Class TransactionFilterHandler

java.lang.Object
  org.xml.sax.helpers.XMLFilterImpl
      org.geotools.filter.FilterFilter
          org.vfny.geoserver.requests.wfs.TransactionFilterHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler, org.geotools.gml.GMLHandlerFeature, org.geotools.gml.GMLHandlerJTS, org.xml.sax.XMLFilter, org.xml.sax.XMLReader

public class TransactionFilterHandler

extends org.geotools.filter.FilterFilter

implements org.geotools.gml.GMLHandlerFeature

Uses SAX to extact a Transactional request from and incoming XML stream. This class handles what should be done with geometries, if they should be passed to become part of a Feature, or if they should be an attribute in the Filter. These set of classes are fairly clunky and could probably be rewritten in geotools.

Empty constructor.

Method Summary

void	feature(org.geotools.feature.Feature feature) Recieves the feature for an insert request.
void	geometry(com.vividsolutions.jts.geom.Geometry geometry) Recieves the geometry from a child, and either passes it on to FilterFilter to add to the filter, or if not in a filter then it goes to the transaction handler.

Constructor Detail

TransactionFilterHandler

public TransactionFilterHandler(TransactionHandler parent,
                                org.geotools.feature.FeatureType schema)

Empty constructor.

Parameters:

parent - The handler to pass filters and features to.

schema - The schema (not used, this needs to be redone in geotools)

Method Detail

geometry

public void geometry(com.vividsolutions.jts.geom.Geometry geometry)

Recieves the geometry from a child, and either passes it on to FilterFilter to add to the filter, or if not in a filter then it goes to the transaction handler.

Specified by:

geometry in interface org.geotools.gml.GMLHandlerJTS

Parameters:

geometry - called by a child filter when it can not deal with it.

feature

public void feature(org.geotools.feature.Feature feature)

Recieves the feature for an insert request. Just passes it up to the transaction handler.

Specified by:

feature in interface org.geotools.gml.GMLHandlerFeature

Parameters:

feature - The feature read by child parsers.
