Method Detail

getLength

public int getLength()

Description copied from interface: NamedNodeMap

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

Specified by:

getLength in interface NamedNodeMap

getNamedItem

public Node getNamedItem(java.lang.String name)

Description copied from interface: NamedNodeMap

Retrieves a node specified by name.

Specified by:

getNamedItem in interface NamedNodeMap

Returns:

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

setNamedItem

public Node setNamedItem(Node node)

Description copied from interface: NamedNodeMap

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.

Specified by:

setNamedItem in interface NamedNodeMap

Returns:

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

removeNamedItem

public Node removeNamedItem(java.lang.String name)

Description copied from interface: NamedNodeMap

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.

Specified by:

removeNamedItem in interface NamedNodeMap

Returns:

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

getNamedItemNS

public Node getNamedItemNS(java.lang.String nsURI,
                           java.lang.String name)

Description copied from interface: NamedNodeMap

Retrieves a node specified by local name and namespace URI. HTML-only DOM implementations do not need to implement this method.

Specified by:

getNamedItemNS in interface NamedNodeMap

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.

setNamedItemNS

public Node setNamedItemNS(Node node)

Description copied from interface: NamedNodeMap

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.

Specified by:

setNamedItemNS in interface NamedNodeMap

Returns:

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

removeNamedItemNS

public Node removeNamedItemNS(java.lang.String nsURI,
                              java.lang.String name)

Description copied from interface: NamedNodeMap

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.

Specified by:

removeNamedItemNS in interface NamedNodeMap

Returns:

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

item

public Node item(int index)

Description copied from interface: NamedNodeMap

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.

Specified by:

item in interface NamedNodeMap

Returns:

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