Class AttrNSImpl

Implemented Interfaces:
org.w3c.dom.Attr, Cloneable, Serializable, TypeInfo, org.w3c.dom.events.EventTarget, org.w3c.dom.Node, org.w3c.dom.NodeList
Known Direct Subclasses:
DeferredAttrNSImpl, PSVIAttrNSImpl

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.

                  String qualifiedName,
                  String localName)

Method Details

getLocalName

public 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 interface NodeImpl

Since:
WD-DOM-Level-2-19990923


getNamespaceURI

public 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 interface NodeImpl

Since:
WD-DOM-Level-2-19990923


getPrefix

public 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 interface NodeImpl

Since:
WD-DOM-Level-2-19990923


getTypeName

public String getTypeName()
Overrides:
getTypeName in interface AttrImpl

See Also:
org.apache.xerces.dom3.TypeInfo.getTypeName()


getTypeNamespace

public String getTypeNamespace()
Overrides:
getTypeNamespace in interface AttrImpl

See Also:
org.apache.xerces.dom3.TypeInfo.getTypeNamespace()


isDerivedFrom

public boolean isDerivedFrom(String typeNamespaceArg,
                             String typeNameArg,
                             int derivationMethod)
DOM Level 3 Experimental
Overrides:
isDerivedFrom in interface AttrImpl

See Also:
org.apache.xerces.dom3.TypeInfo.isDerivedFrom()


setPrefix

public void setPrefix(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 interface NodeImpl

Parameters:
prefix - The namespace prefix of this node, or null(empty string) if it is unspecified.

Throws:
org.w3c.dom.DOMException -

Since:
WD-DOM-Level-2-19990923


setValues

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

Parameters:
ownerDocument -
namespaceURI -
qualifiedName -
localName -
