Class XMLReader

java.lang.Object

org.eclipse.persistence.internal.oxm.record.XMLReader

All Implemented Interfaces:

XMLReader

Direct Known Subclasses:

XMLReaderAdapter

public class XMLReader
extends Object
implements XMLReader

INTERNAL:

Purpose:Provide a wrapper for an org.xml.sax.XMLReader instance and define some extra event methods that can be used by TopLink during the unmarshal process. These events are no ops in this class, but may be overridden in subclasses.

Responsibilities

• Wrap an instance of org.xml.sax.XMLReader and provide all the required API
• Provide empty implementations of some callback methods that can be overridden in subclasses

Since:

release specific (what release of product did this appear in)

• DOMReader
