Stefano Bagnara updated MIME4J-50:
----------------------------------

    Attachment: MIME4J-50.patch

Forgot to say that this change allowed me to remove BasicBufferingInputStream 
by moving few methods to InputBuffer and passing around InputBuffer instead of 
BasicBufferingInputStream.

> I create this issue to attach a patch (not sure our mailing list support 
> this).
> I was looking at InputBuffer and I noticed how much it looks like a 
> FilterInputStream class but it doesn't expose the InputStream "interface" 
> (ok, it is not an interface, but an abstract class).
> Am I missing something or extending InputStreamFilter does not add complexity 
> to the class while increasing its flexibility/reusability?
> I gave this a go by making BufferingInputStream an extension of 
> FilterInputStream and by letting InputBuffer extending the "new" 
> BufferingInputStream.
> This also gave me the opportunity to simplify some code aroud avoiding 
> multiple wrapping of the InputBuffer.
> After this patch all of the tests still pass.
> I did not rename "InputBuffer" with this patch, but maybe it should include 
> Buffered, InputStream and Filter words to better autodocumentation.
