Re: [Boost-users] Container with insertion order

Another (last ?) question: how is possible simulate operator== for boost multi_index?

No need to simulate, comparison operators are already defined for MIC. You should only provide the relevant ops for your elements. In case of mutable_pair it would look like this: template bool operator ==(const mutable_pair &lhs, const mutable_pair &rhs) { return lhs.first == rhs.first && lhs.second == rhs.second; }
