| michael@0 | 28 | * The nsDBusService component interfaces with DBUS to communicate with daemons |
| michael@0 | 29 | * in systems supporting DBUS. It links dynamically to the DBUS libraries so |
| michael@0 | 30 | * will not load on systems without those libraries ... but that's harmless. |
| michael@0 | 31 | * |
| michael@0 | 32 | * Currently the only daemon we communicate with is NetworkManager. We listen |
| michael@0 | 33 | * for NetworkManager state changes; we set nsIOService's offline status to |
| michael@0 | 34 | * FALSE when NetworkManager reports NM_STATE_CONNECTED, and to TRUE otherwise. |
| michael@0 | 35 | * We also solicit the current status from NetworkManager when this component |
| michael@0 | 36 | * gets loaded. |
| michael@0 | 37 | * |
| michael@0 | 38 | * In the future we could extend this class to talk to other daemons. |
| michael@0 | 39 | * |
| michael@0 | 40 | * Currently all communication is asynchronous. This isn't hard to implement |
| michael@0 | 41 | * and avoids blocking our main thread. |
