T- The value type of the resolved Promise passed as input to this callback.
R- The value type of the returned Promise from this callback.
@ConsumerType public interface Success<T,R>
This is a functional interface and can be used as the assignment target for a lambda expression or method reference.
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
Promise.then(Success) when this Success callback was
registered as the chained Promise.
If the returned Promise is
null then the chained Promise must
resolve immediately with a successful value of
null. If the
returned Promise is not
null then the chained Promise must be
resolved when the returned Promise is resolved.
