All Implemented Interfaces:
org.w3c.dom.Attr, java.lang.Cloneable, org.w3c.dom.events.EventTarget, org.w3c.dom.Node, org.w3c.dom.NodeList, java.io.Serializable
Direct Known Subclasses:
DeferredAttrNSImpl

public class AttrNSImpl
extends AttrImpl

AttrNSImpl inherits from AttrImpl and adds namespace support.

The qualified name is the node name, and we store localName which is also used in all queries. On the other hand we recompute the prefix when necessary.

                     java.lang.String namespaceURI,
                     java.lang.String qualifiedName)

                  java.lang.String namespaceURI,
                  java.lang.String qualifiedName,

Method Detail

setValues

public void setValues(CoreDocumentImpl ownerDocument,
                      java.lang.String namespaceURI,
                      java.lang.String qualifiedName,
                      java.lang.String localName)
NON-DOM: resets this node and sets specified values for the node

Parameters:
ownerDocument -
namespaceURI -
qualifiedName -
localName -

getNamespaceURI

public java.lang.String getNamespaceURI()
Introduced in DOM Level 2.

The namespace URI of this node, or null if it is unspecified.

This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.

For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

Specified by:
getNamespaceURI in interface org.w3c.dom.Node
Overrides:
getNamespaceURI in class NodeImpl
Since:
WD-DOM-Level-2-19990923
See Also:
AttrNSImpl, ElementNSImpl

getPrefix

public java.lang.String getPrefix()
Introduced in DOM Level 2.

The namespace prefix of this node, or null if it is unspecified.

For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

Specified by:
getPrefix in interface org.w3c.dom.Node
Overrides:
getPrefix in class NodeImpl
Since:
WD-DOM-Level-2-19990923

setPrefix

public void setPrefix(java.lang.String prefix)
               throws org.w3c.dom.DOMException
Introduced in DOM Level 2.

Note that setting this attribute changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.

Specified by:
setPrefix in interface org.w3c.dom.Node
Overrides:
setPrefix in class NodeImpl
Throws:
INVALID_CHARACTER_ERR - Raised if the specified prefix contains an invalid character.
org.w3c.dom.DOMException - INVALID_CHARACTER_ERR: Raised if the specified prefix contains an illegal character, per the XML 1.0 specification .
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
NAMESPACE_ERR: Raised if the specified prefix is malformed per the Namespaces in XML specification, if the namespaceURI of this node is null, if the specified prefix is "xml" and the namespaceURI of this node is different from "http://www.w3.org/XML/1998/namespace", if this node is an attribute and the specified prefix is "xmlns" and the namespaceURI of this node is different from " http://www.w3.org/2000/xmlns/", or if this node is an attribute and the qualifiedName of this node is "xmlns" .
Since:
WD-DOM-Level-2-19990923

getLocalName

public java.lang.String getLocalName()
Introduced in DOM Level 2.

Returns the local part of the qualified name of this node.

Specified by:
getLocalName in interface org.w3c.dom.Node
Overrides:
getLocalName in class NodeImpl
Since:
WD-DOM-Level-2-19990923
