NodeImpl

public NodeImpl()

empty constructor

NodeImpl

public NodeImpl(CharacterData text)

constructor which adopts the name and NS of the char data, and its text

Parameters:

text -

appendChild

public Node appendChild(Node newChild)
            throws DOMException

Adds the node newChild to the end of the list of children of this node. If the newChild is already in the tree, it is first removed.

Parameters:

newChild - The node to add.If it is a DocumentFragment object, the entire contents of the document fragment are moved into the child list of this node

Returns:

The node added.

cloneNode

public Node cloneNode(boolean deep)

Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent; ( parentNode is null.).
Cloning an Element copies all attributes and their values, including those generated by the XML processor to represent defaulted attributes, but this method does not copy any text it contains unless it is a deep clone, since the text is contained in a child Text node. Cloning an Attribute directly, as opposed to be cloned as part of an Element cloning operation, returns a specified attribute ( specified is true). Cloning any other type of node simply returns a copy of this node.
Note that cloning an immutable subtree results in a mutable copy, but the children of an EntityReference clone are readonly . In addition, clones of unspecified Attr nodes are specified. And, cloning Document, DocumentType, Entity, and Notation nodes is implementation dependent.

Parameters:

deep - If true, recursively clone the subtree under the specified node; if false, clone only the node itself (and its attributes, if it is an Element).

Returns:

The duplicate node.

compareDocumentPosition

public short compareDocumentPosition(Node other)

convertAttrSAXtoDOM

protected NamedNodeMap convertAttrSAXtoDOM(Attributes saxAttr)

The internal representation of Attributes cannot help being changed It is because Attribute is not immutible Type, so if we keep out value and just return it in another form, the application may chnae it, which we cannot detect without some kind back track method (call back notifying the chnage.) I am not sure which approach is better.

getAttributes

public NamedNodeMap getAttributes()

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

getBaseURI

public String getBaseURI()

getChildNodes

public NodeList getChildNodes()

A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes.

getFeature

public Object getFeature(String feature,
                         String version)

getFirstChild

public Node getFirstChild()

The first child of this node. If there is no such node, this returns null.

getLastChild

public Node getLastChild()

The last child of this node. If there is no such node, this returns null.

getLocalName

public String getLocalName()

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.

Since:

DOM Level 2

getNamespaceURI

public String getNamespaceURI()

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.

Since:

DOM Level 2

getNextSibling

public Node getNextSibling()

The node immediately following this node. If there is no such node, this returns null.

getNodeName

public String getNodeName()

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

getNodeType

public short getNodeType()

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

getNodeValue

public String getNodeValue()
            throws DOMException

The value of this node, depending on its type; see the table above. When it is defined to be null, setting it has no effect.

getOwnerDocument

public Document getOwnerDocument()

The Document object associated with this node. This is also the Document object used to create new nodes. When this node is a Document or a DocumentType which is not used with any Document yet, this is null.

getParentNode

public Node getParentNode()

The parent of this node. All nodes, except Attr, Document, DocumentFragment, Entity, and Notation may have a parent. However, if a node has just been created and not yet added to the tree, or if it has been removed from the tree, this is null.

getPrefix

public String getPrefix()

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.

Since:

DOM Level 2

getPreviousSibling

public Node getPreviousSibling()

The node immediately preceding this node. If there is no such node, this returns null.

getSchemaTypeInfo

public TypeInfo getSchemaTypeInfo()

getTextContent

public String getTextContent()

getUserData

public Object getUserData(String key)

hasAttributes

public boolean hasAttributes()

Returns whether this node (if it is an element) has any attributes.

Returns:

true if this node has any attributes, false otherwise.

Since:

DOM Level 2

hasChildNodes

public boolean hasChildNodes()

Returns whether this node has any children.

Returns:

true if this node has any children, false otherwise.

initializeChildren

protected void initializeChildren()

Initialize the children array

insertBefore

public Node insertBefore(Node newChild,
                         Node refChild)
            throws DOMException

Inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children.
If newChild is a DocumentFragment object, all of its children are inserted, in the same order, before refChild. If the newChild is already in the tree, it is first removed.

Parameters:

newChild - The node to insert.

refChild - The reference node, i.e., the node before which the new node must be inserted.

Returns:

The node being inserted.

isDefaultNamespace

public boolean isDefaultNamespace(String namespaceURI)

isDirty

public boolean isDirty()

get the dirty bit

Returns:

isEqualNode

public boolean isEqualNode(Node arg)

isSameNode

public boolean isSameNode(Node other)

isSupported

public boolean isSupported(String feature,
                           String version)

Tests whether the DOM implementation implements a specific feature and that feature is supported by this node.

Parameters:

feature - The name of the feature to test. This is the same name which can be passed to the method hasFeature on DOMImplementation.

version - This is the version number of the feature to test. In Level 2, version 1, this is the string "2.0". If the version is not specified, supporting any version of the feature will cause the method to return true.

Returns:

Returns true if the specified feature is supported on this node, false otherwise.

Since:

DOM Level 2

lookupNamespaceURI

public String lookupNamespaceURI(String prefix)

lookupPrefix

public String lookupPrefix(String namespaceURI)

makeAttributesEditable

protected AttributesImpl makeAttributesEditable()

make the attributes editable

Returns:

AttributesImpl

normalize

public void normalize()

Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes. This can be used to ensure that the DOM view of a document is the same as if it were saved and re-loaded, and is useful when operations (such as XPointer lookups) that depend on a particular document tree structure are to be used.In cases where the document contains CDATASections, the normalize operation alone may not be sufficient, since XPointers do not differentiate between Text nodes and CDATASection nodes.

removeChild

public Node removeChild(Node oldChild)
            throws DOMException

Removes the child node indicated by oldChild from the list of children, and returns it.

Parameters:

oldChild - The node being removed.

Returns:

The node removed.

replaceChild

public Node replaceChild(Node newChild,
                         Node oldChild)
            throws DOMException

Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.
If newChild is a DocumentFragment object, oldChild is replaced by all of the DocumentFragment children, which are inserted in the same order. If the newChild is already in the tree, it is first removed.

Parameters:

newChild - The new node to put in the child list.

oldChild - The node being replaced in the list.

Returns:

The node replaced.

setPrefix

public void setPrefix(String prefix)

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.
