Hi, in Example 1 there is a structure: struct employee { int id; std::string name; int age; … }; Is it possible to create automatically A) container with id as an index B) a view with name as index C) a view with age as index ? For this example it is easy to create the containers and views by hand but I plan to use at least 10 structures with many dimensions. For some containers I also need hash_indices - so there is really a lot of similar code, which I don’t want to have. Also I want to provide iterators or one general (template) iterator for all dimensions. How would you write such a general iterator? There should be a function that takes for example “employee_name” or “employee_id” as a parameter to query the employee container. It would also be interesting to have a function that creates an iterator based only on the Information, for example, multi_index::container(1)_index(2). Is there a function that calculates the max. index number of a certain container? Thank you very much, Alex Schuh -- No virus found in this outgoing message. Checked by AVG Anti-Virus.
