Detailed Description

A wrapper for a binary input stream that supports aligned read operations.

The implementation does not support seeking back the wrapped stream. All seeking operations (tell, seekTo, align) are performed relative to the position of the wrapped stream at construction time of this wrapper. It is possible to construct this wrapper with an unseekable input stream without losing any functionality.
