bodhidharma.xml_parsing.ParseFileHandler
bodhidharma.xml_parsing.ParseTaxonomyFileHandler
public class ParseTaxonomyFileHandler
An extension of the Xerces XML DefaultHandler
class that implements the SAX ContentHandler
.
The methods of this class are called by an instance of an
XMLReader
while it is parsing an XML document.
This particular implementation is custom designed to parse
XML files of the taxonomy_file type used by the Bodhidharma
music classification system. A custom exceptions is thrown
if the file is not of this type. At the end of parsing,
the contents of the file elements are stored in the
parsed_file_contents field as a one element array holding
a DefaultTreeModel
.
