Class ContentProcessor
java.lang.Object
org.outerj.daisy.publisher.serverimpl.docpreparation.ContentProcessor
- All Implemented Interfaces:
- org.xml.sax.ContentHandler
- public class ContentProcessor
- extends java.lang.Object
- implements org.xml.sax.ContentHandler
Processes special instructions in the content, such as queries
and includes.
A ContentProcessor can be instantiated recursively by the
IncludeProcessor: if the IncludeProcessor includes some content,
it will create a new ContentProcessor and push the content
through that ContentProcessor. ContentProcessors have a reference
to their parent processor so that recursive includes can be
detected.
