| Method Detail |
startDocument
public void startDocument()
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - 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).
endDocument
public void endDocument()
throws org.xml.sax.SAXException
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - 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).
characters
public void characters(char[] chars,
int start,
int length)
throws org.xml.sax.SAXException
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - 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).
startElement
public void startElement(java.lang.String uri, java.lang.String name, java.lang.String qname, org.xml.sax.Attributes attributes) throws org.xml.sax.SAXException
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - 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).
endElement
public void endElement(java.lang.String uri, java.lang.String name, java.lang.String qname) throws org.xml.sax.SAXException
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - 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).
ignorableWhitespace
public void ignorableWhitespace(char[] ch,
int start,
int length)
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - 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).
error
public void error(org.xml.sax.SAXParseException exc) throws org.xml.sax.SAXException
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - 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
public void fatalError(org.xml.sax.SAXParseException exc) throws org.xml.sax.SAXException
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - 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.
warning
public void warning(org.xml.sax.SAXParseException exc)
- Description copied from class:
org.xml.sax.helpers.DefaultHandler - Receive notification of a parser warning.
The default implementation does nothing. Application writers may override this method in a subclass to take specific actions for each warning, such as inserting the message in a log file or printing it to the console.
