    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.

  - ### close

    public void close() throws IOException
    Closes the input stream.
    Specified by:
      `close` in interface `AutoCloseable`

      `close` in class `InputStream`
    Throws:
      `IOException` - An I/O error occurred.

  - ### close

    public void close(boolean closeUnderlying) throws IOException
    Closes the input stream.
    Parameters:
      `closeUnderlying` - Whether to close the underlying stream (hard close)
    Throws:
      `IOException` - An I/O error occurred.

  - ### 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.

  - ### isClosed

    public boolean isClosed()
    Returns, whether the stream is closed.
    Specified by:
      `isClosed` in interface `Closeable`
    Returns:
      True, if the stream is closed, otherwise false.

  - ### 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, int len) 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.
