This class is used to provide namespace context for XPath expression evaluation in the Seahawk data mapping rules file, and includes default mappings for prefixes such as moby:

Constructor Summary

NamespaceContextImpl()
Populates the mapping table with an assortment of prefixes and namespaces used in Moby (see MobyPrefixResolver)

NamespaceContextImpl(Node contextNode, String defaultNSPrefix)
Traverses up the DOM from the given element to enumerate all of the prefix <-> namespace mappings valid for this node.

NamespaceContextImpl(String ns, String nsPrefix)
Sets just one prefix, the one provided, which also gets mapped to the blank prefix

Method Summary

String	getNamespaceURI(String prefix)
String	getPrefix(String namespaceURI)
Iterator	getPrefixes(String namespaceURI)
void	setPrefix(String namespaceURI, String prefix)

NamespaceContextImpl

public NamespaceContextImpl(String ns,
                            String nsPrefix)
