public abstract class NodeImpl
extends Object
implements Node, NodeList, EventTarget, Cloneable, Serializable

NodeImpl provides the basic structure of a DOM tree. It is never used directly, but instead is subclassed to add type and data information, and additional methods, appropriate to each node of the tree. Only its subclasses should be instantiated -- and those, with the exception of Document itself, only through a specific Document's factory methods.

The Node interface provides shared behaviors such as siblings and children, both for consistancy and so that the most common tree operations may be performed without constantly having to downcast to specific node types. When there is no obvious mapping for one of these queries, it will respond with null. Note that the default behavior is that children are forbidden. To permit them, the subclass ParentNode overrides several methods.

NodeImpl also implements NodeList, so it can return itself in response to the getChildNodes() query. This eliminiates the need for a separate ChildNodeList object. Note that this is an IMPLEMENTATION DETAIL; applications should _never_ assume that this identity exists.

All nodes in a single document must originate in that document. (Note that this is much tighter than "must be same implementation") Nodes are all aware of their ownerDocument, and attempts to mismatch will throw WRONG_DOCUMENT_ERR.

However, to save memory not all nodes always have a direct reference to their ownerDocument. When a node is owned by another node it relies on its owner to store its ownerDocument. Parent nodes always store it though, so there is never more than one level of indirection. And when a node doesn't have an owner, ownerNode refers to its ownerDocument.

This class doesn't directly support mutation events, however, it still implements the EventTarget interface and forward all related calls to the document so that the document class do so.

Constructor Detail

NodeImpl

protected NodeImpl(CoreDocumentImpl ownerDocument)
No public constructor; only subclasses of Node should be instantiated, and those normally via a Document's factory methods

Every Node knows what Document it belongs to.


NodeImpl

public NodeImpl()
Constructor for serialization.
Method Detail

getNodeType

public abstract short getNodeType()
A short integer indicating what type of node this is. The named constants for this value are defined in the org.w3c.dom.Node interface.
Specified by:
getNodeType in interface Node

getNodeName

public abstract String getNodeName()
the name of this node.
Specified by:
getNodeName in interface Node

getNodeValue

public String getNodeValue()
Returns the node value.
Specified by:
getNodeValue in interface Node

setNodeValue

public void setNodeValue(String x)
                  throws DOMException
Sets the node value.
Specified by:
setNodeValue in interface Node
Throws:
DOMException(NO_MODIFICATION_ALLOWED_ERR) -  

appendChild

public Node appendChild(Node newChild)
                 throws DOMException
Adds a child node to the end of the list of children for this node. Convenience shorthand for insertBefore(newChild,null).
Specified by:
appendChild in interface Node
Throws:
DOMException(HIERARCHY_REQUEST_ERR) - if newChild is of a type that shouldn't be a child of this node.
DOMException(WRONG_DOCUMENT_ERR) - if newChild has a different owner document than we do.
DOMException(NO_MODIFICATION_ALLOWED_ERR) - if this node is read-only.

By default we do not accept any children, ParentNode overrides this., ParentNode


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.

Specified by:
cloneNode in interface Node
See Also:

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.


getOwnerDocument

public Document getOwnerDocument()
Find the Document that this Node belongs to (the document in whose context the Node was created). The Node may or may not currently be part of that Document's actual contents.
Specified by:
getOwnerDocument in interface Node

ownerDocument

CoreDocumentImpl ownerDocument()
same as above but returns internal type and this one is not overridden by CoreDocumentImpl to return null

setOwnerDocument

void setOwnerDocument(CoreDocumentImpl doc)
NON-DOM set the ownerDocument of this node

getParentNode

public Node getParentNode()
Obtain the DOM-tree parent of this node, or null if it is not currently active in the DOM tree (perhaps because it has just been created or removed). Note that Document, DocumentFragment, and Attribute will never have parents.
Specified by:
getParentNode in interface Node

parentNode

NodeImpl parentNode()

getNextSibling

public Node getNextSibling()
The next child of this node's parent, or null if none
Specified by:
getNextSibling in interface Node

getPreviousSibling

public Node getPreviousSibling()
The previous child of this node's parent, or null if none
Specified by:
getPreviousSibling in interface Node

previousSibling

ChildNode previousSibling()

getAttributes

public NamedNodeMap getAttributes()
Return the collection of attributes associated with this node, or null if none. At this writing, Element is the only type of node which will ever have attributes.
Specified by:
getAttributes in interface Node
See Also:
ElementImpl

hasAttributes

public boolean hasAttributes()
Returns whether this node (if it is an element) has any attributes.
Specified by:
hasAttributes in interface Node
Returns:
true if this node has any attributes, false otherwise.
Since:
DOM Level 2
See Also:
ElementImpl

hasChildNodes

public boolean hasChildNodes()
Test whether this node has any children. Convenience shorthand for (Node.getFirstChild()!=null)

By default we do not have any children, ParentNode overrides this.

Specified by:
hasChildNodes in interface Node
See Also:
ParentNode

getChildNodes

public NodeList getChildNodes()
Obtain a NodeList enumerating all children of this node. If there are none, an (initially) empty NodeList is returned.

NodeLists are "live"; as children are added/removed the NodeList will immediately reflect those changes. Also, the NodeList refers to the actual nodes, so changes to those nodes made via the DOM tree will be reflected in the NodeList and vice versa.

In this implementation, Nodes implement the NodeList interface and provide their own getChildNodes() support. Other DOMs may solve this differently.

Specified by:
getChildNodes in interface Node

getFirstChild

public Node getFirstChild()
The first child of this Node, or null if none.

By default we do not have any children, ParentNode overrides this.

Specified by:
getFirstChild in interface Node
See Also:
ParentNode

getLastChild

public Node getLastChild()
The first child of this Node, or null if none.

