Class AttrNSImpl

Implemented Interfaces:
Attr, Cloneable, EventTarget, Node, NodeList, Serializable, TypeInfo
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.

Method Details

getLocalName

public String getLocalName()
Introduced in DOM Level 2.

Returns the local part of the qualified name of this 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.

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.

Overrides:
getPrefix in interface NodeImpl
Since:
WD-DOM-Level-2-19990923

getTypeName

public String getTypeName()
Overrides:
getTypeName in interface AttrImpl
See Also:
org.w3c.dom.TypeInfo.getTypeName()

getTypeNamespace

public String getTypeNamespace()
Overrides:
getTypeNamespace in interface AttrImpl
See Also:
org.w3c.dom.TypeInfo.getTypeNamespace()

isDerivedFrom

public boolean isDerivedFrom(String typeNamespaceArg,
                             String typeNameArg,
                             int derivationMethod)
Introduced in DOM Level 3.

Checks if a type is derived from another by restriction. See: http://www.w3.org/TR/DOM-Level-3-Core/core.html#TypeInfo-isDerivedFrom

Overrides:
isDerivedFrom in interface AttrImpl
Parameters:
Returns:
boolean True if the type is derived by restriciton for the reference type

setPrefix

public void setPrefix(String prefix)
            throws 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.

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