Class AttributeMap

java.lang.Object

net.sourceforge.htmlunit.xerces.dom.NamedNodeMapImpl

net.sourceforge.htmlunit.xerces.dom.AttributeMap

All Implemented Interfaces:

NamedNodeMap

public class AttributeMap
extends NamedNodeMapImpl

AttributeMap inherits from NamedNodeMapImpl and extends it to deal with the specifics of storing attributes. These are:

• managing ownership of attribute nodes
• managing default attributes
• firing mutation events

This class doesn't directly support mutation events, however, it notifies the document when mutations are performed so that the document class do so.

Constructor Detail

AttributeMap

protected AttributeMap(ElementImpl ownerNode,
                       NamedNodeMapImpl defaults)

Constructs a named node map.

Parameters:

ownerNode - the owner node

defaults - defaults

Method Detail

setNamedItem

public Node setNamedItem(Node arg)
                  throws DOMException

Adds an attribute using its nodeName attribute.

Specified by:

setNamedItem in interface NamedNodeMap

Overrides:

setNamedItem in class NamedNodeMapImpl

Parameters:

arg - An Attr node to store in this map.

Returns:

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

Throws:

DOMException - The exception description.

See Also:

NamedNodeMap.setNamedItem(org.w3c.dom.Node)

setNamedItemNS

public Node setNamedItemNS(Node arg)
                    throws DOMException

Adds an attribute using its namespaceURI and localName.

Specified by:

setNamedItemNS in interface NamedNodeMap

Overrides:

setNamedItemNS in class NamedNodeMapImpl

Parameters:

arg - A node to store in a named node map.

Returns:

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

Throws:

DOMException

See Also:

NamedNodeMap.setNamedItem(org.w3c.dom.Node)

removeNamedItem

public Node removeNamedItem(String name)
                     throws DOMException

Removes an attribute specified by name.

Specified by:

removeNamedItem in interface NamedNodeMap

Overrides:

removeNamedItem in class NamedNodeMapImpl

Parameters:

name - The name of a node to remove. 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.

Returns:

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

Throws:

DOMException - NOT_FOUND_ERR: Raised if there is no node named name in the map.

removeItem

protected Node removeItem(Node item)
                   throws DOMException

NON-DOM: Remove the node object

NOTE: Specifically removes THIS NODE -- not the node with this name, nor the node with these contents. If node does not belong to this named node map, we throw a DOMException.

Parameters:

item - The node to remove

Returns:

Removed node

Throws:

DOMException - on error

internalRemoveNamedItem

protected final Node internalRemoveNamedItem(String name,
                                             boolean raiseEx)

Internal removeNamedItem method allowing to specify whether an exception must be thrown if the specified name is not found.

Parameters:

name - the mane

raiseEx - if true raise an exception

Returns:

the node

removeNamedItemNS

public Node removeNamedItemNS(String namespaceURI,
                              String name)
                       throws DOMException

Introduced in DOM Level 2.

Removes an attribute specified by local name and namespace URI.

Specified by:

removeNamedItemNS in interface NamedNodeMap

Overrides:

removeNamedItemNS in class NamedNodeMapImpl

Parameters:

namespaceURI - The namespace URI of the node to remove. When it is null or an empty string, this method behaves like removeNamedItem.

name - The local name of the node to remove. If the removed attribute is known to have a default value, an attribute immediately appears containing the default value.

Returns:

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

Throws:

DOMException - NOT_FOUND_ERR: Raised if there is no node named name in the map.

internalRemoveNamedItemNS

protected final Node internalRemoveNamedItemNS(String namespaceURI,
                                               String name,
                                               boolean raiseEx)

Internal removeNamedItemNS method allowing to specify whether an exception must be thrown if the specified local name and namespace URI is not found.

Parameters:

namespaceURI - the namespace uri

name - the name

raiseEx - if true raise exception

Returns:

the node

cloneMap

public NamedNodeMapImpl cloneMap(NodeImpl ownerNode)

Cloning a NamedNodeMap is a DEEP OPERATION; it always clones all the nodes contained in the map.

Overrides:

cloneMap in class NamedNodeMapImpl

Parameters:

ownerNode - the owner node

Returns:

the cloned map

cloneContent

protected void cloneContent(NamedNodeMapImpl srcmap)

Override parent's method to set the ownerNode correctly

Overrides:

cloneContent in class NamedNodeMapImpl

Parameters:

srcmap - the source map

reconcileDefaults

protected void reconcileDefaults(NamedNodeMapImpl defaults)

Get this AttributeMap in sync with the given "defaults" map.

Parameters:

defaults - The default attributes map to sync with.

addItem

protected final int addItem(Node arg)

Overrides:

addItem in class NamedNodeMapImpl
