SAXWriter

public SAXWriter(EventStore es)

Default constructor.

Parameters:

es - event store for parse events

Method Detail

reset

public void reset()

Specified by:

startDocument in interface org.xml.sax.ContentHandler

Throws:

org.xml.sax.SAXException

endDocument

public void endDocument()

End of document handler. Writes end of document to event store.

Specified by:

endDocument in interface org.xml.sax.ContentHandler

startElement

public void startElement(java.lang.String uri,
