AttributedCharacterIterator

implements CharacterIterator
java.text.AttributedCharacterIterator

Class Overview

Extends the CharacterIterator interface, adding support for iterating over attributes and not only characters. An AttributedCharacterIterator also allows the user to find runs and their limits. Runs are defined as ranges of characters that all have the same attributes with the same values.
