        public java.io.InputStream getKeyboard()
        从接口复制的说明: CommandSession
        Return the input stream that is the first of the pipeline. This stream is sometimes necessary to communicate directly to the end user. For example, a "less" or "more" command needs direct input from the keyboard to control the paging.
        指定者:
        getKeyboard 在接口中 CommandSession
        返回:
        InpuStream used closest to the user or null if input is from a file.

      • getConsole

        public java.io.PrintStream getConsole()
        从接口复制的说明: CommandSession
        Return the PrintStream for the console. This must always be the stream "closest" to the user. This stream can be used to post messages that bypass the piping. If the output is piped to a file, then the object returned must be null.
        指定者:
        getConsole 在接口中 CommandSession
        返回:

      • format
