[Boost-users] implementing an iterator

I'm using iterator_facade to implement an iterator over file based data.

So, my question is, since deference returns a reference to a value does 
that reference need to persist when the iterator is incremented or 
decremented?

Because this is file based data I can't always keep a reference around 
because the data is stored on disk.

Thanks,

Chris
