Method Detail

startDocumentInternal

protected void startDocumentInternal()
                              throws org.xml.sax.SAXException
Receive notification of the beginning of a document.

The SAX parser will invoke this method only once, before any other methods in this interface or in DTDHandler (except for setDocumentLocator).

Overrides:
startDocumentInternal in class SerializerBase
Throws:
org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
org.xml.sax.SAXException

endDocument

public void endDocument()
                 throws org.xml.sax.SAXException
Receive notification of the end of a document.

The SAX parser will invoke this method only once, and it will be the last method invoked during the parse. The parser shall not invoke this method until it has either abandoned parsing (because of an unrecoverable error) or reached the end of input.

Throws:
org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
org.xml.sax.SAXException

startElement

public void startElement(java.lang.String namespaceURI,
                         java.lang.String localName,
                         java.lang.String name,
                         org.xml.sax.Attributes atts)
                  throws org.xml.sax.SAXException
Receive notification of the beginning of an element.

The Parser will invoke this method at the beginning of every element in the XML document; there will be a corresponding endElement() event for every startElement() event (even when the element is empty). All of the element's content will be reported, in order, before the corresponding endElement() event.

If the element name has a namespace prefix, the prefix will still be attached. Note that the attribute list provided will contain only attributes with explicit values (specified or defaulted): #IMPLIED attributes will be omitted.

Specified by:
startElement in interface org.xml.sax.ContentHandler
Overrides:
startElement in class ToStream
Parameters:
namespaceURI - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.
localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.
name - The qualified name (with prefix), or the empty string if qualified names are not available.
atts - The attributes attached to the element, if any.
Throws:
org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
org.xml.sax.SAXException
See Also:
endElement(java.lang.String, java.lang.String, java.lang.String), AttributeList

endElement

public void endElement(java.lang.String namespaceURI,
                       java.lang.String localName,
                       java.lang.String name)
                throws org.xml.sax.SAXException
Receive notification of the end of an element.

The SAX parser will invoke this method at the end of every element in the XML document; there will be a corresponding startElement() event for every endElement() event (even when the element is empty).

If the element name has a namespace prefix, the prefix will still be attached to the name.

Specified by:
endElement in interface org.xml.sax.ContentHandler
Overrides:
endElement in class ToStream
Parameters:
namespaceURI - The Namespace URI, or the empty string if the element has no Namespace URI or if Namespace processing is not being performed.
localName - The local name (without prefix), or the empty string if Namespace processing is not being performed.
name - The qualified name (with prefix), or the empty string if qualified names are not available.
Throws:
org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
org.xml.sax.SAXException

characters

public void characters(char[] ch,
                       int start,
                       int length)
                throws org.xml.sax.SAXException
Receive notification of character data.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).

Specified by:
characters in interface org.xml.sax.ContentHandler
Overrides:
characters in class ToStream
Parameters:
ch - The characters from the XML document.
start - The start position in the array.
length - The number of characters to read from the array.
Throws:
org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
See Also:
ignorableWhitespace(char[], int, int), Locator

charactersRaw

public void charactersRaw(char[] ch,
                          int start,
                          int length)
                   throws org.xml.sax.SAXException
If available, when the disable-output-escaping attribute is used, output raw text without escaping.

Overrides:
charactersRaw in class ToStream
Parameters:
ch - The characters from the XML document.
start - The start position in the array.
length - The number of characters to read from the array.
Throws:
org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

writeNormalizedChars

                          int start,
                          int length,
                          boolean useLineSep)
                    throws java.io.IOException,
                           org.xml.sax.SAXException
Normalize the characters, but don't escape. Different from SerializerToXML#writeNormalizedChars because it does not attempt to do XML escaping at all.

Parameters:
ch - The characters from the XML document.
start - The start position in the array.
length - The number of characters to read from the array.
useLineSep - true if the operating systems end-of-line separator should be output rather than a new-line character.
Throws:
java.io.IOException
org.xml.sax.SAXException

cdata

public void cdata(char[] ch,
                  int start,
                  int length)
           throws org.xml.sax.SAXException
Receive notification of cdata.

The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Note that some parsers will report whitespace using the ignorableWhitespace() method rather than this one (validating parsers must do so).

Overrides:
cdata in class ToStream
Parameters:
ch - The characters from the XML document.
start - The start position in the array.
length - The number of characters to read from the array.
Throws:
org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.
See Also:
ignorableWhitespace(char[], int, int), Locator

ignorableWhitespace

public void ignorableWhitespace(char[] ch,
                                int start,

                         throws org.xml.sax.SAXException
Receive notification of ignorable whitespace in element content.

Validating Parsers must use this method to report each chunk of ignorable whitespace (see the W3C XML 1.0 recommendation, section 2.10): non-validating parsers may also use this method if they are capable of parsing and using content models.

SAX parsers may return all contiguous whitespace in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity, so that the Locator provides useful information.

The application must not attempt to read from the array outside of the specified range.

Specified by:
ignorableWhitespace in interface org.xml.sax.ContentHandler
Overrides:
ignorableWhitespace in class ToStream
Parameters:
ch - The characters from the XML document.
start - The start position in the array.

                           throws org.xml.sax.SAXException
Receive notification of a processing instruction.

The Parser will invoke this method once for each processing instruction found: note that processing instructions may occur before or after the main document element.
