Synchronizing different classes on the same mutex in C++
Francesco Balestrieri
I have a number of C++ classes, and I would like all their instances to
synchronize on the same mutex. The reason is that the classes contain linked
lists to objects of the other classes, and need to navigate several objects'
data.
So far I came up with these possibilities:
- have an interface class that accesses the objects in mutual exclusion, and
have all navigations done via this class. Problem: I have to rewrite a lot
of additional methods.
- have a global mutex and pass it to the objects in the constructor.
Problem: it's not transparent to the user.
I have the feeling that there is a better, more OO way to do it, but can't
figure it out myself. Can anybody suggest something, or at least give a
reference I could check? I guess you can tell from the way I put the
question that I'm new to this sort of things, so I apologise already if this
is a dumb question.
Thanks in advance,
Francesco
