- All Implemented Interfaces:
- Serializable
- Enclosing class:
- DateFormat
Defines constants that are used as attribute keys in the
 
AttributedCharacterIterator returned
 from DateFormat.formatToCharacterIterator and as
 field identifiers in FieldPosition.
 The class also provides two methods to map between its constants and the corresponding Calendar constants.
