Class DefaultHandler2

Implemented Interfaces:
ContentHandler, DeclHandler, DTDHandler, EntityResolver, EntityResolver2, ErrorHandler, LexicalHandler
public class DefaultHandler2
extends DefaultHandler
implements LexicalHandler, DeclHandler, EntityResolver2
This class extends the SAX2 base handler class to support the SAX2 LexicalHandler, DeclHandler, and EntityResolver2 extensions. Except for overriding the original SAX1 resolveEntity() method the added handler methods just return. Subclassers may override everything on a method-by-method basis.
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.

Note: this class might yet learn that the ContentHandler.setDocumentLocator() call might be passed a Locator2 object, and that the ContentHandler.startElement() call might be passed a Attributes2 object.

Since:
SAX 2.0 (extensions 1.1 alpha)

Constructor Summary

DefaultHandler2()
Constructs a handler which ignores all parsing events.

            throws SAXException
Specified by:
endEntity in interface LexicalHandler

externalEntityDecl

public void externalEntityDecl(String name,
                               String publicId,
                               String systemId)
            throws SAXException
Specified by:

getExternalSubset

public InputSource getExternalSubset(String name,
                                     String baseURI)
            throws SAXException,
                   IOException
Tells the parser that if no external subset has been declared in the document text, none should be used.
Specified by:
getExternalSubset in interface EntityResolver2

internalEntityDecl

public void internalEntityDecl(String name,
                               String value)
            throws SAXException
Specified by:
internalEntityDecl in interface DeclHandler

resolveEntity

public InputSource resolveEntity(String publicId,
                                 String systemId)
            throws SAXException,
                   IOException
Invokes EntityResolver2.resolveEntity() with null entity name and base URI. You only need to override that method to use this class.
Specified by:
resolveEntity in interface EntityResolver
Overrides:
resolveEntity in interface DefaultHandler

resolveEntity

public InputSource resolveEntity(String name,
                                 String publicId,
                                 String baseURI,

            throws SAXException,
                   IOException
Tells the parser to resolve the systemId against the baseURI and read the entity text from that resulting absolute URI. Note that because the older DefaultHandler.resolveEntity(), method is overridden to call this one, this method may sometimes be invoked with null name and baseURI, and with the systemId already absolutized.
Specified by:
resolveEntity in interface EntityResolver2

            throws SAXException
Specified by:
startCDATA in interface LexicalHandler
