Class TransformerReceiver

java.lang.Object
  net.sf.saxon.event.SequenceReceiver
      net.sf.saxon.event.ProxyReceiver
          net.sf.saxon.event.TransformerReceiver

All Implemented Interfaces:

Result, Receiver

public class TransformerReceiver
extends ProxyReceiver

TransformerReceiver is similar in concept to the JAXP TransformerHandler, except that it implements Saxon's Receiver interface rather than the standard SAX2 interface. This means that it allows nodes with type annotations to be passed down a pipeline from one transformation to another.

Constructor Summary

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

Method Summary

void	close() Override the behaviour of close() in ProxyReceiver, so that it fires off the transformation of the constructed document
Result	getResult() Get the output destination of the transformation
Transformer	getTransformer() Get the Transformer used for this transformation
void	open() Start of event stream
void	setResult(Result result) Set the output destination of the transformation.
void	setSystemId(String systemId) Set the SystemId of the document

Constructor Detail

TransformerReceiver

public TransformerReceiver(Controller controller)

Create a TransformerReceiver and initialise variables.

Parameters:

controller - the Controller (Saxon's implementation of the JAXP Transformer)

Method Detail

open

public void open()
          throws XPathException

Start of event stream

Specified by:

open in interface Receiver

Overrides:

open in class ProxyReceiver

Throws:

XPathException - if an error occurs

getTransformer

public Transformer getTransformer()

Get the Transformer used for this transformation

Returns:

the transformer (which will always be an instance of Controller)

setSystemId

public void setSystemId(String systemId)

Set the SystemId of the document

Specified by:

setSystemId in interface Result

Specified by:

setSystemId in interface Receiver

Overrides:

setSystemId in class ProxyReceiver

Parameters:

systemId - the URI used to identify the tree being passed across this interface

setResult

public void setResult(Result result)

Set the output destination of the transformation. This method must be called before the transformation can proceed.

Parameters:

result - the destination to which the transformation output will be written

getResult

public Result getResult()

Get the output destination of the transformation

Returns:

the output destination. May be null if no destination has been set.

close

public void close()
           throws XPathException

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

Specified by:

close in interface Receiver

Overrides:

close in class ProxyReceiver

Throws:

XPathException - if an error occurs
