Class NamespaceResolver

java.lang.Object

ddf.util.NamespaceResolver

All Implemented Interfaces:

NamespaceContext

public class NamespaceResolver
extends Object
implements NamespaceContext

DDF namespace resolver loads all registered NamespaceMap interfaces and builds two HashMaps: one for namespace URIs to prefixes, and one for namespace prefixes to URIs. If there are multiple entries found for a single URI or prefix, the last one loaded from the OSGi Service Registry will be the one used.
