Constructor Summary

DomNamedNodeMap(Document owner)
Constructs an empty map associated with the specified document.

Method Summary

void	compact() Reduces space utilization for this object.
int	getLength() DOM L1 Returns the length of the map.
Node	getNamedItem(String name) DOM L1 Returns the named item from the map, or null; names are just the nodeName property.
Node	getNamedItemNS(String namespaceURI, String localName) DOM L2 Returns the named item from the map, or null; names are the localName and namespaceURI properties, ignoring any prefix.
boolean	isReadonly() Exposes the internal "readonly" flag.
Node	item(int index) DOM L1 Returns the indexed item from the map, or null.
void	makeReadonly() Sets the internal "readonly" flag so the node and its children can't be changed.
Node	removeNamedItem(String name) DOM L1 Removes the named item from the map, or reports an exception; names are just the nodeName property.
Node	removeNamedItemNS(String namespaceURI, String localName) DOM L2 Removes the named item from the map, or reports an exception; names are the localName and namespaceURI properties.
Node	setNamedItem(Node arg) DOM L1 Stores the named item into the map, optionally overwriting any existing node with that name.
Node	setNamedItemNS(Node arg) DOM L2 Stores the named item into the map, optionally overwriting any existing node with that fully qualified name.

Constructor Detail

DomNamedNodeMap

public DomNamedNodeMap(Document owner)

Constructs an empty map associated with the specified document.

Method Detail

compact

public void compact()

Reduces space utilization for this object.

isReadonly

public final boolean isReadonly()

Exposes the internal "readonly" flag. In DOM, all NamedNodeMap objects found in a DocumentType object are read-only (after they are fully constructed), and those holding attributes of a readonly element will also be readonly.

makeReadonly

public void makeReadonly()

Sets the internal "readonly" flag so the node and its children can't be changed.

getNamedItem

public Node getNamedItem(String name)

DOM L1 Returns the named item from the map, or null; names are just the nodeName property.

Specified by:

getNamedItem in interface NamedNodeMap

getNamedItemNS

public Node getNamedItemNS(String namespaceURI,
                           String localName)

DOM L2 Returns the named item from the map, or null; names are the localName and namespaceURI properties, ignoring any prefix.

Specified by:

getNamedItemNS in interface NamedNodeMap

setNamedItem

public Node setNamedItem(Node arg)

DOM L1 Stores the named item into the map, optionally overwriting any existing node with that name. The name used is just the nodeName attribute.

Specified by:

setNamedItem in interface NamedNodeMap

setNamedItemNS

public Node setNamedItemNS(Node arg)

DOM L2 Stores the named item into the map, optionally overwriting any existing node with that fully qualified name. The name used incorporates the localName and namespaceURI properties, and ignores any prefix.

Specified by:

setNamedItemNS in interface NamedNodeMap

removeNamedItem

public Node removeNamedItem(String name)

DOM L1 Removes the named item from the map, or reports an exception; names are just the nodeName property.

Specified by:

removeNamedItem in interface NamedNodeMap

removeNamedItemNS

public Node removeNamedItemNS(String namespaceURI,
                              String localName)

DOM L2 Removes the named item from the map, or reports an exception; names are the localName and namespaceURI properties.

Specified by:

removeNamedItemNS in interface NamedNodeMap

item

public Node item(int index)

DOM L1 Returns the indexed item from the map, or null.

Specified by:

item in interface NamedNodeMap

getLength

public int getLength()

DOM L1 Returns the length of the map.

Specified by:

getLength in interface NamedNodeMap
