Examples of com.ibm.icu.text.NumberFormat$Field

com.ibm.icu.text.NumberFormat
The instances of this inner class are used as attribute keys and values in AttributedCharacterIterator that NumberFormat.formatToCharacterIterator() method returns.
There is no public constructor to this class, the only instances are the constants defined here.
