Class TransformerHandlerImpl

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

All Implemented Interfaces:

TransformerHandler, ContentHandler, DTDHandler, LexicalHandler

public class TransformerHandlerImpl
extends ReceivingContentHandler
implements 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.

Method Summary

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

Method Detail

startDocument

public void startDocument()
                   throws 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 ContentHandler

Overrides:

startDocument in class ReceivingContentHandler

Throws:

SAXException - only if an overriding subclass throws this exception

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

getTransformer

public Transformer getTransformer()

Get the Transformer used for this transformation

Specified by:

getTransformer in interface TransformerHandler

setSystemId

public void setSystemId(String url)

Set the SystemId of the document. Note that in reporting location information, Saxon gives priority to the system Id reported by the SAX Parser in the Locator passed to the ReceivingContentHandler.setDocumentLocator(org.xml.sax.Locator) method. The SystemId passed to this method is used as the base URI for resolving relative references.

Specified by:

setSystemId in interface TransformerHandler

Parameters:

url - the systemId of the source document

getSystemId

public String getSystemId()

Get the systemId of the document. This will be the systemId obtained from the Locator passed to the ReceivingContentHandler.setDocumentLocator(org.xml.sax.Locator) method if available, otherwise the SystemId passed to the setSystemId(String) method.

Specified by:

getSystemId in interface TransformerHandler

setResult

public void setResult(Result result)

Set the output destination of the transformation

Specified by:

setResult in interface TransformerHandler

getResult

public Result getResult()

Get the output destination of the transformation

Returns:

the output destination

endDocument

public void endDocument()
                 throws SAXException

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

Specified by:

endDocument in interface ContentHandler

Overrides:

endDocument in class ReceivingContentHandler

Throws:

SAXException
