boolean	isConnected()
void	parseServiceList(String message) Processes an incoming message and passes it to event handler if needed, the following events are to our interest: Runtime-Started: ecmascript runtime starts in Opera (that we can inject to) Runtime-Stopped: ecmascript runtime stops (not used, buggy) Message: fired from console log event Updated-Window: a window is updated OR created (opener-id=0) Active-Window: window focus changed Window-Closed: self explanatory If message matches none it is added to the response queue (probably response to command).
void	send(UmsProtos.Command command) Queues up an STP/1 message sent from another thread and wakes up selector to register it to the key.
