## Member Function Documentation

unsigned int XercesNamedNodeMapWrapper::getLength ( | ) const`[virtual]`

| The number of nodes in the map. The range of valid child node indices is 0 to `length-1` inclusive. Reimplemented from XalanNamedNodeMap.

XalanNode * XercesNamedNodeMapWrapper::getNamedItem ( | const XalanDOMString & name ) const`[virtual]`

  | Retrieves a node specified by name. Parameters:
  name | The `nodeName` of a node to retrieve.
Returns: A `DOMNode` (of any type) with the specified `nodeName`, or `null` if it does not identify any node in the map. Reimplemented from XalanNamedNodeMap.

XalanNode * XercesNamedNodeMapWrapper::getNamedItemNS ( | const XalanDOMString & namespaceURI,
| const XalanDOMString & localName ) const`[virtual]`

  | Retrieves a node specified by local name and namespace URI. Parameters:
  namespaceURI | The namespace URI of the node to retrieve.
  localName | The local name of the node to retrieve.
Returns: A `DOMNode` (of any type) with the specified local name and namespace URI, or `null` if they do not identify any node in the map. Reimplemented from XalanNamedNodeMap.

XalanNode * XercesNamedNodeMapWrapper::item ( | unsigned int index ) const`[virtual]`

  | Returns the `index`th item in the map. If `index` is greater than or equal to the number of nodes in the map, this returns `null`. Parameters:
  index | Index into the map.
Returns: The node at the `index`th position in the `NamedNodeMap`, or `null` if that is not a valid index. Reimplemented from XalanNamedNodeMap.

XalanNode * XercesNamedNodeMapWrapper::removeNamedItem ( | const XalanDOMString & name )`[virtual]`

  | Removes a node specified by name. If the removed node is an `Attr` with a default value it is immediately replaced. Parameters:
  name | The `nodeName` of a node to remove.
  Returns: The node removed from the map or `null` if no node with such a name exists. Exceptions:
  DOMException | NOT_FOUND_ERR: Raised if there is no node named `name` in the map. NO_MODIFICATION_ALLOWED_ERR: Raised if this `NamedNodeMap` is readonly.
Reimplemented from XalanNamedNodeMap.

XalanNode * XercesNamedNodeMapWrapper::removeNamedItemNS ( | const XalanDOMString & namespaceURI,
| const XalanDOMString & localName )`[virtual]`

  | Removes a node specified by local name and namespace URI. Parameters:
  namespaceURI | The namespace URI of the node to remove.
  localName | The local name of the node to remove. When this `DOMNamedNodeMap` contains the attributes attached to an element, as returned by the attributes attribute of the `DOMNode` interface, if the removed attribute is known to have a default value, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix.
  Returns: The node removed from the map if a node with such a local name and namespace URI exists. Exceptions:
  DOMException | NOT_FOUND_ERR: Raised if there is no node named `name` in the map. NO_MODIFICATION_ALLOWED_ERR: Raised if this `NamedNodeMap` is readonly.
Reimplemented from XalanNamedNodeMap.

XalanNode * XercesNamedNodeMapWrapper::setNamedItem ( | XalanNode * arg )`[virtual]`

  | Adds a node using its `nodeName` attribute. As the `nodeName` attribute is used to derive the name which the node must be stored under, multiple nodes of certain types (those that have a "special" string value) cannot be stored as the names would clash. This is seen as preferable to allowing nodes to be aliased. Parameters:
  arg | A node to store in a named node map. The node will later be accessible using the value of the `nodeName` attribute of the node. If a node with that name is already present in the map, it is replaced by the new one.
  Returns: If the new `Node` replaces an existing node the replaced `Node` is returned, otherwise `null` is returned. Exceptions:
  DOMException | WRONG_DOCUMENT_ERR: Raised if `arg` was created from a different document than the one that created the `NamedNodeMap`. NO_MODIFICATION_ALLOWED_ERR: Raised if this `NamedNodeMap` is readonly. INUSE_ATTRIBUTE_ERR: Raised if `arg` is an `Attr` that is already an attribute of another `Element` object. The DOM user must explicitly clone `Attr` nodes to re-use them in other elements.
Reimplemented from XalanNamedNodeMap.

XalanNode * XercesNamedNodeMapWrapper::setNamedItemNS ( | XalanNode * arg )`[virtual]`

  | Adds a node using its `namespaceURI` and `localName`. Parameters:
  arg | A node to store in a named node map. The node will later be accessible using the value of the `namespaceURI` and `localName` attribute of the node. If a node with those namespace URI and local name is already present in the map, it is replaced by the new one.
  Returns: If the new `Node` replaces an existing node the replaced `Node` is returned, otherwise `null` is returned. Exceptions:
  DOMException | WRONG_DOCUMENT_ERR: Raised if `arg` was created from a different document than the one that created the `NamedNodeMap`. NO_MODIFICATION_ALLOWED_ERR: Raised if this `NamedNodeMap` is readonly. INUSE_ATTRIBUTE_ERR: Raised if `arg` is an `Attr` that is already an attribute of another `Element` object. The DOM user must explicitly clone `Attr` nodes to re-use them in other elements.
Reimplemented from XalanNamedNodeMap.
