    • Method Detail

      • setTimeout

        void setTimeout​(int timeout)
         throws java.io.IOException
        Enable/disable TIMEOUT with the specified timeout, in milliseconds. With this option set to a non-zero timeout, a read() call on the InputStreamm associated with this StreamAcessor will block for only this amount of time. If the timeout expires, a java.net.SocketTimeoutException is raised, though the Socket is still valid. The option must be enabled prior to entering the blocking operation to have effect. The timeout must be > 0. A timeout of zero is interpreted as an infinite timeout.
        Parameters:
        timeout - the specified timeout, in milliseconds.
        Throws:
        java.io.IOException - if there is an error in the underlying protocol, such as a TCP error.

      • getInputStream

        java.io.DataInputStream getInputStream()
                                throws java.io.IOException
        Returns the input stream for this stream accessor.
        Returns:
        the input stream.
        Throws:
        java.io.IOException - an I/O error accessing the input stream, the stream accessor is closed, the stream accessor is not connected.

      • getOutpuStream

        java.io.DataOutputStream getOutpuStream()
                                 throws java.io.IOException
        Returns the output stream for this stream accessor.
        Returns:
        the output stream.
        Throws:
        java.io.IOException - an I/O error accessing the output stream, the stream accessor is closed, the stream accessor is not connected.
