Field Summary

Fields declared in class SectionParser

fImageBuilder, LOOKAHEAD_DEPTH

Modifier and Type	Field	Description
protected IImageBuilder	fImageBuilder
protected static final int	LOOKAHEAD_DEPTH	Depth of at least 3 is needed for J9 javacores, as parsing a section from the start will yield three tokens: SECTION, header information token, first TAG of section (note that NULL lines are ignored by the scanner).

Constructor	Description
PlatformSectionParser()

Method Summary

Modifier and Type	Method	Description
protected void	sovOnlyRules(String startingTag)	Empty hook for now.
protected void	topLevelRule()	Controls parsing for host platform (XH) section in the javacore

Methods declared in class SectionParser

addAsProperty, readIntoDTFJ

Modifier and Type	Method	Description
boolean	addAsProperty(Properties properties, String key, String value)
void	readIntoDTFJ(ILookAheadBuffer lookAheadBuffer, IImageBuilder imageBuilder)	Pass in a lookahead buffer that is shared amongst all section parsers, pass in the DTFJ factory to construct the DTFJ objects as tags are being parsed.

Methods declared in class SectionParserGrammar

anyMatched, consume, getCurrentFileLineNumber, getErrors, getLineRuleResults, getLookAheadBuffer, getSectionName, handleError, handleError, handleError, handleError, handleError, handleErrorAtLineNumber, handleRequiredMismatch, handleUnknownMismatch, isValidJavaCoreTag, isValidSectionTag, lookAhead, match, matchOptional, matchRequired, processTagLineOptional, processTagLineRequired, setLookAheadBuffer, setLookAheadBuffer, setTagManager

Modifier and Type	Method	Description
boolean	anyMatched()
protected void	consume()
int	getCurrentFileLineNumber()	Returns the current line number being parsed, or -1 if no parsing is occurring (parsing is finished, etc..).
Iterator	getErrors()
protected IAttributeValueMap	getLineRuleResults(IParserToken token)
protected ILookAheadBuffer	getLookAheadBuffer()
String	getSectionName()
protected void	handleError(Exception e)
protected void	handleError(Exception e, int behaviour)
protected void	handleError(String message)
protected void	handleError(String message, int offset, int length)
protected void	handleError(String message, Exception e)
protected void	handleErrorAtLineNumber(int fileLineNumber, String message, Exception e)
protected void	handleRequiredMismatch(String expectedType, String actualType, String actualValue)
protected void	handleUnknownMismatch(String actualType, String actualValue)
protected boolean	isValidJavaCoreTag(IParserToken token)
protected boolean	isValidSectionTag(String tag)
protected IParserToken	lookAhead(int depth)
protected boolean	match(String type, boolean required)	The match performs one additional function: if the mismatch is due to an unrecognised javacore tag, that erroneous tag can be interpreted as garbage for now, so the latter is consumed without further processing.
protected boolean	matchOptional(String type)	Match a type, but do not generate an error if mismatch occurs.
protected boolean	matchRequired(String type)	Match a type, and generate an error if a mismatch occurs.
protected IAttributeValueMap	processTagLineOptional(String tagName)
protected IAttributeValueMap	processTagLineRequired(String tagName)
protected void	setLookAheadBuffer(ILookAheadBuffer lookAheadBuffer)
protected void	setLookAheadBuffer(ILookAheadBuffer lookAheadBuffer, int depth)
protected void	setTagManager(J9TagManager tagManager)
