callSuccess callback for a Promise.
This method is called if the Promise with which it is registered resolves successfully.
In the remainder of this description we will refer to the Promise returned by this method as the returned Promise and the Promise returned by
Promise.then(Success)when this Success callback was registered as the chained Promise.
If the returned Promise is
nullthen the chained Promise must resolve immediately with a successful value of
null. If the returned Promise is not
nullthen the chained Promise must be resolved when the returned Promise is resolved.
