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.

  DOM2: localName.

Constructor Detail

### AttrNSImpl

    public AttrNSImpl()

### AttrNSImpl

    protected AttrNSImpl(CoreDocumentImpl ownerDocument,
                         java.lang.String namespaceURI,
                         java.lang.String qualifiedName)

  DOM2: Constructor for Namespace implementation.

### AttrNSImpl

    public AttrNSImpl(CoreDocumentImpl ownerDocument,
                      java.lang.String namespaceURI,
                      java.lang.String qualifiedName,
                      java.lang.String localName)

### AttrNSImpl

    protected AttrNSImpl(CoreDocumentImpl ownerDocument,
                         java.lang.String value)

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.

  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()`
