All Implemented Interfaces:

Cloneable, Element, EventTarget, Node, NodeList, TypeInfo

Direct Known Subclasses:

ElementNSImpl
```
public class ElementImpl
extends ParentNode
implements Element, TypeInfo
```
Elements represent most of the "markup" and structure of the document. They contain both the data for the element itself (element name and attributes), and any contained nodes, including document text (as children).
Elements may have Attributes associated with them; the API for this is defined in Node, but the function is implemented here. In general, XML applications should retrive Attributes as Nodes, since they may contain entity references and hence be a fairly complex sub-tree. HTML users will be dealing with simple string values, and convenience methods are provided to work in terms of Strings.
ElementImpl does not support Namespaces. ElementNSImpl, which inherits from it, does.

  - cloneNode
```
public Node cloneNode(boolean deep)
```
    Returns a duplicate of a given node. You can consider this a generic "copy constructor" for nodes. The newly returned object should be completely independent of the source object's subtree, so changes in one after the clone has been made will not affect the other.
    Note: since we never have any children deep is meaningless here, ParentNode overrides this behavior. Returns a duplicate of a given node.

The newly returned object should be completely independent of the source object's subtree, so changes in one after the clone has been made will not affect the other.
    Note: since we never have any children deep is meaningless here, ParentNode overrides this behavior. Returns a duplicate of a given node. You can consider this a generic "copy constructor" for nodes. The newly returned object should be completely independent of the source object's subtree, so changes in one after the clone has been made will not affect the other.
    Example: Cloning a Text node will copy both the node and the text it contains.
    Example: Cloning something that has children -- Element or Attr, for example -- will _not_ clone those children unless a "deep clone" has been requested. A shallow clone of an Attr node will yield an empty Attr of the same name.
    NOTE: Clones will always be read/write, even if the node being cloned is read-only, to permit applications using only the DOM API to obtain editable copies of locked portions of the tree. Return a duplicate copy of this Element. Note that its children will not be copied unless the "deep" flag is true, but Attributes are always replicated.

  - getBaseURI
```
public String getBaseURI()
```
    The absolute base URI of this node or null if undefined. This value is computed according to . However, when the Document supports the feature "HTML" , the base URI is computed using first the value of the href attribute of the HTML BASE element if any, and the value of the documentURI attribute from the Document interface otherwise.
    When the node is an Element, a Document or a a ProcessingInstruction, this attribute represents the properties [base URI] defined in . When the node is a Notation, an Entity, or an EntityReference, this attribute represents the properties [declaration base URI] in the . How will this be affected by resolution of relative namespace URIs issue?It's not.Should this only be on Document, Element, ProcessingInstruction, Entity, and Notation nodes, according to the infoset? If not, what is it equal to on other nodes? Null? An empty string? I think it should be the parent's.No.Should this be read-only and computed or and actual read-write attribute?Read-only and computed (F2F 19 Jun 2000 and teleconference 30 May 2001).If the base HTML element is not yet attached to a document, does the insert change the Document.baseURI?

public String getAttribute(String name)
```
    Look up a single Attribute by name. Returns the Attribute's string value, or an empty string (NOT null!) to indicate that the name did not map to a currently defined attribute.
    Note: Attributes may contain complex node trees. This method returns the "flattened" string obtained from Attribute.getValue(). If you need the structure information, see getAttributeNode().