By default we do not have any children, ParentNode overrides this.

Specified by:
getLastChild in interface Node
See Also:
ParentNode

insertBefore

public Node insertBefore(Node newChild,
                         Node refChild)
                  throws DOMException
Move one or more node(s) to our list of children. Note that this implicitly removes them from their previous parent.

By default we do not accept any children, ParentNode overrides this.

Specified by:
insertBefore in interface Node
Parameters:
newChild - The Node to be moved to our subtree. As a convenience feature, inserting a DocumentNode will instead insert all its children.
refChild - Current child which newChild should be placed immediately before. If refChild is null, the insertion occurs after all existing Nodes, like appendChild().
Throws:
DOMException(HIERARCHY_REQUEST_ERR) - if newChild is of a type that shouldn't be a child of this node, or if newChild is an ancestor of this node.
DOMException(WRONG_DOCUMENT_ERR) - if newChild has a different owner document than we do.
DOMException(NOT_FOUND_ERR) - if refChild is not a child of this node.
DOMException(NO_MODIFICATION_ALLOWED_ERR) - if this node is read-only.
See Also:
ParentNode

removeChild

public Node removeChild(Node oldChild)
                 throws DOMException
Remove a child from this Node. The removed child's subtree remains intact so it may be re-inserted elsewhere.

By default we do not have any children, ParentNode overrides this.

Specified by:
removeChild in interface Node
Returns:
oldChild, in its new state (removed).
Throws:
DOMException(NOT_FOUND_ERR) - if oldChild is not a child of this node.
DOMException(NO_MODIFICATION_ALLOWED_ERR) - if this node is read-only.
See Also:
ParentNode

replaceChild

public Node replaceChild(Node newChild,
                         Node oldChild)
                  throws DOMException
Make newChild occupy the location that oldChild used to have. Note that newChild will first be removed from its previous parent, if any. Equivalent to inserting newChild before oldChild, then removing oldChild.

By default we do not have any children, ParentNode overrides this.

Specified by:
replaceChild in interface Node
Throws:
DOMException(HIERARCHY_REQUEST_ERR) - if newChild is of a type that shouldn't be a child of this node, or if newChild is one of our ancestors.
DOMException(WRONG_DOCUMENT_ERR) - if newChild has a different owner document than we do.
DOMException(NOT_FOUND_ERR) - if oldChild is not a child of this node.
DOMException(NO_MODIFICATION_ALLOWED_ERR) - if this node is read-only.
See Also:
ParentNode

getLength

public int getLength()
NodeList method: Count the immediate children of this node

By default we do not have any children, ParentNode overrides this.

Specified by:
getLength in interface NodeList
Returns:
int
See Also:
ParentNode

item

public Node item(int index)
NodeList method: Return the Nth immediate child of this node, or null if the index is out of bounds.

By default we do not have any children, ParentNode overrides this.

Specified by:
item in interface NodeList
Parameters:
Index - int
Returns:
org.w3c.dom.Node
See Also:
ParentNode

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 markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are no adjacent 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.

Note that this implementation simply calls normalize() on this Node's children. It is up to implementors or Node to override normalize() to take action.

Specified by:
normalize in interface Node

isSupported

public boolean isSupported(String feature,
                           String version)
Introduced in DOM Level 2.

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

Specified by:
isSupported in interface Node
Parameters:
feature - The package name of the feature to test. This is the same name as what can be passed to the method hasFeature on DOMImplementation.
version - This is the version number of the package name 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:
boolean Returns true if this node defines a subtree within which the specified feature is supported, false otherwise.
Since:
WD-DOM-Level-2-19990923

getNamespaceURI

public String getNamespaceURI()
Introduced in DOM Level 2.

The namespace URI of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE, this is always null and setting it has no effect.

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 created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

Specified by:
getNamespaceURI in interface Node
Since:
WD-DOM-Level-2-19990923
See Also:
AttrNSImpl, ElementNSImpl

getPrefix

public String getPrefix()
Introduced in DOM Level 2.

The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect.

For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

Specified by:
getPrefix in interface Node
Since:
WD-DOM-Level-2-19990923
See Also:
AttrNSImpl, ElementNSImpl

setPrefix

public void setPrefix(String prefix)
               throws DOMException
Introduced in DOM Level 2.

The namespace prefix of this node, or null if it is unspecified. When this node is of any type other than ELEMENT_NODE and ATTRIBUTE_NODE this is always null and setting it has no effect.

For nodes created with a DOM Level 1 method, such as createElement from the Document interface, this is null.

Note that setting this attribute 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.

Specified by:
setPrefix in interface Node
Throws:
INVALID_CHARACTER_ERR - Raised if the specified prefix contains an invalid character.
Since:
WD-DOM-Level-2-19990923
See Also:
AttrNSImpl, ElementNSImpl

getLocalName

public String getLocalName()
Introduced in DOM Level 2.

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

public boolean dispatchEvent(Event event)
Specified by:
dispatchEvent in interface EventTarget

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.

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.
See Also:
ParentNode

getReadOnly

public boolean getReadOnly()
NON-DOM: Returns true if this node is read-only. This is a shallow check.

setUserData

public void setUserData(Object data)
NON-DOM: As an alternative to subclassing the DOM, this implementation has been extended with the ability to attach an object to each node. (If you need multiple objects, you can attach a collection such as a vector or hashtable, then attach your application information to that.)

Important Note: You are responsible for removing references to your data on nodes that are no longer used. Failure to do so will prevent the nodes, your data is attached to, to be garbage collected until the whole document is.

Parameters:
data - the object to store or null to remove any existing reference

getUserData

public Object getUserData()
NON-DOM: Returns the user data associated to this node.

changed

protected void changed()
