public class StreeDOMHelper

extends DOM2Helper

**For internal use only** Provides XSLTProcessor an interface to the Xerces XML parser. This liaison should be used if Xerces DOM nodes are being process as the source tree or as the result tree.

Constructor Summary

StreeDOMHelper()

Method Summary

short	getLevel(Node node1) **For internal use only** Get the depth level of this node in the tree.
java.lang.String	getUniqueID(Node node) Get the specified node's position in the document
boolean	isNamespaceNode(Node n) Tell if the given node is a namespace decl node.
boolean	isNodeAfter(Node node1, Node node2) Overload DOM2Helper#isNodeAfter, making the assumption that both nodes implement DOMOrder, and handling things if this is not the case by catching a cast exception.

Constructor Detail

StreeDOMHelper

public StreeDOMHelper()

Method Detail

getUniqueID

public java.lang.String getUniqueID(Node node)

Get the specified node's position in the document

Parameters:

node - A node in the document tree

Returns:

The position of the node in the document

Overrides:

getUniqueID in class DOMHelper

getLevel

public short getLevel(Node node1)

**For internal use only** Get the depth level of this node in the tree.

Parameters:

node1 - A node in the document tree

Returns:

The depth level of this node in the tree

Overrides:

getLevel in class DOMHelper

isNamespaceNode

public boolean isNamespaceNode(Node n)

Tell if the given node is a namespace decl node.

Parameters:

n - A node in the document tree

Returns:

true if the node is a namespace decl node

Overrides:

isNamespaceNode in class DOMHelper

isNodeAfter

public boolean isNodeAfter(Node node1,
                           Node node2)

Overload DOM2Helper#isNodeAfter, making the assumption that both nodes implement DOMOrder, and handling things if this is not the case by catching a cast exception.

Parameters:

node1 - DOM Node to perform position comparison on.

node2 - DOM Node to perform position comparison on .

Returns:

false if node2 comes before node1, otherwise return true. You can think of this as (node1.documentOrderPosition <= node2.documentOrderPosition).

Overrides:

isNodeAfter in class DOM2Helper
