approve

public ContactExchange.Item.Action approve(ContactExchange.Item item)

Approves a roster exchange item by modifying the roster accordingly.

If the item is to be added and does not yet exist, it will be added to your roster and you are subscribed to its presence.
If it already exists in your roster but in a different group than suggested, it will additionally be added to the suggested group.

If the item is to be deleted, it will be deleted from your roster, if the suggested group(s) matches the same group(s) in your roster.
Otherwise it will be edited, so that it no longer belongs to the suggested groups.

If the item is to be modified, it will be modified accordingly, if it exists.

Parameters:

item - The roster exchange item.

Returns:

The action, which was actually performed. This may vary from the specified action, e.g. if you add a contact that already exists, only its groups are updated. If no action was performed, e.g. if you want to delete a contact, that does not exist, null is returned.
