[Cuis-dev] Stream hierarchy

[Weslleymberg Lisboa]

Hi,

One thing that bugs me a lot is how the Stream hierarchy is defined. Why is ReadWriteStream a subclass of WriteStream where all the methods for reading have to be reimplemented and duplicated from ReadStream?

I've read the corresponding chapter in the Blue Book but it just describes the classes, doesn't explain why it's done this way.

The way I see it, it makes more sense that ReadStream and WriteStream be more specialized Streams which subclass ReadWriteStream and overrides the unneeded methods to raise SholdNotImplement. Like this:

Stream
    PositionableStream
        ReadWriteStream
            ReadStream
            WriteStream

What am I missing?

I'm not proposing a change or anything like that. It's just that the curiosity to understand this is killing me :)
