NamedNodeMapImpl

public NamedNodeMapImpl()

Method Details

getLength

public int getLength()
The number of nodes in this map. The range of valid child node indices is 0 to length-1 inclusive.


getNamedItem

public Node getNamedItem(String name)
Retrieves a node specified by name.

Parameters:
name - The nodeName of a node to retrieve.

Returns:
A Node (of any type) with the specified nodeName, or null if it does not identify any node in this map.


getNamedItemNS

public Node getNamedItemNS(String namespaceURI,
                           String localName)
Retrieves a node specified by local name and namespace URI.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

Parameters:
namespaceURI - The namespace URI of the node to retrieve.
localName - The local name of the node to retrieve.

Returns:
A Node (of any type) with the specified local name and namespace URI, or null if they do not identify any node in this map.

Since:
DOM Level 2


item

public Node item(int index)
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.

Parameters:
index - Index into this map.

Returns:
The node at the indexth position in the map, or null if that is not a valid index.


removeNamedItem

public Node removeNamedItem(String name)
            throws DOMException
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.

Parameters:
name - The nodeName of the node to remove.

Returns:
The node removed from this map if a node with such a name exists.


removeNamedItemNS

public Node removeNamedItemNS(String namespaceURI,
                              String localName)
            throws DOMException
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.
Documents which do not support the "XML" feature will permit only the DOM Level 1 calls for creating/setting elements and attributes. Hence, if you specify a non-null namespace URI, these DOMs will never find a matching node.

Parameters:
namespaceURI - The namespace URI of the node to remove.
localName - The local name of the node to remove.

Returns:
The node removed from this map if a node with such a local name and namespace URI exists.

Since:
DOM Level 2


setNamedItem

public Node setNamedItem(Node arg)
            throws DOMException
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.

Parameters:
arg - A node to store in this map. The node will later be accessible using the value of its nodeName attribute.

Returns:
If the new Node replaces an existing node the replaced Node is returned, otherwise null is returned.


setNamedItemNS

public Node setNamedItemNS(Node arg)
            throws DOMException
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.

Parameters:
arg - A node to store in this map. The node will later be accessible using the value of its namespaceURI and localName attributes.

Returns:
If the new Node replaces an existing node the replaced Node is returned, otherwise null is returned.

Since:
DOM Level 2
