Re: Field Header

I have a Stream class, which handles in short the manipulation of vector
of chars, and what I need also is something that creates a header.

Now I only have (now) two possibilities
- type + payload
- type + size + payload

And that's what I'm using:

class FieldHeader : public Stream
{
public:
     stream_t type;
     stream_t size;
     static const size_t TYPE = sizeof(stream_t);
     static const size_t SIZE = sizeof(stream_t);
     static const size_t TYPE_SIZE = TYPE + SIZE;

     FieldHeader(stream_t);
     FieldHeader(stream_t, stream_t);
     FieldHeader(const Stream&, bool full=true);

     static Stream createField(const Serializable&, stream_t, bool full=true);
};

it works and with "createField" I create the whole stream containing
payload and header, BUT

- the TYPE, SIZE, TYPE_SIZE are quite ugly
   I would like to use "sizeof(type)" for example if possible, but a
   static variable can't use a non-static variable (of course).

- if I want to add other fields is quite painful

Any suggestions to make this better?
