Interface IoHandler

    • Method Detail

      • sessionCreated

        void sessionCreated​(IoSession session)
                     throws java.lang.Exception
        Invoked from an I/O processor thread when a new connection has been created. Because this method is supposed to be called from the same thread that handles I/O of multiple sessions, please implement this method to perform tasks that consumes minimal amount of time such as socket parameter and user-defined session attribute initialization.
        Throws:
        java.lang.Exception
      • sessionOpened

        void sessionOpened​(IoSession session)
                    throws java.lang.Exception
        Invoked when a connection has been opened. This method is invoked after sessionCreated(IoSession). The biggest difference from sessionCreated(IoSession) is that it's invoked from other thread than an I/O processor thread once thread modesl is configured properly.
        Throws:
        java.lang.Exception
      • sessionClosed

        void sessionClosed​(IoSession session)
                    throws java.lang.Exception
        Invoked when a connection is closed.
        Throws:
        java.lang.Exception
      • sessionIdle

        void sessionIdle​(IoSession session,
                         IdleStatus status)
                  throws java.lang.Exception
        Invoked with the related IdleStatus when a connection becomes idle. This method is not invoked if the transport type is UDP; it's a known bug, and will be fixed in 2.0.
        Throws:
        java.lang.Exception
      • exceptionCaught

        void exceptionCaught​(IoSession session,
                             java.lang.Throwable cause)
                      throws java.lang.Exception
        Invoked when any exception is thrown by user IoHandler implementation or by MINA. If cause is instanceof IOException, MINA will close the connection automatically.
        Throws:
        java.lang.Exception
      • messageReceived
