[Boost-users] [multi_index] How to use a class instead of a struct with the boost:multi_index_container?

Dear All, I want to use a class instead of a struct to create a multi_index container. But the example that comes with the documention (basic.cpp) uses a struct. Which changes (if there are any) must I make in order to use this container with a class of objects, instead of with structs? Thanks in advance. Best Regards, José Augusto Jr. (jamaj)
