I\'m trying to find a method to iterate over an a pack variadic template argument list. Now as with all iterations, you need some sort of method of knowing how many arguments are in the packed list开发
I recently created this example code to illustrate C++11 variadic template function usage. template <typename Head, typename... Tail> void foo (Head, Tail...);
I just implemented the quick sort algorithm by using C++11 variadic templates to evaluate it at compilation time. However, I encounter a performance issue when the data set is too large.
Given a variadic macro of the form: #define MY_CALL_RETURN_F(FType, FId, ...) \\ if(/*prelude omitted*/) {\\
I\'ve been frustrated by a simple variadic template function: constexpr size_t num_args () { return 0; }
Is it possible to construct function call (inside function template) with variable number of arguments, depending on number of template arguments? Something like:
What is the precedence of the meta-operator ... whose job is to unpack template type parameter packs? I imagine it\'s pretty low, but how low is it? The C++ standard says:
I am hitting this problem for some time now and I can\'t figure out how to solve it. The context is a reflection system in c++. A slim down explication of the problem is this. I have those 2 structs.
Is there a well-known way for simulating the variadic template feature in C#? For instance, I\'d like to write a method that takes a lambda with an arbitrary set of parameters. Here is in pseudo code
For silly reasons I\'ll not go into here, I need the commented out line to work and the line above it it to not work:
