John,

One quick question instead of having individual getters like
this xxxx, xxxy etc. would it be ok to have one generic getter
that takes a constant as a parameter
e.g:
<somename>(int attribute) and we define constants XXXX, XXXY etc.
so uses would do <somename>(XXXX) instead of xxxx.

Would that be very unreadable in the code?
