| DTMNamedNodeMap | | public class DTMNamedNodeMap implements NamedNodeMap(Code) | | DTMNamedNodeMap is a quickie (as opposed to quick) implementation of the DOM's
NamedNodeMap interface, intended to support DTMProxy's getAttributes()
call.
Note: this does _not_ current attempt to cache any of the data;
if you ask for attribute 27 and then 28, you'll have to rescan the first
27. It should probably at least keep track of the last one retrieved,
and possibly buffer the whole array.
Also note that there's no fastpath for the by-name query; we search
linearly until we find it or fail to find it. Again, that could be
optimized at some cost in object creation/storage.

| Field Summary | |
| DTM | dtm
The DTM for this node. | | int | element
The DTM element handle. | | short | m_count
The number of nodes in this map. |
| element | | int element(Code) | | The DTM element handle.
|
| m_count | | short m_count(Code) | | The number of nodes in this map.
|
| DTMNamedNodeMap | | public DTMNamedNodeMap(DTM dtm, int element)(Code) | | Create a getAttributes NamedNodeMap for a given DTM element node
Parameters:
dtm - The DTM Reference, must be non-null.
Parameters:
element - The DTM element handle. |
| getLength | | public int getLength()(Code) | | Return the number of Attributes on this Element
The number of nodes in this map. |
| getNamedItem | | public Node getNamedItem(String name)(Code) | | Retrieves a node specified by name.
Parameters:
name - The nodeName of a node to retrieve. A Node (of any type) with the specifiednodeName, or null if it does not identifyany node in this map. |
| getNamedItemNS | | public Node getNamedItemNS(String namespaceURI, String localName)(Code) | | Retrieves a node specified by local name and namespace URI. HTML-only
DOM implementations do not need to implement this method.
Parameters:
namespaceURI - The namespace URI of the node to retrieve.
Parameters:
localName - The local name of the node to retrieve. A Node (of any type) with the specified localname and namespace URI, or null if they do notidentify any node in this map.

DOM Level 2 |
| item | | public Node item(int i)(Code) | | 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:
i - The index of the requested item. The node at the indexth position in the map, ornull if that is not a valid index. |
| removeNamedItem | | public Node removeNamedItem(String name)(Code) | | 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. The node removed from this map if a node with such a nameexists.
exception:
DOMException - NOT_FOUND_ERR: Raised if there is no node named name inthis map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly. |
| removeNamedItemNS | | public Node removeNamedItemNS(String namespaceURI, String localName) throws DOMException(Code) | | 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.
Parameters:
namespaceURI - The namespace URI of the node to remove.
Parameters:
localName - The local name of the node to remove. The node removed from this map if a node with such a localname and namespace URI exists.
exception:
DOMException - NOT_FOUND_ERR: Raised if there is no node with the specifiednamespaceURI and localName in this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.

DOM Level 2 |
| setNamedItem | | public Node setNamedItem(Node newNode)(Code) | | 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:
newNode - node to store in this map. The node will later beaccessible using the value of its nodeName attribute. If the new Node replaces an existing node thereplaced Node is returned, otherwise nullis returned.
exception:
DOMException - WRONG_DOCUMENT_ERR: Raised if arg was created from adifferent document than the one that created this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
INUSE_ATTRIBUTE_ERR: Raised if arg is anAttr that is already an attribute of anotherElement object. The DOM user must explicitly cloneAttr nodes to re-use them in other elements. |
| setNamedItemNS | | public Node setNamedItemNS(Node arg) throws DOMException(Code) | | 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.
Parameters:
arg - A node to store in this map. The node will later beaccessible using the value of its namespaceURI andlocalName attributes. If the new Node replaces an existing node thereplaced Node is returned, otherwise nullis returned.
exception:
DOMException - WRONG_DOCUMENT_ERR: Raised if arg was created from adifferent document than the one that created this map.
NO_MODIFICATION_ALLOWED_ERR: Raised if this map is readonly.
INUSE_ATTRIBUTE_ERR: Raised if arg is anAttr that is already an attribute of anotherElement object. The DOM user must explicitly cloneAttr nodes to re-use them in other elements.
