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.

Constructor Detail

### ElementNSImpl

    protected ElementNSImpl(CoreDocumentImpl ownerDocument,
                            java.lang.String namespaceURI,
                            java.lang.String qualifiedName)
                     throws DOMException

  DOM2: Constructor for Namespace implementation.

### ElementNSImpl

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

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 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
  Throws:
    INVALID_CHARACTER_ERR - Raised if the specified prefix contains an invalid character.
  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
