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.- Author:

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 classProxyReceiver
- Parameters:
receiver
- the underlying receiver, the one that is to receive events after processing by this filter.
-
startElement
public void startElement(int nameCode, int typeCode, int locationId, int properties) throws XPathException
Output element start tag- Specified by:
startElement
in interfaceReceiver
- Overrides:
startElement
in classProxyReceiver
- 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 aLocationProvider
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
-
namespace
public void namespace(int namespaceCode, int properties) throws XPathException
Handle a namespace- Specified by:
namespace
in interfaceReceiver
- Overrides:
namespace
in classProxyReceiver
- Parameters:
namespaceCode
- an integer: the top half is a prefix code, the bottom half a URI code. These may be translated into an actual prefix and URI using the name pool. A prefix code of zero represents the empty prefix (that is, the default namespace). A URI code of zero represents a URI of "", that is, a namespace undeclaration.properties
- The most important property is REJECT_DUPLICATES. If this property is set, the namespace declaration will be rejected if it conflicts with a previous declaration of the same prefix. If the property is not set, the namespace declaration will be ignored if it conflicts with a previous declaration. This reflects the fact that when copying a tree, namespaces for child elements are emitted before the namespaces of their parent element. Unfortunately this conflicts with the XSLT rule for complex content construction, where the recovery action in the event of conflicts is to take the namespace that comes last. XSLT therefore doesn't recover from this error: it sets the REJECT_DUPLICATES flag, and this is treated as a hard error.- Throws:
XPathException
-
attribute
public void attribute(int nameCode, int typeCode, java.lang.CharSequence value, int locationId, int properties) throws XPathException
Handle an attribute- Specified by:
attribute
in interfaceReceiver
- Overrides:
attribute
in classProxyReceiver
- Parameters:
nameCode
- The name of the attribute, as held in the name pooltypeCode
- The type of the attribute, as held in the name poolvalue
- the string value of the attributelocationId
- an integer which can be interpreted using aLocationProvider
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
