Class DescribeHandler

java.lang.Object
  org.xml.sax.helpers.XMLFilterImpl
      org.vfny.geoserver.requests.wfs.DescribeHandler

All Implemented Interfaces:

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 class DescribeHandler

extends org.xml.sax.helpers.XMLFilterImpl

implements org.xml.sax.ContentHandler

Uses SAX to extact a DescribeFeatureType query from and incoming GetFeature request XML stream.

Note that this Handler extension ignores Filters completely and must be chained as a parent to the PredicateFilter method in order to recognize them. If it is not chained, it will still generate valid queries, but with no filtering whatsoever.
