Class AttributeMap

    java.lang.Object
      org.apache.xerces.dom.NamedNodeMapImpl
          org.apache.xerces.dom.AttributeMap

All Implemented Interfaces:
  java.io.Serializable, org.w3c.dom.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.

Method Detail

### setNamedItem

    public org.w3c.dom.Node setNamedItem(org.w3c.dom.Node arg)
                                  throws org.w3c.dom.DOMException

  Adds an attribute using its nodeName attribute.

  Specified by:
    `setNamedItem` in interface `org.w3c.dom.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:
    `org.w3c.dom.DOMException` - The exception description.
  See Also:
    `NamedNodeMap.setNamedItem(org.w3c.dom.Node)`

### setNamedItemNS

    public org.w3c.dom.Node setNamedItemNS(org.w3c.dom.Node arg)
                                    throws org.w3c.dom.DOMException

  Adds an attribute using its namespaceURI and localName.

  Specified by:
    `setNamedItemNS` in interface `org.w3c.dom.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:
    `org.w3c.dom.DOMException`
  See Also:
    `NamedNodeMap.setNamedItem(org.w3c.dom.Node)`

### removeNamedItem

    public org.w3c.dom.Node removeNamedItem(java.lang.String name)
                                     throws org.w3c.dom.DOMException

  Specified by:
    `removeNamedItem` in interface `org.w3c.dom.NamedNodeMap`
  Overrides:
    `removeNamedItem` in class `NamedNodeMapImpl`
  Throws:
    `org.w3c.dom.DOMException`

### removeItem

    protected org.w3c.dom.Node removeItem(org.w3c.dom.Node item,
                                          boolean addDefault)
                                   throws org.w3c.dom.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
    `addDefault` - true -- magically add default attribute
  Returns:
    Removed node
  Throws:
    `org.w3c.dom.DOMException`

### internalRemoveNamedItem

    protected final org.w3c.dom.Node internalRemoveNamedItem(java.lang.String name,
                                                             boolean raiseEx)

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

### removeNamedItemNS

    public org.w3c.dom.Node removeNamedItemNS(java.lang.String namespaceURI,
                                              java.lang.String name)
                                       throws org.w3c.dom.DOMException

  Introduced in DOM Level 2.

  Removes an attribute specified by local name and namespace URI.

  Specified by:
    `removeNamedItemNS` in interface `org.w3c.dom.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:
    `NOT_FOUND_ERR:` - Raised if there is no node named name in the map.
    `org.w3c.dom.DOMException`

### internalRemoveNamedItemNS

### cloneMap
