference event you want to determine if event of interest happened before. 
IAgCrdnEvent timeEvent = provider.Events["GroundTrajectory.Detic.LLA.Altitude.TimeOfMin"]; 
IAgCrdnEventFindOccurrenceResult occurrence = timeEvent.FindOccurrence(); 
 
if (intervalList.Occurred(occurrence.Epoch)) 
{ 
    Console.WriteLine("The time of maximum altitude occurred in event interval list."); 
} 
else 
{ 
    Console.WriteLine("The time of maximum altitude did not occurred in event interval list."); 
} 
 
Determine if epoch occured in interval collection.
[Visual Basic .NET] Copy Code
Dim intervalList As IAgCrdnEventIntervalList = provider.EventIntervalLists("AttitudeIntervals")

' The reference event you want to determine if event of interest happened before.
Dim timeEvent As IAgCrdnEvent = provider.Events("GroundTrajectory.Detic.LLA.Altitude.TimeOfMin")
Dim occurrence As IAgCrdnEventFindOccurrenceResult = timeEvent.FindOccurrence()

If intervalList.Occurred(occurrence.Epoch) Then
    Console.WriteLine("The time of maximum altitude occurred in event interval list.")
Else
    Console.WriteLine("The time of maximum altitude did not occurred in event interval list.")
End If
