Description

Access or create VGT systems associated with an object or a central body.

Public Methods

Contains	Searches for a an element with a given name. Returns false if the specified element does not exist.
GetItemByIndex	Retrieves a system from the collection by index.
GetItemByName	Retrieves a system from the collection by name.
Remove	Removes a specified System.

Public Properties

CommonTasks	Provides access to common tasks that allow users quickly carry out tasks such as creating known systems, etc.
Context	Returns a context object. The context can be used to find out which central body or STK object this instance is associated with.
Count	Returns a number of elements in the collection.
Factory	Returns a Factory object used to create custom VGT systems.
Item	Returns a System by name or at a specified position.

Example

Enumerate the existing systems.

[C#]

// Enumerate the existing Systems using specified CrdnProvider.
foreach (IAgCrdnSystem system in provider.Systems)
{
    // All systems implement IAgCrdn interface which provides
    // information about the system instance and its type.
    IAgCrdn crdn = system as IAgCrdn;
    Console.WriteLine("Name: {0}, type: {1}", crdn.Name, system.Type);
}

Iterate through existing systems (coordinate reference frames).

[C#]

// Iterate through the the group of existing systems associated
// with the specified CrdnProvider.
for (int i = 0; i < provider.Systems.Count; i++)
{
    IAgCrdnSystem crdnSystem = provider.Systems[i];
    // All coordinate reference frames implement IAgCrdn interface which provides
    // information about the reference frame's instance and its type.
    IAgCrdn crdn = provider.Systems[i] as IAgCrdn;
    // Print the reference frame's name and type to the standard output.
    Console.WriteLine("Name: {0}, type: {1}", crdn.Name, crdnSystem.Type);
}

Enumerate the existing systems.

[Visual Basic .NET]

' Enumerate the existing Systems using specified CrdnProvider.
For Each system As IAgCrdnSystem In provider.Systems
	' All systems implement IAgCrdn interface which provides
	' information about the system instance and its type.
	Dim crdn As IAgCrdn = TryCast(system, IAgCrdn)
	Console.WriteLine("Name: {0}, type: {1}", crdn.Name, system.Type)

Iterate through existing systems (coordinate reference frames).

[Visual Basic .NET]

' Iterate through the the group of existing systems associated
' with the specified CrdnProvider.
Dim i As Integer = 0
While i < provider.Systems.Count
	Dim crdnSystem As IAgCrdnSystem = provider.Systems(i)
	' All coordinate reference frames implement IAgCrdn interface which provides
	' information about the reference frame's instance and its type.
	Dim crdn As IAgCrdn = TryCast(provider.Systems(i), IAgCrdn)
	' Print the reference frame's name and type to the standard output.
	Console.WriteLine("Name: {0}, type: {1}", crdn.Name, crdnSystem.Type)
	System.Math.Max(System.Threading.Interlocked.Increment(i),i - 1)
End While
