java.lang.Objectorg.kde.koala.NamedNodeMap
public class NamedNodeMap
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
ArrayList
; NamedNodeMap
s 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.

public Node getNamedItem(java.lang.String name)
name
- Name of a node to retrieve.
Node
(of any type) with the specified
name, or null
if the specified name did not
identify any node in the map.public Node setNamedItem(Node arg)
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.
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.
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.
Node
replaces an existing
node with the same name the previously existing Node
is returned, otherwise null
is returned.public Node removeNamedItem(java.lang.String name)
Attr
with a default value it is immediately
replaced.
name
- The name of a node to remove.
null
if
no node with such a name exists.public Node item(long index)
index
th item in the map. If
index
is greater than or equal to the number of nodes
in the map, this returns null
.
index
- Index into the map.
index
th position in the
NamedNodeMap
, or null
if that is
not a valid index.public Node getNamedItemNS(java.lang.String namespaceURI, java.lang.String localName)
namespaceURI
- The namespace URI of the node to retrieve.localName
- The local name of the node to retrieve.
public Node setNamedItemNS(Node arg)
arg
- A node to store in this map. The node will later be
accessible using the value of its namespaceURI and localName attributes.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map 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.
public Node removeNamedItemNS(java.lang.String namespaceURI, java.lang.String localName)
namespaceURI
- The namespace URI of the node to remove.localName
- The local name of the node to remove.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
