## Class AttrNSImpl

- java.lang.Object
- - org.apache.xerces.dom.NodeImpl
  - - org.apache.xerces.dom.AttrImpl
    - - org.apache.xerces.dom.AttrNSImpl

- All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, org.w3c.dom.Attr, org.w3c.dom.events.EventTarget, org.w3c.dom.Node, org.w3c.dom.NodeList, org.w3c.dom.TypeInfo
  Direct Known 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 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`

      See Also:
        `AttrNSImpl`, `ElementNSImpl`

    - #### 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.
      Specified by:

    - #### 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

      Specified by:
        `isDerivedFrom` in interface `org.w3c.dom.TypeInfo`
      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.
      Specified by:
        `getTypeNamespace` in interface `org.w3c.dom.TypeInfo`
