Class GenerateEvent

java.lang.Object
  org.apache.xalan.trace.GenerateEvent

All Implemented Interfaces:

EventListener

public class GenerateEvent

extends Object

implements EventListener

Event generated by the XSL processor after it generates a new node in the result tree. This event responds to and is modeled on the SAX events that are sent to the formatter listener FormatterToXXX)classes.

Field Summary

static int	EVENTTYPE_CDATA Event type generated after CDATA is generated.

static int	EVENTTYPE_ENDDOCUMENT Event type generated when a document ends.
static int	EVENTTYPE_ENDELEMENT Event type generated when an element ends, after it's children have been added.
static int	EVENTTYPE_ENTITYREF Event type generate after an entity ref is created.
static int	EVENTTYPE_IGNORABLEWHITESPACE Event type generated for ignorable whitespace (I'm not sure how much this is actually called.
static int	EVENTTYPE_PI Event type generated for processing instructions.
static int	EVENTTYPE_STARTDOCUMENT Event type generated when a document begins.
static int	EVENTTYPE_STARTELEMENT Event type generated when an element begins (after the attributes have been processed but before the children have been added).
org.xml.sax.Attributes	m_atts The current attribute list.
char[]	m_characters Character data from a character or cdata event.
String	m_data The string data in the element (comments and PIs).
int	m_eventtype The type of SAX event that was generated, as enumerated in the EVENTTYPE_XXX constants below.
int	m_length The length of the current data in m_characters.
String	m_name The name of the element or PI.
TransformerImpl	m_processor The XSLT Transformer, which either directly or indirectly contains most needed information.
int	m_start The start position of the current data in m_characters.
