60 * Helper class to handle multiple async queries at the same time inside TrackerChangeListener. |
|
61 * This class is designed to be generic, and initially used to get all contacts that correspond |
|
62 * to list of IMAccounts. When we get signal that multiple IMAccounts have changed, we read |
|
63 * all contacts and emit signal contacts changed for them. |
|
64 * |
|
65 * Usage: construct AsyncQuery with RDFSelect query. When signal queryReady(AsyncQuery *self) |
|
66 * is received, read data from rows in self->nodes (self-nodes()->rowCount() ...) |
|
67 * |
|
68 * Intention: The class has been created to wrap LiveNodes::modelUpdated signal, |
|
69 * and to know which query it corresponds to (not possible to fetch it from sender()). |
|
70 * \sa queryReady(AsyncQuery *) |
