gnu.java.beans.decoder

Class PersistenceParser

Implemented Interfaces:
gnu.java.beans.decoder.Context

public class PersistenceParser
extends DefaultHandler
implements gnu.java.beans.decoder.Context

The PersistenceParser parses an XML data stream and delegates actions to ElementHandler instances. The parser catches and recovers from all exception which reside from wrong usage of attributes and tags.

Constructor Summary

PersistenceParser(InputStream inputStream, ExceptionListener exceptionListener, ClassLoader cl, XMLDecoder decoder)
Creates a PersistenceParser which reads XML data from the given InputStream, reports exceptions to ExceptionListener instance, stores resulting object in the DecoderContext and uses the given ClassLoader to resolve classes.

Method Summary

void
addParameterObject(Object o)
Adds a decoded object to the Context.
void
characters(char[] ch, int start, int length)
Transfers character data to the current handler
