public XMLPersistenceMappingParser(JDBCConfiguration conf)
Constructor; supply configuration.

Method Detail

reset

protected void reset()
Description copied from class: CFMetaDataParser
Override this method to clear any state and ready the parser for a new document. Subclasses should call super.reset() to clear superclass state.

Overrides:
reset in class XMLPersistenceMetaDataParser

startSystemMappingElement

protected Object startSystemMappingElement(String name,

Description copied from class: XMLPersistenceMetaDataParser
Implement to parse a mapping element outside of any class.

Overrides:
startSystemMappingElement in class XMLPersistenceMetaDataParser
Returns:
the tag for the given element, or null to skip the element
Throws:
SAXException
