public class XMLRecordHandler

extends HierarchicalHandler

A SAX Event handler that takes over when a parent handler realizes that we have a record element. This handler then fills in a record's fields on the basis of the SAX events it receives. This handler only handles a single record.

Field Summary

Fields inherited from class org.oreodata.xml.HierarchicalHandler

parentHandler, parser

Constructor Summary

protected	XMLRecordHandler(HierarchicalHandler parent, Record record, boolean recurse) Use this constructor if you are handing off control to the handler and already know the record type.
protected	XMLRecordHandler(org.xml.sax.XMLReader parser, Record record, boolean recurse) Use this constructor if this is the root handler and the Record is being fed in as a standalone XML document.

Constructor Detail

XMLRecordHandler

protected XMLRecordHandler(org.xml.sax.XMLReader parser,
                           Record record,
                           boolean recurse)

Use this constructor if this is the root handler and the Record is being fed in as a standalone XML document.

Parameters:

parser - The source of the SAX events.

recurse - Do we recurse into nested records?

XMLRecordHandler

protected XMLRecordHandler(HierarchicalHandler parent,
                           Record record,
                           boolean recurse)

Use this constructor if you are handing off control to the handler and already know the record type. i.e. you've already parsed the <rec_type blah blah> bit.

Parameters:

parent - The parent handler to return control to.

recurse - Do we recurse into nested records?