```
public Attr getAttributeNode(String name)
```
    Look up a single Attribute by name. Returns the Attribute Node, so its complete child tree is available. This could be important in XML, where the string rendering may not be sufficient information.
    If no matching attribute is available, returns null.
    
    Specified by:

  - getElementsByTagName
```
public NodeList getElementsByTagName(String tagname)
```
    Returns a NodeList of all descendent nodes (children, grandchildren, and so on) which are Elements and which have the specified tag name.
    Note: NodeList is a "live" view of the DOM. Its contents will change as the DOM changes, and alterations made to the NodeList will be reflected in the DOM.
    
    Specified by:
    
    getElementsByTagName in interface Element
    
    Parameters:
    
    tagname - The type of element to gather. To obtain a list of all elements no matter what their names, use the wild-card tag name "*".

  - getTagName
```
public String getTagName()
```
    Returns the name of the Element. Note that Element.nodeName() is defined to also return the tag name.
    This is case-preserving in XML. HTML should uppercasify it on the way in.
    
    Specified by:
    
    getTagName in interface Element
  - removeAttribute
```
public void removeAttribute(String name)
```
    Remove the named attribute from this Element. If the removed Attribute has a default value, it is immediately replaced thereby.
    The default logic is actually implemented in NamedNodeMapImpl. PR-DOM-Level-1-19980818 doesn't fully address the DTD, so some of this behavior is likely to change in future versions. ?????
    Note that this call "succeeds" even if no attribute by this name existed -- unlike removeAttributeNode, which will throw a not-found exception in that case.
    
    Specified by:
    
    removeAttribute in interface Element
    
    Throws:
    
    DOMException - NO_MODIFICATION_ALLOWED_ERR if the node is readonly.
  - removeAttributeNode
```
public Attr removeAttributeNode(Attr oldAttr)
                         throws DOMException
```
    Remove the specified attribute/value pair. If the removed Attribute has a default value, it is immediately replaced.
    NOTE: Specifically removes THIS NODE -- not the node with this name, nor the node with these contents. If the specific Attribute object passed in is not stored in this Element, we throw a DOMException. If you really want to remove an attribute by name, use removeAttribute().
    
    Specified by:
    
    removeAttributeNode in interface Element
    
    Returns:
    
    the Attribute object that was removed.
    
    Throws:
    
    DOMException - NOT_FOUND_ERR if oldattr is not an attribute of this Element.
    
    DOMException - NO_MODIFICATION_ALLOWED_ERR if the node is readonly.
  - setAttribute
```
public void setAttribute(String name,
                         String value)
```
    Add a new name/value pair, or replace the value of the existing attribute having that name.
    Note: this method supports only the simplest kind of Attribute, one whose value is a string contained in a single Text node. If you want to assert a more complex value (which XML permits, though HTML doesn't), see setAttributeNode().
    The attribute is created with specified=true, meaning it's an explicit value rather than inherited from the DTD as a default. Again, setAttributeNode can be used to achieve other results.
    
    Specified by:
    
    setAttribute in interface Element
    
    Throws:
    
    DOMException - INVALID_NAME_ERR if the name is not acceptable. (Attribute factory will do that test for us.)
    
    DOMException - NO_MODIFICATION_ALLOWED_ERR if the node is readonly.
  - setAttributeNode
```
public Attr setAttributeNode(Attr newAttr)
                      throws DOMException
```
    Add a new attribute/value pair, or replace the value of the existing attribute with that name.
    This method allows you to add an Attribute that has already been constructed, and hence avoids the limitations of the simple setAttribute() call. It can handle attribute values that have arbitrarily complex tree structure -- in particular, those which had entity references mixed into their text.
    
    Specified by:
    
    setAttributeNode in interface Element
    
    Throws:
    
    DOMException - INUSE_ATTRIBUTE_ERR if the Attribute object has already been assigned to another Element.
  - getAttributeNS
```
public String getAttributeNS(String namespaceURI,
                             String localName)
```
    Introduced in DOM Level 2.
    Retrieves an attribute value by local name and namespace URI.
    
    Specified by:
    
    getAttributeNS in interface Element
    
    Parameters:
    
    namespaceURI - The namespace URI of the attribute to retrieve.
    
    localName - The local name of the attribute to retrieve.
    
    Returns:
    
    String The Attr value as a string, or empty string if that attribute does not have a specified or default value.
  - setAttributeNS
```
public void setAttributeNS(String namespaceURI,
                           String qualifiedName,
                           String value)
```
    Introduced in DOM Level 2.
    Adds a new attribute. If the given namespaceURI is null or an empty string and the qualifiedName has a prefix that is "xml", the new attribute is bound to the predefined namespace "http://www.w3.org/XML/1998/namespace" [Namespaces]. If an attribute with the same local name and namespace URI is already present on the element, its prefix is changed to be the prefix part of the qualifiedName, and its value is changed to be the value parameter. This value is a simple string, it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNodeNS or setAttributeNode to assign it as the value of an attribute.
    
    Specified by:
    
    setAttributeNS in interface Element
    
    Parameters:
    
    namespaceURI - The namespace URI of the attribute to create or alter.
    
    qualifiedName - The qualified name of the attribute to create or alter.
    
    value - The value to set in string form.
  - removeAttributeNS
```
public void removeAttributeNS(String namespaceURI,
                              String localName)
```
    Introduced in DOM Level 2.
    Removes an attribute by local name and namespace URI. If the removed attribute has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix.
    
    Specified by:
    
    removeAttributeNS in interface Element
    
    Parameters:
    
    namespaceURI - The namespace URI of the attribute to remove.
    
    localName - The local name of the attribute to remove.
  - getAttributeNodeNS
```
public Attr getAttributeNodeNS(String namespaceURI,
                               String localName)
```
    Retrieves an Attr node by local name and namespace URI.
    
    Specified by:
    
    getAttributeNodeNS in interface Element
    
    Parameters:
    
    namespaceURI - The namespace URI of the attribute to retrieve.
    
    localName - The local name of the attribute to retrieve.
    
    Returns:
    
    Attr The Attr node with the specified attribute local name and namespace URI or null if there is no such attribute.
  - setAttributeNodeNS
```
public Attr setAttributeNodeNS(Attr newAttr)
                        throws DOMException
```
    Introduced in DOM Level 2.
    Adds a new attribute. If an attribute with that local name and namespace URI is already present in the element, it is replaced by the new one.
    
    Specified by:
    
    setAttributeNodeNS in interface Element
    
    Parameters:
    
    newAttr - The Attr node to add to the attribute list. When the Node has no namespaceURI, this method behaves like setAttributeNode.
    
    Returns:
    
    Attr If the newAttr attribute replaces an existing attribute with the same local name and namespace URI, the * previously existing Attr node is returned, otherwise null is returned.
    
    Throws:
    
    DOMException - WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
    
    DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
    
    DOMException - INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.
  - hasAttributes

    Introduced in DOM Level 2.
    Returns a NodeList of all the Elements with a given local name and namespace URI in the order in which they would be encountered in a preorder traversal of the Document tree, starting from this node.
    
    Specified by:
    
    getElementsByTagNameNS in interface Element
    
    Parameters:
    
    namespaceURI - The namespace URI of the elements to match on. The special value "*" matches all namespaces. When it is null or an empty string, this method behaves like getElementsByTagName.
    
    localName - The local name of the elements to match on. The special value "*" matches all local names.
    
    Returns:
    
    NodeList A new NodeList object containing all the matched Elements.
  - isEqualNode
```
public boolean isEqualNode(Node arg)
```
    Tests whether two nodes are equal.
    This method tests for equality of nodes, not sameness (i.e., whether the two nodes are references to the same object) which can be tested with Node.isSameNode. All nodes that are the same will also be equal, though the reverse may not be true.
    Two nodes are equal if and only if the following conditions are satisfied: The two nodes are of the same type.The following string attributes are equal: nodeName, localName, namespaceURI, prefix, nodeValue , baseURI. This is: they are both null, or they have the same length and are character for character identical. The attributes NamedNodeMaps are equal. This is: they are both null, or they have the same length and for each node that exists in one map there is a node that exists in the other map and is equal, although not necessarily at the same index.The childNodes NodeLists are equal. This is: they are both null, or they have the same length and contain equal nodes at the same index. This is true for Attr nodes as for any other type of node. Note that normalization can affect equality; to avoid this, nodes should be normalized before being compared.
    For two DocumentType nodes to be equal, the following conditions must also be satisfied: The following string attributes are equal: publicId, systemId, internalSubset.The entities NamedNodeMaps are equal.The notations NamedNodeMaps are equal.
    On the other hand, the following do not affect equality: the ownerDocument attribute, the specified attribute for Attr nodes, the isWhitespaceInElementContent attribute for Text nodes, as well as any user data or event listeners registered on the nodes. DOM Level 3 WD- Experimental. Override inherited behavior from NodeImpl to support deep equal. DOM Level 3 WD- Experimental.

