Class AttributedCharacterSpanIterator

java.lang.Object

org.apache.batik.gvt.text.AttributedCharacterSpanIterator

All Implemented Interfaces:

java.lang.Cloneable, java.text.AttributedCharacterIterator, java.text.CharacterIterator

public class AttributedCharacterSpanIterator
extends java.lang.Object
implements java.text.AttributedCharacterIterator

AttributedCharacterSpanIterator Used to provide ACI functionality to a "substring" of an AttributedString. In this way a TextLayout can be created which only uses a substring of AttributedString.
