Class RIFFFilter  

java.lang.Object
  org.xml.sax.helpers.XMLFilterImpl
      org.esau.ptarmigan.impl.filter.BaseFilter
          org.esau.ptarmigan.impl.filter.BinaryFilter
              org.esau.ptarmigan.impl.filter.RIFFFilter

All Implemented Interfaces:

org.esau.ptarmigan.impl.ByteStreamSource, org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler, org.xml.sax.XMLFilter, org.xml.sax.XMLReader

public final class RIFFFilter

extends BinaryFilter

Extract metadata from a Resource Interchange File Format (RIFF) native tag format.

This doesn't produce any SAX events at present and merely jumps over RIFF to get to other data. However, it could be extended to produce SAX events describing the RIFF content.
