Method Summary

void	addUniqueAttribute(String qName, String value, int flags) Add a unique attribute
void	characters(Node node) This method gets the node's value as a String and uses that String as if it were an input character notification.
void	characters(String characters) Receive notification of character data.
void	comment(String comment) Receive notification of a comment.
void	error(SAXParseException exc)
void	fatalError(SAXParseException exc)
void	flushPending() This method flushes any pending events, which can be startDocument() closing the opening tag of an element, or closing an open CDATA section.
void	processingInstruction(String target, String data) Do nothing as this is an abstract class.
boolean	reset() Try's to reset the super class and reset this class for re-use, so that you don't need to create a new serializer (mostly for performance reasons).
void	setCdataSectionElements(Vector URI_and_localNames) Does nothing.
void	setContentHandler(ContentHandler _saxHandler) Sets the SAX ContentHandler.
void	setLexHandler(LexicalHandler _lexHandler) Sets the LexicalHandler.
void	setShouldOutputNSAttr(boolean doOutputNSAttr) Set whether or not namespace declarations (e.g.
void	setTransformState(TransformStateSetter ts) Pass in a reference to a TransformState object, which can be used during SAX ContentHandler events to obtain information about he state of the transformation.
void	startDTD(String arg0, String arg1, String arg2) Do nothing.
void	startElement(String qName) An element starts, but attributes are not fully known yet.
void	startElement(String uri, String localName, String qName) Receives notification that an element starts, but attributes are not fully known yet.
void	startElement(String arg0, String arg1, String arg2, Attributes arg3) Receive notification of the beginning of an element, although this is a SAX method additional namespace or attribute information can occur before or after this call, that is associated with this element.
void	warning(SAXParseException exc)

              throws SAXException

Do nothing.

Throws:

SAXException

See Also:

LexicalHandler.startDTD(String, String, String)

characters

public void characters(String characters)
                throws SAXException

Receive notification of character data.

Parameters:

characters - The string of characters to process.

Throws:

SAXException

See Also:

ExtendedContentHandler#characters(String)

comment

public void comment(String comment)
             throws SAXException

Receive notification of a comment.

Specified by:

comment in interface org.apache.xml.serializer.ExtendedLexicalHandler

Overrides:

comment in class SerializerBase

Throws:

SAXException

See Also:

ExtendedLexicalHandler#comment(String)

processingInstruction

public void processingInstruction(String target,
                                  String data)
                           throws SAXException

Do nothing as this is an abstract class. All subclasses will need to define their behavior if it is different.

Throws:

SAXException

See Also:

ContentHandler.processingInstruction(String, String)

startElement

public void startElement(String arg0,
                         String arg1,
                         String arg2,
                         Attributes arg3)
                  throws SAXException

Receive notification of the beginning of an element, although this is a SAX method additional namespace or attribute information can occur before or after this call, that is associated with this element.

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

SAXException

ContentHandler.startElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes), ContentHandler.endElement(java.lang.String, java.lang.String, java.lang.String), AttributeList, ContentHandler.startElement(String,String,String,Attributes)

setLexHandler

public void setLexHandler(LexicalHandler _lexHandler)

Sets the LexicalHandler.

Parameters:

_lexHandler - The LexicalHandler to set

setContentHandler

public void setContentHandler(ContentHandler _saxHandler)

Sets the SAX ContentHandler.

Parameters:

_saxHandler - The ContentHandler to set

See Also:

Serializer.asContentHandler(), ToSAXHandler

setCdataSectionElements

public void setCdataSectionElements(Vector URI_and_localNames)

Does nothing. The setting of CDATA section elements has an impact on stream serializers.

Parameters:

URI_and_localNames - pairs of namespace URI and local names that identify elements whose text elements are to be output as CDATA sections. The namespace of the local element must be the given URI to match. The qName is not given because the prefix does not matter, only the namespace URI to which that prefix would map matters, so the prefix itself is not relevant in specifying which elements have their text to be output as CDATA sections.

See Also:

XSLOutputAttributes.setCdataSectionElements(java.util.Vector)

setShouldOutputNSAttr

public void setShouldOutputNSAttr(boolean doOutputNSAttr)

Set whether or not namespace declarations (e.g. xmlns:foo) should appear as attributes of elements

Parameters:

doOutputNSAttr - whether or not namespace declarations should appear as attributes

flushPending

public void flushPending()
                  throws SAXException

This method flushes any pending events, which can be startDocument() closing the opening tag of an element, or closing an open CDATA section.

Throws:

SAXException

setTransformState

public void setTransformState(TransformStateSetter ts)

Pass in a reference to a TransformState object, which can be used during SAX ContentHandler events to obtain information about he state of the transformation. This method will be called before each startDocument event.

Parameters:

ts - A reference to a TransformState object

startElement

public void startElement(String uri,
                         String localName,
                         String qName)

Parameters:

uri - the URI of the namespace of the element (optional)

localName - the element name, but without prefix (optional)

qName - the element name, with prefix, if any (required)

Throws:

SAXException
