Examples of java.text.Format$FieldDelegate

java.text.Format
FieldDelegate is notified by the various Format implementations as they are formatting the Objects. This allows for storage of the individual sections of the formatted String for later use, such as in a FieldPosition or for an AttributedCharacterIterator.
Delegates should NOT assume that the Format will notify the delegate of fields in any particular order. @see FieldPosition.Delegate @see CharacterIteratorFieldDelegate
