[Lemon-devel] Typedef for the base graph in the iterators.

[Alpár Jüttner]

Could you specify these problems? As far as I see, many graph adaptors
(e.g. UndirGraphAdaptor, SplitGraphAdaptor) use inheritance, not
typedef. Do they suffer from these drawbacks?

Btw, we have both UndirGraphAdaptor and UGraphAdaptor, and they do very
different things. It is quite confusing, isn't it?

In order to prevent people from receiving viruses
that would seem to originate from my email,
if you use Microsoft Windows you do not have permission
to add this address to your address book.
If I am in your address book, please remove me.
Of course, this does not apply to GNU/Linux users. 
Thank you.
