Direct Known Subclasses:

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.

INTERNAL:

Usage of this class is not supported. It may be altered or removed at any time.

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.

Overrides:
getNamespaceURI in class NodeImpl
Since:
WD-DOM-Level-2-19990923

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.

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.

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

getLocalName

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

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

Overrides:
getLocalName in class NodeImpl
Since:
WD-DOM-Level-2-19990923

getTypeName

public java.lang.String getTypeName()
Description copied from interface: org.w3c.dom.TypeInfo
The name of a type declared for the associated element or attribute, or null if unknown.
Overrides:
getTypeName in class AttrImpl
See Also:
TypeInfo.getTypeName()

isDerivedFrom

public boolean isDerivedFrom(java.lang.String typeNamespaceArg,
                             java.lang.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 class AttrImpl
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

getTypeNamespace

public java.lang.String getTypeNamespace()
Description copied from interface: org.w3c.dom.TypeInfo
The namespace of the type declared for the associated element or attribute or null if the element does not have declaration or if no namespace information is available.
Overrides:
getTypeNamespace in class AttrImpl
See Also:
TypeInfo.getTypeNamespace()
