Hello
I want a collection to store a relationship N to M like so:
Item of type A Item of type B
A1 B1,B2,B3
A2 B4
A3 B1
and I would like a convenient way to get from a A instance to the list of B
instances, and vice versa, from a given B instance to the list of A
instances.
At runtime, the A objects are created first, then a list of B objects is
created.
Later, B objects get modified asynchronously and that modification need to
update the relevant A instances
what container to use?
boost::bimap< unordered_set<A*> , unordered_set<B*> >
?
