public final class XmlNamespaceDictionary
Beta
Thread-safe XML namespace dictionary that provides a one-to-one map of namespace alias to URI.
Implementation is thread-safe. For maximum efficiency, applications should use a single globally-shared instance of the XML namespace dictionary.
A namespace alias is uniquely mapped to a single namespace URI, and a namespace URI is uniquely mapped to a single namespace alias. In other words, it is not possible to have duplicates.
Sample usage:
static final XmlNamespaceDictionary DICTIONARY = new XmlNamespaceDictionary()
.set("", "http://www.w3.org/2005/Atom")
.set("activity", "http://activitystrea.ms/spec/1.0/")
.set("georss", "http://www.georss.org/georss")
.set("media", "http://search.yahoo.com/mrss/")
.set("thr", "http://purl.org/syndication/thread/1.0");

set(String alias, String uri)
public synchronized XmlNamespaceDictionary set(String alias, String uri)
Adds a namespace of the given alias and URI.
If the uri is null
, the namespace alias will be removed. Similarly, if the alias is
null
, the namespace URI will be removed. Otherwise, if the alias is already mapped to a
different URI, it will be remapped to the new URI. Similarly, if a URI is already mapped to a
different alias, it will be remapped to the new alias.
