Method Summary

void	closeParser() Closes the parser
void	error(SAXParseException exception) Rethrows the given exception
void	fatalError(SAXParseException exception) Ignore this since an error is called immediately afterwards
void	flush() This function is called when the parser is closing to serialize the in memory DOM tree, for a connector in add/update mode
boolean	getOmitXMLDeclaration() Returns whether we omit XML declaration or not.
String	getVersion() Version information.
void	initInput() This function is called as a part of parser initialization, when the connector having this parser is in Iterator mode
void	initOutput() This function is called as a part of parser initialization, when the connector having this parser is in Add mode
void	initParser() This function is called by the connector containing this parser
Entry	readEntry() Constructs the next entry from the data structure read in initially.
void	registerScriptBeans(ScriptEngine se) Registers "static" script variables for input or output Document in the given ScriptEngine with the name "xmldom"
void	setOmitXMLDeclaration(boolean omit) Sets whether to omit XML declaration or not.
void	warning(SAXParseException err) Logs the given warning
void	writeEntry(Entry entry) Constructs the data structure from the next entry read in initially.

Registers "static" script variables for input or output Document in the given ScriptEngine with the name "xmldom"

Specified by:

registerScriptBeans in interface ParserInterface

Overrides:

registerScriptBeans in class ParserImpl

Parameters:

se - ScriptEngine

Throws:

Exception - if an error occurs.

initParser

public void initParser()
                throws Exception

This function is called by the connector containing this parser

Specified by:

initParser in interface ParserInterface

Overrides:

initParser in class ParserImpl

Throws:

Exception - if an error occurs.

closeParser
