Describes the action that causes a change to a collection.
public enum class CollectionChange
There is only one notification per type of change to a collection. For example, if an item is inserted, then only a notification for an insertion is sent to a listener that is subscribed to receive change notifications. Use the Index property of the IVectorChangedEventArgs interface or the Key property of the IMapChangedEventArgs<K> interface to determine the location of the change.
