When the item is required the hard and soft references are examined to detect an existing item in memory . If there is one then this item is used . If the item does not have a hard or soft reference but does have a persistent representation then we attempt to restore the item from its persistent representation . If we have no persistent representation or fail to recreate from the persistent representation then we unlink the link .
