Class ChildNode

java.lang.Object

org.htmlunit.cyberneko.xerces.dom.NodeImpl

org.htmlunit.cyberneko.xerces.dom.ChildNode

All Implemented Interfaces:

Cloneable, EventTarget, Node, NodeList

Direct Known Subclasses:

CharacterDataImpl, ParentNode

public abstract class ChildNode
extends NodeImpl

ChildNode inherits from NodeImpl and adds the capability of being a child by having references to its previous and next siblings.

Field Detail

previousSibling_

Previous sibling.

nextSibling_

protected ChildNode nextSibling_

Next sibling.

Constructor Detail

ChildNode

protected ChildNode(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.

Parameters:

ownerDocument - the owner document

Method Detail

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. You can consider this a generic "copy constructor" for nodes.

Note: since we never have any children deep is meaningless here, ParentNode overrides this behavior.

Specified by:

cloneNode in interface Node

Overrides:

cloneNode in class NodeImpl

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.

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

Overrides:

getParentNode in class NodeImpl

getNextSibling

public Node getNextSibling()

The next child of this node's parent, or null if none The next child of this node's parent, or null if none

Specified by:

getNextSibling in interface Node

Overrides:

getNextSibling in class NodeImpl

getPreviousSibling

public Node getPreviousSibling()

The previous child of this node's parent, or null if none

Specified by:

getPreviousSibling in interface Node

Overrides:

getPreviousSibling in class NodeImpl
