Method Summary

void	characters(char[] ch, int start, int length) Checks if inside parsed element and adds its contents to appropriate variable.
void	endElement(java.lang.String namespaceURI, java.lang.String localName, java.lang.String rawName) Notes the end of the element exists query or bounding box.
void	feature(org.geotools.feature.Feature feature) Gets a feature and adds it to the list of current features, to be added to the insert request when it finishes.
void	filter(org.geotools.filter.Filter filter) Gets a filter and adds it to the appropriate query (or queries).
void	geometry(com.vividsolutions.jts.geom.Geometry geometry) If no children claim the geometry it comes here, and is used if we are looking for a value for a property element.
TransactionRequest	getRequest() Returns the Transaction request.
void	startElement(java.lang.String namespaceURI, java.lang.String localName, java.lang.String rawName, org.xml.sax.Attributes atts) Notes the start of the element and sets type names and query attributes.

                  throws org.xml.sax.SAXException

Notes the start of the element and sets type names and query attributes.

Specified by:

startElement in interface org.xml.sax.ContentHandler

Parameters:

namespaceURI - URI for namespace appended to element.

localName - Local name of element.

rawName - Raw name of element.

atts - Element attributes.

Throws:

org.xml.sax.SAXException - When the XML is not well formed.
