I wanted to create system that allow me in easy way iterate over them and execute. After some time I created this implementation: template<ECommands::enum cmd> bool execCommandTemp(ECommands::ENUM a_cmd, void* a_data) { if (a_cmd == cmd) { SCommand<cmd>::execute((SCommand ::SData*)a_data); return false; } return execCommandTemp<(ECommands::ENUM)(cmd+1)>(a_cmd, a_data); } template<> bool execCommandTemp<ECommands::WRAP>(ECommands::ENUM a_cmd, void* a_data) { return true; } bool execCommand( ECommands::ENUM a_cmd, void* a_data ) { return execCommandTemp<(ECommands::ENUM)0>(a_cmd, a_data); } where SCommand look in example such a way: template <> st...
