    • Method Detail

      • position

        public int position()
      • limit

        public int limit()
      • capacity

        public int capacity()
      • read

        public int read()
        Reads the next byte of data from buf. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the buffer has been reached, the value -1 is returned.
        Returns:
        the next byte of data, or -1 if the end of the stream has been reached.
