All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, org.w3c.dom.Element, org.w3c.dom.ElementTraversal, org.w3c.dom.events.EventTarget, org.w3c.dom.Node, org.w3c.dom.NodeList, org.w3c.dom.TypeInfo
Direct Known Subclasses:
DeferredElementNSImpl, PSVIElementNSImpl

public class ElementNSImpl
extends ElementImpl

ElementNSImpl inherits from ElementImpl 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 Detail

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
See Also:
AttrNSImpl, ElementNSImpl

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
Parameters:
prefix - The namespace prefix of this node, or null(empty string) if it is unspecified.
Throws:
INVALID_CHARACTER_ERR - Raised if the specified prefix contains an invalid character.
org.w3c.dom.DOMException
Since:
WD-DOM-Level-2-19990923
See Also:
AttrNSImpl, ElementNSImpl

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
See Also:
AttrNSImpl, ElementNSImpl

getXMLBaseAttribute

protected org.w3c.dom.Attr getXMLBaseAttribute()
NON-DOM Returns the xml:base attribute.

Overrides:
getXMLBaseAttribute in class ElementImpl

getTypeName

public java.lang.String getTypeName()
Specified by:
getTypeName in interface org.w3c.dom.TypeInfo
Overrides:
getTypeName in class ElementImpl
See Also:
TypeInfo.getTypeName()

getTypeNamespace

public java.lang.String getTypeNamespace()
Specified by:
getTypeNamespace in interface org.w3c.dom.TypeInfo
Overrides:
getTypeNamespace in class ElementImpl
See Also:
TypeInfo.getTypeNamespace()

isDerivedFrom

public boolean isDerivedFrom(java.lang.String typeNamespaceArg,
                             java.lang.String typeNameArg,
                             int derivationMethod)
Introduced in DOM Level 2.

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

Specified by:
isDerivedFrom in interface org.w3c.dom.TypeInfo
Overrides:
isDerivedFrom in class ElementImpl
Parameters:
typeNamespaceArg - The namspace of the ancestor type declaration
typeNameArg - The name of the ancestor type declaration
derivationMethod - The derivation method
Returns:
boolean True if the type is derived by restriciton for the reference type

setType

public void setType(org.apache.xerces.xs.XSTypeDefinition type)
NON-DOM: setting type used by the DOM parser

NodeImpl.setReadOnly(boolean, boolean)
