RE: OO and CSP

["Campbell, John" <John.Campbell@xxxxxxxxxxxxxx>]

Hi Marcel
I'm trying to understand what concurrent objects
might reasonably mean.  I am not a "true believer" in
OO, so if I misconstrue the dogma, please forgive me.

OO seems to address the semantic relationship
of interfacing entities.  CSP addresses concurrency
behavior.  To my way of thinking, these are orthoganal
concepts. But, if not, please enlighten me. Thats
why I posted in the first place.

Whoa! I'm not suggesting a direction to go in. I'm
trying to understand the meaning of a concept.  But
if you have specific objections, that would in fact
help me to understand the concept.
