Examples of org.apache.batik.gvt.text.AttributedCharacterSpanIterator

org.apache.batik.gvt.text.AttributedCharacterSpanIterator
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. @author Bill Haneman @version $Id: AttributedCharacterSpanIterator.java,v 1.6 2003/03/14 21:53:19 nsochele Exp $
