Remarks

TFunction

See the class definition for intended usage.

TFunction

A class which represents a copy of something callable. FuncType represents a function type and so TFunction should be defined as follows:

// A function taking a string and float and returning int32. Parameter names are optional. TFunction

Unlike TFunctionRef, this object is intended to be used like a UE version of std::function. That is, it takes a copy of whatever is bound to it, meaning you can return it from functions and store them in objects without caring about the lifetime of the original object being bound.

Example:

// Something.h TFunction GetTransform();

// Something.cpp TFunction GetTransform(const FString& Prefix) { // Squares number and returns it as a string with the specified prefix return = { return Prefix + TEXT(": ") + TTypeToString::ToString(Num * Num); }; }

// SomewhereElse.cpp #include "Something.h"

void Func() { TFunction Transform = GetTransform(TEXT("Hello"));

FString Result = Transform(5); // "Hello: 25" }
