public class PullNamespaceReducer extends PullFilter implements NamespaceResolver
This class is derived from, and contains much common code with, the NamespaceReducer in the push pipeline. (In the push version, however, namespace fixup is not performed by the NamespaceReducer, but by the ComplexContentOutputter).

Attributes may be read before or after reading the namespaces of an element, but must not be read after the first child node has been read, or after calling one of the methods skipToEnd(), getStringValue(), or getTypedValue().

- if a dynamic error occurspublic NamespaceBinding[] getNamespaceDeclarations() throws XPathException
This class extends the semantics of the PullProvider interface by allowing this method to be called also after an END_ELEMENT event. This is to support PullToStax, which requires this functionality. In this situation it returns the namespaces declared on the startElement associated with the element that has just ended.
It is permissible for this method to return namespace declarations that are redundant.
The NamespaceDeclarations object is guaranteed to remain unchanged until the next START_ELEMENT event, but may then be overwritten. The object should not be modified by the client.
Namespaces may be read before or after reading the attributes of an element, but must not be read after the first child node has been read, or after calling one of the methods skipToEnd(), getStringValue(), or getTypedValue().
