Class SocketConnection

  • All Implemented Interfaces:
    Closeable, AutoCloseable, Connection

    public class SocketConnection
    extends AbstractConnection
    Deprecated.
    Old, pre NIO / MINA code. Should not be used as Netty offers better performance. Currently only in use for server dialback.
    An object to track the state of a XMPP client-server session. Currently, this class contains the socket channel connecting the client and server.

        socket - the socket to represent.
        isEncrypted - true if this is a encrypted connection.
        Throws:
        IOException - if there was a socket error while sending the packet.

      • getTLSStreamHandler

        public TLSStreamHandler getTLSStreamHandler()
        Deprecated.
        Returns the stream handler responsible for encrypting the plain connection and providing the corresponding input and output streams.
        Returns:
        the stream handler responsible for encrypting the plain connection and providing the corresponding input and output streams.
      • startTLS

        public void startTLS​(boolean clientMode,
                             boolean directTLS)
                      throws IOException
        Deprecated.
        Description copied from interface: Connection
        Encrypts the plain connection by negotiating TLS with the other peer. In a server-2-server connection the server requesting the TLS negotiation will be the client and the other server will be the server during the TLS negotiation. Therefore, the server requesting the TLS negotiation must pass true in the clientMode parameter and the server receiving the TLS request must pass false in the clientMode parameter.

        In the case of client-2-server the XMPP server must pass false in the clientMode parameter since it will behave as the server in the TLS negotiation.

        Parameters:
        clientMode - boolean indicating if this entity is a client or a server in the TLS negotiation.
        directTLS - boolean indicating if the negotiation is directTLS (true) or startTLS (false).
        Throws:
        IOException
      • addCompression

        public void addCompression()
        Deprecated.
        Description copied from interface: Connection
        Adds the compression filter to the connection but only filter incoming traffic. Do not filter outgoing traffic since we still need to send an uncompressed stanza to the client indicating that he can start compressing the traffic. After we sent the uncompresses stanza we can start compression outgoing traffic as well.
      • startCompression

        public void startCompression()
        Deprecated.
        Description copied from interface: Connection
        Start compressing outgoing traffic for this connection. Compression will only be available after TLS has been negotiated. This means that a connection can never be using compression before TLS. However, it is possible to use compression without TLS.
      • getConfiguration

        public ConnectionConfiguration getConfiguration()
        Deprecated.
        Description copied from interface: Connection
        Returns a representation of the desired state for this connection. Note that this is different from the current state of the connection. For example, TLS can be required by configuration, but while the connection has yet to be fully initialized, the current state might not be TLS-encrypted.
        Returns:
        The desired configuration for the connection (never null).
      • validate

        public boolean validate()
        Deprecated.
        Description copied from interface: Connection
        Verifies that the connection is still live. Typically, this is done by sending a whitespace character between packets.
        Returns:
        true if the socket remains valid, false otherwise.
      • isInitialized

        public boolean isInitialized()
        Deprecated.
        Description copied from interface: Connection
        Checks if the connection has finished initialization.
        Returns:
        true if connection has finished initialization.
      • getAddress

        public byte[] getAddress()
                          throws UnknownHostException
        Deprecated.
        Description copied from interface: Connection
        Returns the raw IP address of this InetAddress object. The result is in network byte order: the highest order byte of the address is in getAddress()[0].
        Returns:
        the raw IP address of this object.
        Throws:
        UnknownHostException - if IP address of host could not be determined.
      • getHostAddress

        public String getHostAddress()
                              throws UnknownHostException
        Deprecated.
        Description copied from interface: Connection
        Returns the IP address string in textual presentation.
        Returns:
        the raw IP address in a string format.
        Throws:
        UnknownHostException - if IP address of host could not be determined.
      • getHostName

        public String getHostName()
                           throws UnknownHostException
        Deprecated.
        Description copied from interface: Connection
        Gets the host name for this IP address.

        If this InetAddress was created with a host name, this host name will be remembered and returned; otherwise, a reverse name lookup will be performed and the result will be returned based on the system configured name lookup service. If a lookup of the name service is required, call getCanonicalHostName.

        If there is a security manager, its checkConnect method is first called with the hostname and -1 as its arguments to see if the operation is allowed. If the operation is not allowed, it will return the textual representation of the IP address.

        Returns:
        the host name for this IP address, or if the operation is not allowed by the security check, the textual representation of the IP address.
        Throws:
        UnknownHostException - if IP address of host could not be determined.
        See Also:
        InetAddress.getCanonicalHostName(), SecurityManager.checkConnect(java.lang.String, int)
      • getPort

        public int getPort()
        Deprecated.
        Returns the port that the connection uses.
        Returns:
        the port that the connection uses.
      • getWriter

        public Writer getWriter()
        Deprecated.
        Returns the Writer used to send data to the connection. The writer should be used with caution. In the majority of cases, the deliver(Packet) method should be used to send data instead of using the writer directly. You must synchronize on the writer before writing data to it to ensure data consistency:
          Writer writer = connection.getWriter();
         synchronized(writer) {
             // write data....
         }
        Returns:
        the Writer for this connection.
      • isClosed

        public boolean isClosed()
        Deprecated.
        Description copied from interface: Connection
        Returns true if the connection/session is closed.
        Returns:
        true if the connection is closed.
      • isSecure

