All Implemented Interfaces:

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.

The type annotations of nodes passed through this filter must be built-in types in the XSD namespace, because user-defined types belong to a specific Configuration and cannot readily be transferred. In practice the class is used only for untyped trees.
