Objects implementing the NamedNodeMap interface are used to represent collections of nodes that can be accessed by name. Note that NamedNodeMap does not inherit from NodeList; NamedNodeMaps are not maintained in any particular order. Objects contained in an object implementing NamedNodeMap may also be accessed by an ordinal index, but this is simply to allow convenient enumeration of the contents of a NamedNodeMap, and does not imply that the DOM specifies an order to these Nodes. NamedNodeMap objects in the DOM are live. |
Default Constructor |
NamedNodeMap(GdomeNamedNodeMap* = 0) |
Creates a smart pointer for the Gdome element whose pointer is passed as an argument. The user should never pass a non-null pointer to this constructor. |
Copy and Cast Constructors |
NamedNodeMap(const
NamedNodeMap&)
|
These constructors can be used to copy a smart pointer or to downcast it. If the downcasting is not possible, the resulting smart pointer will be null. |
Copy Operator |
NamedNodeMap& operator=(const NamedNodeMap&) |
Equality |
bool operator==(const
NamedNodeMap&) const
bool operator!=(const NamedNodeMap&) const |
Two smart pointers are equal if they point to the same Gdome object. |
Attributes |
unsigned long get_length(void) const |
The number of nodes in this map. The range of valid child node indices is 0 to length-1 inclusive. |
Methods |
Node getNamedItem(const DOMString& name) |
Parameters:
Retrieves a node specified by name. |
Node setNamedItem(const Node& arg) |
Parameters:
Adds a node using its nodeName attribute. If a node with that name is already present in this map, it is replaced by the new one. 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. Exceptions:
|
Node removeNamedItem(const DOMString& name) |
Parameters:
Removes a node specified by name. When this map contains the attributes attached to an element, 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 when applicable. Exceptions:
|
Node item(const unsigned longindex) |
Parameters:
Returns the indexth item in the map. If index is greater than or equal to the number of nodes in this map, this returns null. |
Node getNamedItemNS(const DOMString& namespaceURI, const DOMString& localName) |
Parameters:
Retrieves a node specified by local name and namespace URI. HTML-only DOM implementations do not need to implement this method. |
Node setNamedItemNS(const Node& arg) |
Parameters:
Adds a node using its namespaceURI and localName. If a node with that namespace URI and that local name is already present in this map, it is replaced by the new one. HTML-only DOM implementations do not need to implement this method. Exceptions:
|
Node removeNamedItemNS(const DOMString& namespaceURI, const DOMString& localName) |
Parameters:
Removes a node specified by local name and namespace URI. A removed attribute may be known to have a default value when this map contains the attributes attached to an element, as returned by the attributes attribute of the Node interface. If so, an attribute immediately appears containing the default value as well as the corresponding namespace URI, local name, and prefix when applicable. HTML-only DOM implementations do not need to implement this method. Exceptions:
