Description
Updates the collection to reflect changes to its items.
Override Update in a descendent class to make any necessary changes when the items in the collection change. This method is called automatically when an update is complete.
Item
identifies the item that changed. If the Item
parameter is nil (Delphi) or NULL (C++), then the change affects more than one item in the collection.
As implemented in TCollection, Update does nothing. Descendent classes override this method to make any necessary adjustments.
