   Bases: :py:obj:`dissect.util.stream.AlignedStream`


   Basic buffered stream that provides aligned reads.

   Must be subclassed for various stream implementations. Subclasses can implement:
       - :meth:`~AlignedStream._read`
       - :meth:`~AlignedStream._seek`

   The offset and length for ``_read`` are guaranteed to be aligned for streams of a known size.
   If your stream has an unknown size (i.e. ``size == None``), reads of length ``-1`` (i.e. read until EOF) will be
   passed through to your implementation of ``_read``.
   The only time that overriding ``_seek`` would make sense is if there's no known size of your stream,
   but still want to provide ``SEEK_END`` functionality.

   Most subclasses of ``AlignedStream`` take one or more file-like objects as source.
   Operations on these subclasses, like reading, will modify the source file-like object as a side effect.

   :param size: The size of the stream. This is used in read and seek operations. ``None`` if unknown.
   :param align: The alignment size. Read operations are aligned on this boundary. Also determines buffer size.
