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.The
TransformerHandler
is written on the assumption that it is receiving events from a parser configured withhttp://xml.org/sax/features/namespaces
set to true andhttp://xml.org/sax/features/namespace-prefixes
set to false. TheTransformerHandler
has no control over the feature settings of the sender of the events (which is not even necessarily anXMLReader
), and if the events do not follow this pattern then the class may fail in unpredictable ways.

Constructor Detail
-
TransformerHandlerImpl
protected TransformerHandlerImpl(TransformerImpl transformer)
Create a TransformerHandlerImpl and initialise variables. The constructor is protected, because the Filter should be created using newTransformerHandler() in the SAXTransformerFactory class- Parameters:
transformer
- the Controller to be used
-
-
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 interfaceContentHandler
- Overrides:
startDocument
in classReceivingContentHandler
- Throws:
SAXException
- only if an overriding subclass throws this exceptionUnsupportedOperationException
- 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 interfaceTransformerHandler
-
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 theReceivingContentHandler.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 interfaceTransformerHandler
- 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 theReceivingContentHandler.setDocumentLocator(org.xml.sax.Locator)
method if available, otherwise the SystemId passed to thesetSystemId(String)
method.- Specified by:
getSystemId
in interfaceTransformerHandler
-
setResult
public void setResult(Result result)
Set theResult
associated with thisTransformerHandler
to be used for the transformation.- Specified by:
setResult
in interfaceTransformerHandler
- Parameters:
result
- AResult
instance, should not benull
.- Throws:
IllegalArgumentException
- if result is invalid for some reason.
-
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 interfaceContentHandler
- Overrides:
endDocument
in classReceivingContentHandler
- Throws:
SAXException
