Class StpConnection

java.lang.Object
  com.opera.core.systems.scope.stp.StpConnection

All Implemented Interfaces:

SocketListener

public class StpConnection
extends Object
implements SocketListener

Nested Class Summary

static class

StpConnection.State

Constructor Summary

StpConnection(SocketChannel socket, IConnectionHandler handler, EventHandler eventHandler, SocketMonitor monitor)
Initializes variables in object scope, sets 'count known' to false to read byte count (STP/0).

Method Summary

boolean	canRead(SelectableChannel channel)
boolean	canWrite(SelectableChannel channel)
void	close() Switches the wait state and wakes up the selector to process.
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.
void	sendEnableStp1()
void	sendQuit()
