Deprecated
since 1.5.
This class works with the deprecated
DocumentHandler
interface. It has been replaced by the SAX2
DefaultHandler
class.
This class implements the default behavior for four SAX1
interfaces: EntityResolver, DTDHandler, DocumentHandler,
and ErrorHandler. It is now obsolete, but is included in SAX2 to
support legacy SAX1 applications. SAX2 applications should use
the DefaultHandler
class instead.
Application writers can extend this class when they need to implement only part of an interface; parser writers can instantiate this class to provide default handlers when the application has not supplied its own.
Note that the use of this class is optional.

|---|---|
| public void characters(char[] ch, int start, int length) throws SAXException Implements org. Receive notification of character data inside an element. By default, do nothing. Application writers may override this method to take specific actions for each chunk of character data (such as adding the data to a node or buffer, or printing it to a file).
| |
| endDocument | back to summary |
|---|---|
| public void endDocument() throws SAXException Implements org. Receive notification of the end of the document. By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of a document (such as finalising a tree or closing an output file).
| |
| endElement | back to summary |
|---|---|
| public void endElement(String name) throws SAXException Implements org. Receive notification of the end of an element. By default, do nothing. Application writers may override this method in a subclass to take specific actions at the end of each element (such as finalising a tree node or writing output to a file).
| |
| error | back to summary |
|---|---|
| public void error(SAXParseException e) throws SAXException Implements org. Receive notification of a recoverable parser error. The default implementation does nothing. Application writers may override this method in a subclass to take specific actions for each error, such as inserting the message in a log file or printing it to the console.
| |
| fatalError | back to summary |
|---|---|
| public void fatalError(SAXParseException e) throws SAXException Implements org. Report a fatal XML parsing error. The default implementation throws a SAXParseException. Application writers may override this method in a subclass if they need to take specific actions for each fatal error (such as collecting all of the errors into a single report): in any case, the application must stop all regular processing when this method is invoked, since the document is no longer reliable, and the parser may no longer report parsing events.
| |
| ignorableWhitespace | back to summary |
|---|---|
| public void ignorableWhitespace(char[] ch, int start, int length) throws SAXException Implements org. Receive notification of ignorable whitespace in element content. By default, do nothing. Application writers may override this method to take specific actions for each chunk of ignorable whitespace (such as adding data to a node or buffer, or printing it to a file).
| |
| notationDecl | back to summary |
|---|---|
| public void notationDecl(String name, String publicId, String systemId) Implements org. Receive notification of a notation declaration. By default, do nothing. Application writers may override this method in a subclass if they wish to keep track of the notations declared in a document.
| |
| processingInstruction | back to summary |
|---|---|
| public void processingInstruction(String target, String data) throws SAXException Implements org. Receive notification of a processing instruction. By default, do nothing. Application writers may override this method in a subclass to take specific actions for each processing instruction, such as setting status variables or invoking other methods.
| |
| resolveEntity | back to summary |
|---|---|
| public InputSource resolveEntity(String publicId, String systemId) throws SAXException Implements org. Resolve an external entity. Always return null, so that the parser will use the system identifier provided in the XML document. This method implements the SAX default behaviour: application writers can override it in a subclass to do special translations such as catalog lookups or URI redirection.
| |
| setDocumentLocator | back to summary |
|---|---|
| public void setDocumentLocator(Locator locator) Implements org. Receive a Locator object for document events. By default, do nothing. Application writers may override this method in a subclass if they wish to store the locator for use with other document events.
| |
| startDocument | back to summary |
|---|---|
| public void startDocument() throws SAXException Implements org. Receive notification of the beginning of the document. By default, do nothing. Application writers may override this method in a subclass to take specific actions at the beginning of a document (such as allocating the root node of a tree or creating an output file).
| |
| startElement | back to summary |
|---|---|
| public void startElement(String name, AttributeList attributes) throws SAXException Implements org. References Deprecated
See corresponding docs for further information. Receive notification of the start of an element. By default, do nothing. Application writers may override this method in a subclass to take specific actions at the start of each element (such as allocating a new tree node or writing output to a file).

| unparsedEntityDecl | back to summary |
|---|---|
| public void unparsedEntityDecl(String name, String publicId, String systemId, String notationName) Implements org. Receive notification of an unparsed entity declaration. By default, do nothing.
