Dear Boost.MultiIndex user: I've completed a major update of Boost.MultiIndex retrievable from the SVN repository, trunk branch, or at: https://www.dropbox.com/s/xipv129az88vgd1/multi_index_130713.zip This update includes many C++11 capabilities (most emulated by various means in pre-C++11 compilers,) among them the following: * multi_index_container is now efficiently movable employee_set extract_employees(const std::string& db); employee_set cont=extract_employees("employees.dat"); // no data copying * Initializer lists supported (if the compiler provides them) employee_set es8{{0,"Rose",40,4512},{1,"Mary",38,3345},{2,"Jo",25,7102}}; * Emplace functions es.emplace(0,"Joe",31,1123); es.get<3>().emplace_back(3,"Judy",39,6201); * Non-copyable elements allowed typeded multi_index_container< std::unique_ptr<employee>, indexed_by<...>
employee_ptr_set;
How does this update affect you? 1. Of course, you can now begin using the new capabilities, even in non-C++11 compilers with some limitations (explained at the documentation). 2. Your code can get some transparent performance gain without you doing anything es.insert(employee(4,"Jill",52,3379)); // temporary's moved rather than copied 3. The internal code has been refactored to implement the new features, and this refactoring touches on preexisting functionality, hopefully without producing regressions --this has been thoroughly tested, but: It is now #3 that worries me the most: if you use Boost.MultiIndex and have some time to test this preview with your code, please do so and report the results. The more this update is tested before the official release, the less problems it will cause (ideally none.) As the update is major, every bit of testing helps. Hope you enjoy the new features.
