    • Method Detail

      • isDetached

        public boolean isDetached()
        Returns true if the session is detached (that is, if the underlying connection has been closed while the session instance itself has not been closed).
        Returns:
        true if session detached

      • process

        public void process​(org.xmpp.packet.Packet packet)
        Description copied from interface: ChannelHandler

        Specified by:
        process in interface ChannelHandler<org.xmpp.packet.Packet>

      • deliverRawText

        public void deliverRawText​(String text)
        Description copied from interface: Session
        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 Session.process(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.

        Specified by:
        deliverRawText in interface Session
        Parameters:
        text - the XML stanzas represented kept in a String.

      • getAvailableStreamFeatures

        public abstract String getAvailableStreamFeatures()
        Returns a text with the available stream features. Each subclass may return different values depending whether the session has been authenticated or not.
        Returns:
        a text with the available stream features or null to add nothing.

      • close

        public void close()
        Description copied from interface: Session
        Close this session including associated socket connection. The order of events for closing the session is:
        • Set closing flag to prevent redundant shutdowns.
        • Call notifyEvent all listeners that the channel is shutting down.
        • Close the socket.
        Specified by:
        close in interface Session

      • validate

        public boolean validate()
        Description copied from interface: Session
        Verifies that the connection is still live. Typically this is done by sending a whitespace character between packets. // TODO No one is sending this message now. Delete it?
        Specified by:
        validate in interface Session
        Returns:
        true if the socket remains valid, false otherwise.

      • isSecure

        public boolean isSecure()
        Description copied from interface: Session
        Returns true if this connection is secure.

        Returns:
        true if the connection is closed.

      • getHostName

        public String getHostName()
                   throws UnknownHostException
        Description copied from interface: Session
        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.

        Specified by:
        getHostName in interface Session
        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)

      • isUsingSelfSignedCertificate

        public boolean isUsingSelfSignedCertificate()

        Returns:
        true if the other peer of this session presented a self-signed certificate.
