Class TransformerHandlerImpl

java.lang.Object

net.sf.saxon.event.ReceivingContentHandler

net.sf.saxon.TransformerHandlerImpl

All Implemented Interfaces:

TransformerHandler, SourceLocator, LocationProvider, SaxonLocator, SourceLocationProvider, ContentHandler, DTDHandler, LexicalHandler, Locator

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.

Constructor Details

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 Details

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

Specified by:

setSystemId in interface TransformerHandler

getSystemId

public String getSystemId()

Get the systemId of the document

Specified by:

getSystemId in interface Locator

Specified by:

getSystemId in interface SourceLocator

Specified by:

getSystemId in interface TransformerHandler

Overrides:

getSystemId in class ReceivingContentHandler

Returns:

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

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

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
