| EmptyNumberFormatter | | public class EmptyNumberFormatter extends NumberFormatter (Code) | | In addition to its superclass NumberFormatter, 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 or -1.
Examples:
new EmptyNumberFormatter();
new EmptyNumberFormatter(-1);
