      java.io.IOException - if an I/O problem occurs

    • readRawLine

      public static byte[] readRawLine​(java.io.InputStream inputStream) throws java.io.IOException
      Return byte array from an (unchunked) input stream. Stop reading when "\n" terminator encountered If the stream ends before the line terminator is found, the last part of the string will still be returned. If no input data available, null is returned.
      Parameters:
      inputStream - the stream to read from
