Class XmlNamespaceDictionary (1.42.3)

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");

Methods

getAliasForUri(String uri)

public synchronized String getAliasForUri(String uri)

Returns the namespace alias (or "" for the default namespace) for the given namespace URI.

Parameter

Name	Description
`uri`	`String` namespace URI

Returns

Type	Description
`String`

getAliasToUriMap()

public synchronized Map<String,String> getAliasToUriMap()

Returns an unmodified set of map entries for the map from namespace alias (or "" for the default namespace) to namespace URI.

Returns

Type	Description
`Map<String,String>`

getUriForAlias(String alias)

public synchronized String getUriForAlias(String alias)

Returns the namespace URI for the given namespace alias (or "" for the default namespace).

Parameter

Name	Description
`alias`	`String` namespace alias (or `""` for the default namespace)

Returns

Type	Description
`String`

getUriToAliasMap()

`Map<String,String>`

serialize(XmlSerializer serializer, String elementName, Object element)

public void serialize(XmlSerializer serializer, String elementName, Object element)

Shows a debug string representation of an element data object of key/value pairs.

Parameters

Name	Description
`serializer`	`org.xmlpull.v1.XmlSerializer`
`elementName`	`String` XML element local name prefixed by its namespace alias
`element`	`Object` element data object (GenericXml, Map, or any object with public fields)

Exceptions

Type	Description
`IOException`	I/O exception

serialize(XmlSerializer serializer, String elementNamespaceUri, String elementLocalName, Object element)

public void serialize(XmlSerializer serializer, String elementNamespaceUri, String elementLocalName, Object element)

Shows a debug string representation of an element data object of key/value pairs.

Parameters

Name	Description
`serializer`	`org.xmlpull.v1.XmlSerializer`
`elementNamespaceUri`	`String` XML namespace URI or `null` for no namespace
`elementLocalName`	`String` XML local name
`element`	`Object` element data object (GenericXml, Map, or any object with public fields)

Exceptions

Type	Description
`IOException`	I/O exception

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.

Parameters

Name	Description
`alias`	`String` alias or `null` to remove the namespace URI
`uri`	`String` namespace URI or `null` to remove the namespace alias

Returns

Type	Description
`XmlNamespaceDictionary`	this namespace dictionary

toStringOf(String elementName, Object element)

public String toStringOf(String elementName, Object element)

Shows a debug string representation of an element data object of key/value pairs.

Parameters

Name	Description
`elementName`	`String` optional XML element local name prefixed by its namespace alias -- for example `"atom:entry"` -- or `null` to make up something
`element`	`Object` element data object (GenericXml, Map, or any object with public fields)

Returns

Type	Description
`String`
