Invoke() [1/3]

template<typename FuncType , typename... ArgTypes>

FORCEINLINE auto Invoke	(	FuncType &&	Func,
		ArgTypes &&...	Args ) -> decltype(Forward<FuncType>(Func)(Forward<ArgTypes>(Args)...))

Invokes a callable with a set of arguments. Allows the following:

• Calling a functor object given a set of arguments.
• Calling a function pointer given a set of arguments.
• Calling a member function given a reference to an object and a set of arguments.
• Calling a member function given a pointer (including smart pointers) to an object and a set of arguments.
• Projecting via a data member pointer given a reference to an object.
• Projecting via a data member pointer given a pointer (including smart pointers) to an object.
