org.eclipse.persistence.internal.oxm.record.XMLReaderAdapter

org.eclipse.persistence.internal.oxm.record.DOMReader

All Implemented Interfaces:

XMLReader

Direct Known Subclasses:

XMLFragmentReader

public class DOMReader
extends XMLReaderAdapter

INTERNAL:

Purpose: An implementation of XMLReader for parsing DOM Nodes into SAX events.

Responsibilities:

• Walk the DOM tree and report sax events to the provided content handler
• Report lexical events to the lexical handler if it's provided
• Listen for callbacks from the Mapping-Level framework to handle caching nodes for document preservation

Method Detail

parse

public void parse(InputSource input)
           throws SAXException

Specified by:

parse in interface XMLReader

Overrides:

parse in class XMLReader

Throws:

SAXException

parse

public void parse(Node node,
                  String newURI,
                  String newName)
           throws SAXException

Throws:

SAXException

parse

public void parse(Node node)
           throws SAXException

Throws:

SAXException

processParentNamespaces

protected void processParentNamespaces(Element element)
                                throws SAXException

Process namespace declarations on parent elements if not the root. For each parent node from current to root push each onto a stack, then pop each off, calling startPrefixMapping for each XMLNS attribute. Using a stack ensures that the parent nodes are processed top down.

Parameters:

element -

Throws:

SAXException

reportElementEvents

protected void reportElementEvents(Element elem)
                            throws SAXException

Throws:

SAXException

reportElementEvents

protected void reportElementEvents(Element elem,
                                   String newUri,
                                   String newName)
                            throws SAXException

Throws:

SAXException

buildAttributeList

protected DOMReader.IndexedAttributeList buildAttributeList(Element elem)
                                                     throws SAXException

Throws:

SAXException

endPrefixMappings

protected void endPrefixMappings(Element elem)
                          throws SAXException

Throws:

protected String getQName(Element elem)
                   throws SAXException

Throws:

SAXException

handleNewNamespaceDeclaration

protected void handleNewNamespaceDeclaration(Element elem,
                                             String emptyString,
                                             String value)

protected void handlePrefixedAttribute(Element elem)
                                throws SAXException

Handle prefixed attribute - may need to declare the namespace URI locally.

Throws:

SAXException

                           Mapping selfRecordMapping)

An EclipseLink specific callback into the Reader. This allows Objects to be associated with the XML Nodes they came from.

Overrides:

newObjectEvent in class XMLReader
