Class TransformerHandlerImpl

java.lang.Object
  net.sf.saxon.event.ReceivingContentHandler
      net.sf.saxon.TransformerHandlerImpl

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.ext.LexicalHandler, LocationProvider, org.xml.sax.Locator, SaxonLocator, javax.xml.transform.SourceLocator, javax.xml.transform.sax.TransformerHandler

public class TransformerHandlerImpl

extends ReceivingContentHandler

implements javax.xml.transform.sax.TransformerHandler

TransformerHandlerImpl implements the javax.xml.transform.sax.TransformerHandler interface. It acts as a ContentHandler and LexicalHandler which receives a stream of SAX events representing an input document, and performs a transformation treating this SAX stream as the source document of the transformation.

Constructor Summary

protected

TransformerHandlerImpl(Controller controller) Create a TransformerHandlerImpl and initialise variables.

Method Summary

void	endDocument() Override the behaviour of endDocument() in ReceivingContentHandler, so that it fires off the transformation of the constructed document
javax.xml.transform.Result	getResult() Get the output destination of the transformation
java.lang.String	getSystemId() Get the systemId of the document
javax.xml.transform.Transformer	getTransformer() Get the Transformer used for this transformation
void	setResult(javax.xml.transform.Result result) Set the output destination of the transformation
void	setSystemId(java.lang.String url) Set the SystemId of the document
void	startDocument() Start of a new document.

Constructor Detail

TransformerHandlerImpl

protected TransformerHandlerImpl(Controller controller)

Create a TransformerHandlerImpl and initialise variables. The constructor is protected, because the Filter should be created using newTransformerHandler() in the SAXTransformerFactory class

Method Detail

startDocument

public void startDocument()
                   throws org.xml.sax.SAXException

Start of a new document. The TransformerHandler is not serially reusable, so this method must only be called once.

Specified by:

startDocument in interface org.xml.sax.ContentHandler

Overrides:

startDocument in class ReceivingContentHandler

Throws:

org.xml.sax.SAXException - only if an overriding subclass throws this exception

java.lang.UnsupportedOperationException - if an attempt is made to reuse the TransformerHandler by calling startDocument() more than once.

getTransformer

public javax.xml.transform.Transformer getTransformer()

Get the Transformer used for this transformation

Specified by:

getTransformer in interface javax.xml.transform.sax.TransformerHandler

setSystemId

public void setSystemId(java.lang.String url)

Set the SystemId of the document

Specified by:

setSystemId in interface javax.xml.transform.sax.TransformerHandler

getSystemId

public java.lang.String getSystemId()

Get the systemId of the document

Specified by:

getSystemId in interface javax.xml.transform.sax.TransformerHandler

Overrides:

getSystemId in class ReceivingContentHandler

Returns:

A string containing the system identifier, or null if none is available.

setResult

public void setResult(javax.xml.transform.Result result)

Set the output destination of the transformation

Specified by:

setResult in interface javax.xml.transform.sax.TransformerHandler

getResult

public javax.xml.transform.Result getResult()

Get the output destination of the transformation

endDocument

public void endDocument()
                 throws org.xml.sax.SAXException

Override the behaviour of endDocument() in ReceivingContentHandler, so that it fires off the transformation of the constructed document

Specified by:

endDocument in interface org.xml.sax.ContentHandler

Overrides:

endDocument in class ReceivingContentHandler

Throws:

org.xml.sax.SAXException