        @Deprecated
        public boolean isSecure()
        Deprecated.
        Description copied from interface: Connection
        Returns true if this connection is secure.
        Returns:
        true if the connection is secure (e.g. TLS)
      • isEncrypted

        public boolean isEncrypted()
        Deprecated.
        Description copied from interface: Connection
        Returns true if this connection is encrypted.
        Returns:
        true if the connection is encrypted (e.g. uses TLS)
      • isCompressed

        public boolean isCompressed()
        Deprecated.
        Description copied from interface: Connection
        Returns true if the connection is using compression.
        Returns:
        true if the connection is using compression.
      • getTLSProtocolName

        public Optional<String> getTLSProtocolName()
        Deprecated.
        Description copied from interface: Connection
        Returns the TLS protocol name used by the connection of the session, if any.
        Returns:
        a TLS protocol (version) name.
      • getCipherSuiteName

        public Optional<String> getCipherSuiteName()
        Deprecated.
        Description copied from interface: Connection
        Returns the TLS cipher suite name used by the connection of the session, if any.
        Returns:
        cipher suite name.
      • getIdleTimeout

        public long getIdleTimeout()
        Deprecated.
      • setIdleTimeout

        public void setIdleTimeout​(long timeout)
        Deprecated.
        Sets the number of milliseconds a connection has to be idle to be closed. Sending stanzas to the client is not considered as activity. We are only considering the connection active when the client sends some data or hearbeats (i.e. whitespaces) to the server.
        Parameters:
        timeout - the number of milliseconds a connection has to be idle to be closed.
      • getLocalCertificates

        public Certificate[] getLocalCertificates()
        Deprecated.
        Description copied from interface: Connection
        Returns the local underlying X509Certificate chain for the connection.
        Returns:
        an ordered array of certificates, with the local certificate first followed by any certificate authorities. If no certificates is present for the connection, then null is returned.
      • getPeerCertificates

        public Certificate[] getPeerCertificates()
        Deprecated.
        Description copied from interface: Connection
        Returns the underlying X509Certificate for the connection of the peer.
        Returns:
        an ordered array of peer certificates, with the peer's own certificate first followed by any certificate authorities.
      • setUsingSelfSignedCertificate

        public void setUsingSelfSignedCertificate​(boolean isSelfSigned)
        Deprecated.
        Description copied from interface: Connection
        Keeps track if the other peer of this session presented a self-signed certificate. When using self-signed certificate for server-2-server sessions then SASL EXTERNAL will not be used and instead server-dialback will be preferred for vcerifying the identify of the remote server.
        Parameters:
        isSelfSigned - true if the other peer presented a self-signed certificate.
      • isUsingSelfSignedCertificate

        public boolean isUsingSelfSignedCertificate()
        Deprecated.
        Description copied from interface: Connection
        Returns true if the other peer of this session presented a self-signed certificate. When using self-signed certificate for server-2-server sessions then SASL EXTERNAL will not be used and instead server-dialback will be preferred for vcerifying the identify of the remote server.
        Returns:
        true if the other peer of this session presented a self-signed certificate.
      • getPacketDeliverer

        @Nullable
        public PacketDeliverer getPacketDeliverer()
        Deprecated.
        Description copied from interface: Connection
        Returns the packet deliverer to use when delivering a packet over the socket fails. The packet deliverer will retry to send the packet using some other connection or will store the packet offline for later retrieval. When null, packets will just be dropped.
        Returns:
        the packet deliverer to use when delivering a packet over the socket fails.
      • close

        public void close​(@Nullable
                          org.xmpp.packet.StreamError error,
                          boolean networkInterruption)
        Deprecated.
        Description copied from interface: Connection
        Close this connection including associated session, optionally citing a stream error. The 'networkInterruption' argument should be set to 'true' if the connection is being closed because it is known or assumed that the network connection between Openfire and the peer was unexpectedly terminated (eg: due to a networking failure). These typically are scenarios where a peer becomes unresponsive (without having terminated its session with a or comparable message). When the 'networkInterruption' argument is set to 'true', then a session is eligible for resumption (if Stream Management was activiated for the session). The events for closing the connection are:
        • Set closing flag to prevent redundant shutdowns.
        • Close the socket.
        • Notify all listeners that the channel is shut down.
        Not all implementations use the same order of events.
        Parameters:
        error - If non-null, the end-stream tag will be preceded with this error.
      • systemShutdown

        public void systemShutdown()
        Deprecated.
        Description copied from interface: Connection
        Notification message indicating that the server is being shutdown. Implementors should send a stream error whose condition is system-shutdown before closing the connection.
      • deliver

        public void deliver​(org.xmpp.packet.Packet packet)
                     throws UnauthorizedException,
                            PacketException
        Deprecated.
        Description copied from interface: Connection
        Delivers the packet to this connection without checking the recipient. The method essentially calls socket.send(packet.getWriteBuffer()). Use with caution! This code is unlikely to be called directly. Instead, ensure that data sent to the entities is sent through the appropriate LocalSession object. For clients, this prevents, for example, synchronisation issues with stanza counts related to Stream Management (XEP-0198).
        Parameters:
        packet - the packet to deliver.
        Throws:
        UnauthorizedException - if a permission error was detected.
        PacketException
      • deliverRawText

        public void deliverRawText​(String text)
        Deprecated.
        Description copied from interface: Connection
        Delivers raw text to this connection. This is a very low level way for sending XML stanzas to the client. This method should not be used unless you have very good reasons for not using Connection.deliver(org.xmpp.packet.Packet).

        This method avoids having to get the writer of this connection and mess directly with the writer. Therefore, this method ensures a correct delivery of the stanza even if other threads were sending data concurrently.

        Parameters:
        text - the XML stanzas represented kept in a String.
      • setSocketReader

        public void setSocketReader​(SocketReader socketReader)
        Deprecated.
