Anyone using the brl.data module?

I've been looking at various ways to read/write my objects directly from/to a TStream. Whilst digging in the Blitz Max source I found TData and TDataType. On the surface these do exactly what I'm looking for, but they are totally undocumented as far as I can tell. My question is, is anyone using these types and do they indeed do what I think they do? Are they safe to use, or were they intended for internal use only?

Bruceys persistence mod can do this via reflection.
Did you test it?

I prefer to handle that by serialize and deserialize methods for a type.

I used them once to implement some custom data structure in a stream friendly way. Check out BRL.LinkedList to see how they are used.

Does this help?

Thanks for all the replies. It turns out the solution to my problem was amazingly simple. I'm only reading/writing pixmaps to streams, and it seems LoadPixmap and SavePixmap can be given any TStream at any position.

@Volkar: Hadn't seen that module before. It's a bit overkill for what I'm doing at the moment, but I have a back burner project that it seems perfectly suited for. So thanks for bringing it to my attention.

@tonyg: That's about as far as I had got by looking at the source, but TPixmapDataType.ReadObject didn't return anything so it was confusing me.
