[Boost-users] BGL adaption question

Hello,

I adapt my own graph like data structures. They form a derivation hierarchy,
and they are all in the same graph category.

In order to avoid that I have to repeat the specializations of the
graph traits, I put all the types needed in the base class, so
the default graph traits, which just takes the types out of the class
it is applied to, will get them from the base class or via inherited
types from the base class.

What can I do in order to repeat the definition of the functions
source(..), target(..) etc.

I could tell my users to downcast but that's not nice.  I also
could have #defines for all my classes so that I write the code
only once, but all these solutions are not appealing.

any suggestion?
