The review of the Switch library by Steven Watanabe will begin this Saturday, Jan 5th.
Description:
The built in C/C++ switch statement is very efficient. Unfortunately, unlike a chained if/else construct there is no easy way to use it when the number of cases depends on a template parameter. The Switch
The attachment contains an alternative which uses no preprocessing. It uses more memory because of the static fun_vec in: fun_switch_impl::our_vec However, it would probably use less code because of no preprocessor generated switch statements. OTOH, it would be slower because the function has to be looked up in the vector. Are there any other comparisons you can think of. It would be useful to outline the pro's and cons of alternative implementations you've considered. I've done a simple test of the attached by using it in a slightly modified test_switch.cpp. I just added the #include and: BOOST_CHECK_EQUAL((fun_switch<test_range>(5, f())), 6); -regards, Larry