```
    Introduced in DOM Level 3.
    Checks if a type is derived from another by restriction. See: http://www.w3.org/TR/DOM-Level-3-Core/core.html#TypeInfo-isDerivedFrom
    
    Specified by:
    
    isDerivedFrom in interface TypeInfo
    
    Parameters:
    
    typeNamespaceArg - The namspace of the ancestor type declaration
    
    typeNameArg - The name of the ancestor type declaration
    
    derivationMethod - The derivation method
    
    Returns:
    
    boolean True if the type is derived by restriciton for the reference type
  - getSchemaTypeInfo
```
public TypeInfo getSchemaTypeInfo()
```
    Method getSchemaTypeInfo.
    
    Specified by:
    
    getSchemaTypeInfo in interface Element
    
    Returns:
    
    TypeInfo
  - setReadOnly
```
public void setReadOnly(boolean readOnly,
                        boolean deep)
```
    NON-DOM: PR-DOM-Level-1-19980818 mentions readonly nodes in conjunction with Entities, but provides no API to support this.
    Most DOM users should not touch this method. Its anticpated use is during construction of EntityRefernces, where it will be used to lock the contents replicated from Entity so they can't be casually altered. It _could_ be published as a DOM extension, if desired.
    Note: since we never have any children deep is meaningless here, ParentNode overrides this behavior. Override default behavior so that if deep is true, children are also toggled. NON-DOM: Subclassed to flip the attributes' readonly switch as well.
    
    Overrides:
    
    setReadOnly in class ParentNode
    
    Parameters:
    
    readOnly - True or false as desired.
    
    deep - If true, children are also toggled. Note that this will not change the state of an EntityReference or its children, which are always read-only.

    NodeImpl.setReadOnly(boolean, boolean)
  - synchronizeData
```
protected void synchronizeData()
```
    Override this method in subclass to hook in efficient internal data structure. Synchronizes the data (name and value) for fast nodes.
    
    Overrides:
    
    synchronizeData in class NodeImpl
  - setupDefaultAttributes
```
protected void setupDefaultAttributes()
```
    Setup the default attributes.
  - reconcileDefaultAttributes
```
protected void reconcileDefaultAttributes()
```
    Reconcile default attributes.
  - getDefaultAttributes
```
protected NamedNodeMapImpl getDefaultAttributes()
```
  - getChildElementCount
```
public final int getChildElementCount()
