Class AddMediaContentHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      magoffin.matt.ma2.web.service.AddMediaContentHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler

public final class AddMediaContentHandler
extends org.xml.sax.helpers.DefaultHandler

ContentHandler implementation that splits the XML document into one XML document and one Base64-decoded zip archive from the element.

Low-level SAX is used for parsing here to efficiently parse potentially huge Base64 character streams from large zip archives. StAX is used to copy the SAX events to an XMLStreamWriter.
