Index is the current index of the item in its managing collection's TCollection.Items property. This property may change as items are added and removed from the collection.

The index of an item is zero-based, i.e. the first item has index zero. The last item has index Count-1 where Count is the number of items in the collection.

The Index property of the items in a collection form a continuous series ranging from 0 to Count-1. The TCollectionItem.ID property does not form a continuous series, but can also be used to identify an item.
