29 * CRsfwMountConnectionStateMachine |
|
30 * |
|
31 * If connect to server fails, deletes the remote accessor |
|
32 * (this comes from the way synch version fo CRsfwFileEngine::ConnectL() used to |
|
33 * to work, but I'm not quite sure how correct behaviour this is). |
|
34 * Note that EnteredConnectionState() in CompleteL |
|
35 * may start reintegration. |
|
36 * However instead of writing special reintegration states here |
|
37 * it is better to later implement a reintegration thred. |
