Class SocketReader

  • All Implemented Interfaces:
    Runnable

    public abstract class SocketReader
    extends Object
    implements Runnable
    Deprecated.
    Old, pre NIO / MINA code. Should not be used as Netty offers better performance. Currently only in use for server dialback.
    A SocketReader creates the appropriate Session based on the defined namespace in the stream element and will then keep reading and routing the received packets.

      • SocketReader

        public SocketReader​(PacketRouter router,
                            RoutingTable routingTable,
                            String serverName,
                            Socket socket,
                            SocketConnection connection,
                            boolean useBlockingMode,
                            boolean directTLS)
        Deprecated.
        Creates a dedicated reader for a socket.
        Parameters:
        router - the router for sending packets that were read.
        routingTable - the table that keeps routes to registered services.
        serverName - the name of the server this socket is working for.
        socket - the socket to read from.
        connection - the connection being read.
        useBlockingMode - true means that the server will use a thread per connection.
        directTLS - false means that the socket initially is a plaintext connection.
    • Method Detail

      • run

        public void run()
        Deprecated.
        A dedicated thread loop for reading the stream and sending incoming packets to the appropriate router.
        Specified by:
        run in interface Runnable
      • process

        protected void process​(org.dom4j.Element doc)
                        throws Exception
        Deprecated.
        Throws:
        Exception
      • processIQ

        protected void processIQ​(org.xmpp.packet.IQ packet)
                          throws UnauthorizedException
        Deprecated.
        Process the received IQ packet. Registered PacketInterceptor will be invoked before and after the packet was routed.

        Subclasses may redefine this method for different reasons such as modifying the sender of the packet to avoid spoofing, rejecting the packet or even process the packet in another thread.

        Parameters:
        packet - the received packet.
        Throws:
        UnauthorizedException - if the connection required encryption but was not encrypted.
      • processPresence

        protected void processPresence​(org.xmpp.packet.Presence packet)
                                throws UnauthorizedException
        Deprecated.
        Process the received Presence packet. Registered PacketInterceptor will be invoked before and after the packet was routed.

        Subclasses may redefine this method for different reasons such as modifying the sender of the packet to avoid spoofing, rejecting the packet or even process the packet in another thread.

        Parameters:
        packet - the received packet.
        Throws:
        UnauthorizedException - if the connection required encryption but was not encrypted.
      • processMessage

        protected void processMessage​(org.xmpp.packet.Message packet)
                               throws UnauthorizedException
        Deprecated.
        Process the received Message packet. Registered PacketInterceptor will be invoked before and after the packet was routed.

        Subclasses may redefine this method for different reasons such as modifying the sender of the packet to avoid spoofing, rejecting the packet or even process the packet in another thread.

        Parameters:
        packet - the received packet.
        Throws:
        UnauthorizedException - if the connection required encryption but was not encryption.
      • createSession

        protected void createSession()
                              throws UnauthorizedException,
                                     org.xmlpull.v1.XmlPullParserException,
                                     IOException
        Deprecated.
        Uses the XPP to grab the opening stream tag and create an active session object. The session to create will depend on the sent namespace. In all cases, the method obtains the opening stream tag, checks for errors, and either creates a session or returns an error and kills the connection. If the connection remains open, the XPP will be set to be ready for the first packet. A call to next() should result in an START_TAG state with the first packet in the stream.
        Throws:
        UnauthorizedException - if the connection required encryption but was not encrypted.
        org.xmlpull.v1.XmlPullParserException - if there was an XML error while creating the session.
        IOException - if an IO error occurred while creating the session.
      • shutdown

        protected void shutdown()
        Deprecated.
        Notification message indicating that the SocketReader is shutting down. The thread will stop reading and processing new requests. Subclasses may want to redefine this message for releasing any resource they might need.
