        public AtomicValue convert​(AtomicValue input)
        Description copied from class: Converter
        Convert an atomic value from the source type to the target type
        Specified by:
        convert in class Converter.UnfailingConverter
        input - the atomic value to be converted, which the caller guarantees to be of the appropriate type for the converter. The results are undefined if the value is of the wrong type; possible outcomes are (apparent) success, or a ClassCastException.
        the result of the conversion, as an AtomicValue, if conversion succeeds, or a ValidationFailure object describing the reasons for failure if conversion is not possible. Note that the ValidationFailure object is not (and does not contain) an exception, because it does not necessarily result in an error being thrown, and creating exceptions on non-failure paths is expensive.
