parseCommentBlock()

bool CommentScanner::parseCommentBlock	(	OutlineParserInterface *	parser,
		Entry *	curEntry,
		const QCString &	comment,
		const QCString &	fileName,
		int &	lineNr,
		bool	isBrief,
		bool	isJavadocStyle,
		bool	isInbody,
		Protection &	prot,
		int &	position,
		bool &	newEntryNeeded,
		bool	markdownEnabled,
		GuardedSectionStack *	guards )

Invokes the comment block parser with the request to parse a single comment block.

Parameters

[in]	parser	The language parse that invoked this function. The comment block parse may invoke ParserInterface::parsePrototype() in order to parse the argument of a @fn command.
[in]	curEntry	The Entry to which the comment block belongs. Any information (like documentation) that is found in the comment block will be stored in this entry.
[in]	comment	A string representing the actual comment block. Note that leading *'s are already stripped from the comment block.
[in]	fileName	The name of the file in which the comment is found. Mainly used for producing warnings.
[in,out]	lineNr	The line number at which the comment block was found. When the function returns it will be set to the last line parsed.
[in]	isBrief	TRUE iff this comment block represents a brief description.
[in]	isJavadocStyle	TRUE iff this comment block is in "Javadoc" style. This means that it starts as a brief description until the end of the sentences is found and then proceeds as a detailed description.
[in]	isInbody	TRUE iff this comment block is located in the body of a function.
[in,out]	prot	The protection level in which this comment block was found. Commands in the comment block may override this.
[in,out]	position	The character position within comment where the comment block starts. Typically used in case the comment block contains multiple structural commands.
[out]	newEntryNeeded	Boolean that is TRUE if the comment block parser finds that a the comment block finishes the entry and a new one needs to be started.
[in]	markdownEnabled	Indicates if markdown specific processing should be done.
[in,out]	guards	Tracks nested conditional sections (if,ifnot,..)

Returns

TRUE if the comment requires further processing. The parameter newEntryNeeded will typically be true in this case and position will indicate the offset inside the comment string where to proceed parsing. FALSE indicates no further processing is needed.
