public class TracerEvent

extends java.lang.Object

implements java.util.EventListener

**For advanced use only** Parent class of events generated for tracing the progress of the XSL processor.

Field Summary

QName	m_mode The current mode.
TransformerImpl	m_processor The XSLT processor instance.
Node	m_sourceNode The current context node.
ElemTemplateElement	m_styleNode The node in the style tree where the event occurs.

Constructor Summary

TracerEvent(TransformerImpl processor, Node sourceNode, QName mode, ElemTemplateElement styleNode)
Create an event originating at the given node of the style tree.

Method Summary

static java.lang.String	printNode(Node n) Returns a string representation of the node.
static java.lang.String	printNodeList(NodeList l) Returns a string representation of the node list.

Constructor Detail

TracerEvent

public TracerEvent(TransformerImpl processor,
                   Node sourceNode,
                   QName mode,
                   ElemTemplateElement styleNode)

Create an event originating at the given node of the style tree.

Parameters:

processor - The XSLT TransformerFactory.

sourceNode - The current context node.

mode - The current mode.

m_styleNode - node in the style tree reference for the event. Should not be null. That is not enforced.

styleNode - The stylesheet element that is executing.

Method Detail

printNode

public static java.lang.String printNode(Node n)

Returns a string representation of the node. The string returned for elements will contain the element name and any attributes enclosed in angle brackets. The string returned for attributes will be of form, "name=value."

Parameters:

n - any DOM node. Must not be null.

Returns:

a string representation of the given node.

printNodeList

public static java.lang.String printNodeList(NodeList l)

Returns a string representation of the node list. The string will contain the list of nodes inside square braces. Elements will contain the element name and any attributes enclosed in angle brackets. Attributes will be of form, "name=value."

Parameters:

l - any DOM node list. Must not be null.

Returns:

a string representation of the given node list.
