Class Inheritance
Imports
java.text.AttributedCharacterIterator, .AttributedString, .FieldPosition, .Format.Field, com.ibm.icu.text.ConstrainedFieldPosition, .ListFormatter, .NumberFormat, .UFormat, .UnicodeSet
Implementation of FormattedValue based on FormattedStringBuilder. The implementation currently revolves around numbers and number fields. However, it can be generalized in the future when there is a need. In C++, this implements FormattedValue. In Java, it is a stateless collection of static functions to avoid having to use nested objects.
