- (void)xmppRoster:(XMPPRosterMemoryStorage *)sender didAddUser:(XMPPUserMemoryStorageObject *)user

- (void)xmppRoster:(XMPPRosterMemoryStorage *)sender didUpdateUser:(XMPPUserMemoryStorageObject *)user

- (void)xmppRoster:(XMPPRosterMemoryStorage *)sender didRemoveUser:(XMPPUserMemoryStorageObject *)user

- (void)xmppRoster:(XMPPRosterMemoryStorage *)sender
    didAddResource:(XMPPResourceMemoryStorageObject *)resource
          withUser:(XMPPUserMemoryStorageObject *)user

- (void)xmppRoster:(XMPPRosterMemoryStorage *)sender
 didUpdateResource:(XMPPResourceMemoryStorageObject *)resource
          withUser:(XMPPUserMemoryStorageObject *)user

- (void)xmppRoster:(XMPPRosterMemoryStorage *)sender
