Detailed Description

Use std::tuple as tuple type.

This file contains helper functions for working with std::tuples. The functions DispatchToMethod and DispatchToFunction take a function pointer or instance and method pointer, and unpack a tuple into arguments to the call.

Example usage:

  // These two methods of creating a Tuple are identical.
  std::tuple<int, const char*> tuple_a(1, "wee");
  std::tuple<int, const char*> tuple_b = std::make_tuple(1, "wee");

  void SomeFunc(int a, const char* b) { }
  DispatchToFunction(&SomeFunc, tuple_a);  // SomeFunc(1, "wee")
  DispatchToFunction(
      &SomeFunc, std::make_tuple(10, "foo"));    // SomeFunc(10, "foo")

  struct { void SomeMeth(int a, int b, int c) { } } foo;
  DispatchToMethod(&foo, &Foo::SomeMeth, std::make_tuple(1, 2, 3));
  // foo->SomeMeth(1, 2, 3);
