Interface SerializerTrace

All Known Implementing Classes:

TransformerImpl

public interface SerializerTrace

This interface defines a set of integer constants that identify trace event types.

Field Summary

static int	EVENTTYPE_CDATA Event type generated after CDATA is generated.
static int	EVENTTYPE_CHARACTERS Event type generated for character data (CDATA and Ignorable Whitespace have their own events).
static int	EVENTTYPE_COMMENT Event type generated after a comment has been added.
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_OUTPUT_CHARACTERS Event type generated when characters are written to an output stream.
static int	EVENTTYPE_OUTPUT_PSEUDO_CHARACTERS Event type generated when characters might be written to an output stream, but these characters never are.
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).

Method Summary

void	fireGenerateEvent(int eventType) Fire startDocument, endDocument events.
void	fireGenerateEvent(int eventType, char[] ch, int start, int length) Fire characters, cdata events.

void	fireGenerateEvent(int eventType, java.lang.String name, org.xml.sax.Attributes atts) Fire startElement, endElement events.
void	fireGenerateEvent(int eventType, java.lang.String name, java.lang.String data) Fire processingInstruction events.
boolean	hasTraceListeners() Tell if trace listeners are present.

EVENTTYPE_ENDDOCUMENT

static final int EVENTTYPE_ENDDOCUMENT

Event type generated when a document ends.

Constant Field Values

EVENTTYPE_STARTELEMENT

static final int EVENTTYPE_STARTELEMENT

Event type generated when an element begins (after the attributes have been processed but before the children have been added).

Constant Field Values

EVENTTYPE_ENDELEMENT

static final int EVENTTYPE_ENDELEMENT

Event type generated when an element ends, after it's children have been added.

EVENTTYPE_CHARACTERS

static final int EVENTTYPE_CHARACTERS

Event type generated for character data (CDATA and Ignorable Whitespace have their own events).

EVENTTYPE_IGNORABLEWHITESPACE

static final int EVENTTYPE_IGNORABLEWHITESPACE

Event type generated for ignorable whitespace (I'm not sure how much this is actually called.

EVENTTYPE_PI

static final int EVENTTYPE_PI

Event type generated for processing instructions.

Constant Field Values

EVENTTYPE_COMMENT

static final int EVENTTYPE_COMMENT

Event type generated after a comment has been added.

See Also:

Constant Field Values

EVENTTYPE_ENTITYREF

static final int EVENTTYPE_ENTITYREF

Event type generate after an entity ref is created.

See Also:

Constant Field Values

EVENTTYPE_CDATA

static final int EVENTTYPE_CDATA

Event type generated after CDATA is generated.

See Also:

Constant Field Values

EVENTTYPE_OUTPUT_PSEUDO_CHARACTERS

static final int EVENTTYPE_OUTPUT_PSEUDO_CHARACTERS

Event type generated when characters might be written to an output stream, but these characters never are. They will ultimately be written out via EVENTTYPE_OUTPUT_CHARACTERS. This type is used as attributes are collected. Whenever the attributes change this event type is fired. At the very end however, when the attributes do not change anymore and are going to be ouput to the document the real characters will be written out using the EVENTTYPE_OUTPUT_CHARACTERS.

EVENTTYPE_OUTPUT_CHARACTERS

static final int EVENTTYPE_OUTPUT_CHARACTERS

Event type generated when characters are written to an output stream.
