Explicitly Constructing Functors and Runnables

In the following code segment, a functor and threaded runnable instance are explicitly constructed:

Example 2 – Constructing a threaded runnable from a functor

// Construct a functor that invokes hello

RWTFunctor<void()> myFunctor = hello; // 1

// Construct a runnable that invokes functor

RWThreadFunction myThread; // 2

myThread = RWThreadFunction::make(myFunctor); // 3

//1 Constructs a handle instance for a functor object and binds it to the function hello().

//2 Constructs an empty RWThreadFunction handle instance.

//3 Constructs and initializes an RWThreadFunctionImp body instance, then binds that instance to the handle instance, myThread.

The code creates a threaded runnable that, when started, launches a thread that invokes the functor instance to execute the hello() function.
