Package net.sf.saxon.event

Class NamePoolConverter

java.lang.Object

net.sf.saxon.event.SequenceReceiver

net.sf.saxon.event.ProxyReceiver

net.sf.saxon.event.NamePoolConverter

All Implemented Interfaces:

javax.xml.transform.Result, Receiver

public class NamePoolConverter
extends ProxyReceiver

This class is a filter that passes all Receiver events through unchanged, except that it changes namecodes to allow for the source and the destination using different NamePools. This is necessary when a stylesheet has been constructed as a general document (e.g. as the result of a transformation) and is passed to newTemplates() to be compiled as a stylesheet.

Constructor Detail

NamePoolConverter

public NamePoolConverter(Receiver next,
                         NamePool oldPool,
                         NamePool newPool)

Constructor

Parameters:

next - the next receiver in the pipeline

oldPool - the old namepool

newPool - th new namepool

Method Detail

setUnderlyingReceiver

public void setUnderlyingReceiver(Receiver receiver)

Set the underlying emitter. This call is mandatory before using the Emitter. This version is modified from that of the parent class to avoid setting the namePool of the destination Receiver.

Overrides:

setUnderlyingReceiver in class ProxyReceiver

Parameters:

receiver - the underlying receiver, the one that is to receive events after processing by this filter.

startElement

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

Output element start tag

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 - if an error occurs

namespace

public void namespace(NamespaceBinding namespaceBinding,
                      int properties)
               throws XPathException

Handle a namespace

Specified by:

namespace in interface Receiver

Overrides:

namespace in class ProxyReceiver

Parameters:

namespaceBinding - the prefix/uri pair representing the namespace binding

properties - any special properties to be passed on this call

Throws:

XPathException - if an error occurs

attribute

public void attribute(NodeName nameCode,
                      SimpleType typeCode,
                      java.lang.CharSequence value,
                      int locationId,
                      int properties)
               throws XPathException

Handle an attribute

Specified by:

attribute in interface Receiver

Overrides:

attribute in class ProxyReceiver

Parameters:

nameCode - The name of the attribute, as held in the name pool

typeCode - The type of the attribute, as held in the name pool

value - the string value of the attribute

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:

DISABLE_ESCAPING

Disable escaping for this attribute

NO_SPECIAL_CHARACTERS

Attribute value contains no special characters

Throws:

XPathException - if an error occurs
