                   int id)

Method Detail

afterClone

protected void afterClone(boolean deep)

Description copied from class: DNode

This method is meant to be after the Object.clone() call. This method will clone the attribute list, and if the deep flag is true, this method will clone all child nodes of the original object, and add them to the clone.

Overrides:

afterClone in class DNode

Parameters:

deep - True if the node is intended to be a deep child copy

onDAttrValueChange

protected void onDAttrValueChange(DAttr attr)

Overrides:

onDAttrValueChange in class DNode

getAttribute

public final String getAttribute(int attrNameId)

setAttribute

protected void setAttribute(int attrNameId,
                            String value)

getNodeType

public short getNodeType()

Description copied from interface: Node

A code representing the type of the underlying object, as defined above.

Specified by:

getNodeType in interface Node

Overrides:

getNodeType in class DNode

getNodeName

public String getNodeName()

Description copied from interface: Node

The name of this node, depending on its type; see the table above.

Specified by:

getNodeName in interface Node

Overrides:

getNodeName in class DNode

getTagName

public String getTagName()

Description copied from interface: Element

The name of the element. For example, in:

 <elementExample 
 id="demo"> ... </elementExample> , 

tagName has the value "elementExample". Note that this is case-preserving in XML, as are all of the operations of the DOM. The HTML DOM returns the tagName of an HTML element in the canonical uppercase form, regardless of the case in the source HTML document.

Specified by:

getTagName in interface Element

attrNameToId

protected int attrNameToId(String name)

Overrides:

attrNameToId in class DNode

getAttribute

public String getAttribute(String name)

Description copied from interface: Element

Retrieves an attribute value by name.

Specified by:

getAttribute in interface Element

Returns:

The Attr value as a string, or the empty string if that attribute does not have a specified or default value.

setAttribute

public void setAttribute(String name,
                         String value)

Description copied from interface: Element

Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of 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 setAttributeNode to assign it as the value of an attribute.
To set an attribute with a qualified name and namespace URI, use the setAttributeNS method.

Specified by:

setAttribute in interface Element

removeAttribute

public void removeAttribute(String name)

Description copied from interface: Element

Removes an attribute by name. 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.
To remove an attribute by local name and namespace URI, use the removeAttributeNS method.

Specified by:

removeAttribute in interface Element

getAttributeNode

public Attr getAttributeNode(String name)

Description copied from interface: Element

Retrieves an attribute node by name.
To retrieve an attribute node by qualified name and namespace URI, use the getAttributeNodeNS method.

Specified by:

getAttributeNode in interface Element

Returns:

The Attr node with the specified name ( nodeName) or null if there is no such attribute.

setAttributeNode

public Attr setAttributeNode(Attr newAttr)

Description copied from interface: Element

Adds a new attribute node. If an attribute with that name ( nodeName) is already present in the element, it is replaced by the new one.
To add a new attribute node with a qualified name and namespace URI, use the setAttributeNodeNS method.

Specified by:

setAttributeNode in interface Element

Returns:

If the newAttr attribute replaces an existing attribute, the replaced Attr node is returned, otherwise null is returned.

removeAttributeNode

public Attr removeAttributeNode(Attr oldAttr)

Description copied from interface: Element

Removes the specified attribute node. If the removed Attr 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, when applicable.

Specified by:

removeAttributeNode in interface Element

Returns:

The Attr node that was removed.

getElementsByTagName

public NodeList getElementsByTagName(String name)

Description copied from interface: Element

Returns a NodeList of all descendant Elements with a given tag name, in the order in which they are encountered in a preorder traversal of this Element tree.

Specified by:

getElementsByTagName in interface Element

Returns:

A list of matching Element nodes.

getAttributes

public NamedNodeMap getAttributes()

Description copied from interface: Node

A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.

Specified by:

getAttributes in interface Node

Overrides:

getAttributes in class DNode

getLocalName

public String getLocalName()

Description copied from interface: Node

Returns the local part of the qualified name of this node.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Specified by:

getLocalName in interface Node

Overrides:

getLocalName in class DNode

getPrefix

public String getPrefix()

Description copied from interface: Node

The namespace prefix of this node, or null if it is unspecified.
Note that setting this attribute, when permitted, changes the nodeName attribute, which holds the qualified name, as well as the tagName and name attributes of the Element and Attr interfaces, when applicable.
Note also that changing the prefix of an attribute that is known to have a default value, does not make a new attribute with the default value and the original prefix appear, since the namespaceURI and localName do not change.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.

Specified by:

getPrefix in interface Node

Overrides:

getPrefix in class DNode

getNamespaceURI

public String getNamespaceURI()

Description copied from interface: Node

The namespace URI of this node, or null if it is unspecified.
This is not a computed value that is the result of a namespace lookup based on an examination of the namespace declarations in scope. It is merely the namespace URI given at creation time.
For nodes of any type other than ELEMENT_NODE and ATTRIBUTE_NODE and nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is always null.Per the Namespaces in XML Specification an attribute does not inherit its namespace from the element it is attached to. If an attribute is not explicitly given a namespace, it simply has no namespace.

Specified by:

getNamespaceURI in interface Node

Overrides:

getNamespaceURI in class DNode

setAttributeNS

public void setAttributeNS(String namespaceURI,
                           String qualifiedName,
                           String value)

Description copied from interface: Element

Adds a new attribute. 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.
