Description

Defines an event (time instant).

Public Methods

FindOccurrence	Return computed time instance if it occurs.
OccursBefore	Return true if computed time instance occurs before or at specified time, return false otherwise.

Public Properties

NoonToday	Return time instant that corresponds to today's GMT noon.
NoonTomorrow	Return time instant that corresponds to tomorrow's GMT noon.
Today	Return time instant that corresponds to today's GMT midnight.
Tomorrow	Return time instant that corresponds to tomorrow's GMT midnight.
Type	Return the type of time instant.

Example

Determine if event occurs before an epoch.

[C#]

// The event you are interested in.
IAgCrdnEvent timeEvent1 = provider.Events["GroundTrajectory.Detic.LLA.Altitude.TimeOfMax"];

// The reference event you want to determine if event of interest happened before.
IAgCrdnEvent timeEvent2 = provider.Events["GroundTrajectory.Detic.LLA.Altitude.TimeOfMin"];
IAgCrdnEventFindOccurrenceResult occurrence2 = timeEvent2.FindOccurrence();

if (occurrence2.IsValid)
{
    if (timeEvent1.OccursBefore(occurrence2.Epoch))
    {
        Console.WriteLine("The time of maximum altitude happend before time of minimum altitude");
    }
    else
    {
        Console.WriteLine("The time of minimum altitude happend before time of maximum altitude");
    }
}

Determine the time of an event.

[C#]

IAgCrdnEvent timeEvent = provider.Events["PassIntervals.First.Start"];

IAgCrdnEventFindOccurrenceResult occurrence = timeEvent.FindOccurrence();

if (occurrence.IsValid)
{
    Console.WriteLine("The first pass interval happened at: " + occurrence.Epoch);
}
else
{
    Console.WriteLine("The first pass interval never occurred");
}

Determine if event occurs before an epoch.

[Visual Basic .NET]

' The event you are interested in.
Dim timeEvent1 As IAgCrdnEvent = provider.Events("GroundTrajectory.Detic.LLA.Altitude.TimeOfMax")

' The reference event you want to determine if event of interest happened before.
Dim timeEvent2 As IAgCrdnEvent = provider.Events("GroundTrajectory.Detic.LLA.Altitude.TimeOfMin")
Dim occurrence2 As IAgCrdnEventFindOccurrenceResult = timeEvent2.FindOccurrence()

If occurrence2.IsValid Then
	If timeEvent1.OccursBefore(occurrence2.Epoch) Then
		Console.WriteLine("The time of maximum altitude happend before time of minimum altitude")
	Else
		Console.WriteLine("The time of minimum altitude happend before time of maximum altitude")
	End If
End If

Determine the time of an event.

[Visual Basic .NET]

Dim timeEvent As IAgCrdnEvent = provider.Events("PassIntervals.First.Start")

Dim occurrence As IAgCrdnEventFindOccurrenceResult = timeEvent.FindOccurrence()

If occurrence.IsValid Then
	Console.WriteLine("The first pass interval happened at: " + occurrence.Epoch)
Else
	Console.WriteLine("The first pass interval never occurred")
End If
