NamedNodeMapImpl

public NamedNodeMapImpl(SimpleNode n)
Method Detail

getNamedItem

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

Specified by:
getNamedItem in interface NamedNodeMap
Parameters:
name - Name of a node to retrieve.
Returns:
A Node (of any type) with the specified name, or null if the specified name did not identify any node in the map.

setNamedItem

public Node setNamedItem(Node arg)
                  throws DOMException
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.

Specified by:
setNamedItem in interface NamedNodeMap
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 with the same name the previously existing Node is returned, otherwise null is returned.
Throws:
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.

removeNamedItem

public Node removeNamedItem(java.lang.String name)
                     throws DOMException
Removes a node specified by name. If the removed node is an Attr with a default value it is immediately replaced.

Specified by:
removeNamedItem in interface NamedNodeMap
Parameters:
name - The name of a node to remove.
Returns:
The node removed from the map or null if no node with such a name exists.
Throws:
DOMException - NOT_FOUND_ERR: Raised if there is no node named name in the map.

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 the map, this returns null.

Specified by:
item in interface NamedNodeMap
Parameters:
index - Index into the map.
Returns:
The node at the indexth position in the NamedNodeMap, or null if that is not a valid index.

getLength

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

Specified by:
getLength in interface NamedNodeMap

getNamedItemNS

public Node getNamedItemNS(java.lang.String namespaceURI,
                           java.lang.String localName)

setNamedItemNS

public Node setNamedItemNS(Node arg)
                    throws DOMException
DOMException

removeNamedItemNS

public Node removeNamedItemNS(java.lang.String namespaceURI,
                              java.lang.String localName)
                       throws DOMException
DOMException
