All Implemented Interfaces:

Result, Receiver

public class ImplicitResultChecker
extends ProxyReceiver

This filter is inserted into the serializer pipeline when serializing an implicit XSLT result tree, that is, one that is created without use of xsl:result-document. Its main purpose is to check, if and only if the result destination is actually written to, that it does not conflict with an explicit result destination with the same URI. It also ensures that the output destination is opened before it is first written to.

Constructor Detail

ImplicitResultChecker

public ImplicitResultChecker(Receiver next,
                             Controller controller)

Create an ImplicitResultChecker. This is a filter on the output pipeline.

Parameters:

next - the next receiver on the pipeline

controller - the controller of the XSLT transformation

Method Detail

open

public void open()
          throws XPathException

Description copied from class: ProxyReceiver

Start of event stream

Specified by:

open in interface Receiver

Overrides:

open in class ProxyReceiver

Throws:

XPathException

startDocument

public void startDocument(int properties)
                   throws XPathException

Description copied from class: ProxyReceiver

Start of a document node.

Specified by:

startDocument in interface Receiver

Overrides:

startDocument in class ProxyReceiver

Parameters:

properties - bit-significant integer indicating properties of the document node. The definitions of the bits are in class ReceiverOptions

Throws:

XPathException

startElement

public void startElement(int nameCode,
                         int typeCode,
                         int locationId,
                         int properties)
                  throws XPathException

Description copied from class: ProxyReceiver

Notify the start of an element

Specified by:

startElement in interface Receiver

Overrides:

startElement in class ProxyReceiver

Parameters:

nameCode - integer code identifying the name of the element within the name pool.

typeCode - integer code identifying the element's type within the name pool.

locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - properties of the element node

Throws:

XPathException

characters

public void characters(CharSequence chars,

Description copied from class: ProxyReceiver

Character data

Specified by:

characters in interface Receiver

Overrides:

characters in class ProxyReceiver

Parameters:

chars - The characters

locationId - an integer which can be interpreted using a LocationProvider to return information such as line number and system ID. If no location information is available, the value zero is supplied.

properties - Bit significant value. The following bits are defined:
