Examples of IMarkupWriter

org.apache.tapestry.IMarkupWriter
Defines an object that can write markup (XML, HTML, XHTML) style output. A IMarkupWriter handles translation from unicode to the markup language (escaping characters such as '<' and '>' to their entity equivalents, '<' and '>') as well as assisting with nested elements, closing tags, etc. @author Howard Ship, David Solis @version $Id: IMarkupWriter.java 243791 2004-02-19 17:38:13Z hlship $
