All known Subclasses: com.jgoodies.validation.formatter.RelativeDateFormatter,
| EmptyDateFormatter | | public class EmptyDateFormatter extends DateFormatter (Code) | | In addition to its superclass DateFormatter, this class converts
to/from the empty string. Therefore it holds an empty value
that is the counterpart of the empty string.
The Method #valueToString converts the empty value to the
empty string. And #stringToValue converts blank strings
to the empty value. In all other cases the conversion is delegated
to its superclass.
Often the empty value is null. As an alternative you can map
the empty string to a given date, for example epoch (January 1, 1970).
Examples:
new EmptyDateFormatter();
new EmptyDateFormatter(new Date(0));
