Class AccumulationXMLFilter

java.lang.Object
  org.xml.sax.helpers.XMLFilterImpl
      org.wikimodel.wem.xhtml.filter.DefaultXMLFilter
          org.wikimodel.wem.xhtml.filter.AccumulationXMLFilter

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler, org.xml.sax.ext.LexicalHandler, org.xml.sax.XMLFilter, org.xml.sax.XMLReader

public class AccumulationXMLFilter
extends DefaultXMLFilter

SAX parsers are allowed to call the characters() method several times in a row. Some parsers have a buffer of 8K (Crimson), others of 16K (Xerces) and others can even call onCharacters() for every single characters! Thus we need to accumulate the characters in a buffer before we process them. This filter does exactly this.
