template<typename FuncType, typename... Types> decltype(auto) TransformTuple (     TTuple < Types... > && Tuple,     FuncType Func )

Remarks

Creates a new TTuple by applying a functor to each of the elements.

Example:

float Overloaded(int32 Arg); char Overloaded(const TCHAR* Arg); const TCHAR* Overloaded(const FString& Arg);

void Func(const TTuple& MyTuple) { // Equivalent to: // TTuple TransformedTuple(Overloaded(MyTuple.Get<0>()), Overloaded(MyTuple.Get<1>()), Overloaded(MyTuple.Get<2>()))); auto TransformedTuple = TransformTuple(MyTuple, const auto& Arg { return Overloaded(Arg); }); } A new tuple of the transformed elements.
