public interface Result<T>
This interface provides a return value for asynchronous Objectify calls, nearly the same as
java.util.concurrent.Future
. Unfortunately the methods ofFuture
throw checked exceptions, rendering the class prohibitively painful to use in business logic. This interface fixes that problem, and implementors automatically unwrap ExecutionExceptions (checked exceptions will be wrapped in a new RuntimeException).- Author:
