    - #### getBytesRead

          public long getBytesRead()

      Returns the number of bytes, which have been read by the stream.
      Returns:
        Number of bytes, which have been read so far.

    - #### available

          public int available()
                        throws IOException

      Returns the number of bytes, which are currently available, without blocking.
      Overrides:
        `available` in class `InputStream`
      Returns:
        Number of bytes in the buffer.
      Throws:
        `IOException` - An I/O error occurs.

    - #### read

          public int read()
                   throws IOException

      Returns the next byte in the stream.
      Specified by:
        `read` in class `InputStream`
      Returns:
        The next byte in the stream, as a non-negative integer, or -1 for EOF.
      Throws:
        `IOException` - An I/O error occurred.

    - #### read

          public int read(byte[] b,
                 int off,

                   throws IOException

      Reads bytes into the given buffer.
      Overrides:
        `read` in class `InputStream`
      Parameters:
        `b` - The destination buffer, where to write to.
        `off` - Offset of the first byte in the buffer.
        `len` - Maximum number of bytes to read.
      Returns:
        Number of bytes, which have been actually read, or -1 for EOF.
      Throws:
        `IOException` - An I/O error occurred.
