protected LazyEntityReference(LazyDocument ownerDoc,
                              LazyEntityReference template,
                              java.lang.String name)

Method Detail

getTemplateEntityReference

public LazyEntityReference getTemplateEntityReference()
Get the template for this node.
See Also:
LazyNode.getTemplateNode()

cloneNode

public Node cloneNode(boolean deep)
Description copied from interface: Node
Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. The duplicate node has no parent; ( parentNode returns 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 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.
Overrides:
cloneNode in class org.apache.xerces.dom.ChildAndParentNode
See Also:
Node.cloneNode(boolean)

See Also:
org.w3c.dom.Node.setNodeValue

Flag the parent as being expanded.
Specified by:
setParentExpanded in interface LazyParent
See Also:

Specified by:
areChildrenExpanded in interface LazyParent
See Also:
LazyParent.areChildrenExpanded()

setChildrenExpanded

public void setChildrenExpanded()

Flag the children as being expanded.
Specified by:
setChildrenExpanded in interface LazyParent
See Also:
LazyParent.setChildrenExpanded()

appendChildWhileExpanding

getParentNode

public Node getParentNode()
Description copied from interface: Node
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 .
Overrides:
getParentNode in class org.apache.xerces.dom.ChildNode
See Also:

getChildNodes

public NodeList getChildNodes()
Description copied from interface: Node
A NodeList that contains all children of this node. If there are no children, this is a NodeList containing no nodes. The content of the returned NodeList is "live" in the sense that, for instance, changes to the children of the node object that it was created from are immediately reflected in the nodes returned by the NodeList accessors; it is not a static snapshot of the content of the node. This is true for every NodeList , including the ones returned by the getElementsByTagName method.
Overrides:

getNextSibling

public Node getNextSibling()
Description copied from interface: Node

                         Node refChild)
                  throws DOMException
Description copied from interface: Node
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.
Overrides:
insertBefore in class org.apache.xerces.dom.ChildAndParentNode
See Also:
Node.insertBefore(org.w3c.dom.Node, org.w3c.dom.Node)

replaceChild

public Node replaceChild(Node newChild,
                         Node oldChild)

Description copied from interface: Node
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.

removeChild

public Node removeChild(Node oldChild)

appendChild

public Node appendChild(Node newChild)
                 throws DOMException
Description copied from interface: Node
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.
Overrides:
appendChild in class org.apache.xerces.dom.NodeImpl

hasChildNodes

public boolean hasChildNodes()
Description copied from interface: Node
This is a convenience method to allow easy determination of whether a node has any children.
Overrides:
hasChildNodes in class org.apache.xerces.dom.EntityReferenceImpl
See Also:
Node.hasChildNodes()

normalize

public void normalize()
Description copied from interface: Node
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 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.
Overrides:
normalize in class org.apache.xerces.dom.ChildAndParentNode
See Also:
Node.normalize()
