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,
                      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
