1.31 + * The nsDBusService component interfaces with DBUS to communicate with daemons
1.32 + * in systems supporting DBUS. It links dynamically to the DBUS libraries so
1.33 + * will not load on systems without those libraries ... but that's harmless.
1.34 + *
1.35 + * Currently the only daemon we communicate with is NetworkManager. We listen
1.36 + * for NetworkManager state changes; we set nsIOService's offline status to
1.37 + * FALSE when NetworkManager reports NM_STATE_CONNECTED, and to TRUE otherwise.
1.38 + * We also solicit the current status from NetworkManager when this component
1.39 + * gets loaded.
1.40 + *
1.41 + * In the future we could extend this class to talk to other daemons.
1.42 + *
1.43 + * Currently all communication is asynchronous. This isn't hard to implement
1.44 + * and avoids blocking our main thread.
