| 27 /** | |
| 28 * The nsDBusService component interfaces with DBUS to communicate with daemons | |
| 29 * in systems supporting DBUS. It links dynamically to the DBUS libraries so | |
| 30 * will not load on systems without those libraries ... but that's harmless. | |
| 31 * | |
| 32 * Currently the only daemon we communicate with is NetworkManager. We listen | |
| 33 * for NetworkManager state changes; we set nsIOService's offline status to | |
| 34 * FALSE when NetworkManager reports NM_STATE_CONNECTED, and to TRUE otherwise. | |
| 35 * We also solicit the current status from NetworkManager when this component | |
| 36 * gets loaded. | |
| 37 * | |
| 38 * In the future we could extend this class to talk to other daemons. | |
| 39 * | |
| 40 * Currently all communication is asynchronous. This isn't hard to implement | |
| 41 * and avoids blocking our main thread. | |
