validatingParseDoc()

		const Definition *	ctx,
		const MemberDef *	md,
		const QCString &	input,
		bool	indexWords,
		bool	isExample,
		const QCString &	exampleName,
		bool	singleLine,
		bool	linkFromIndex,
		bool	markdownSupport )

Main entry point for the comment block parser.

Parameters

parserIntf	The parser object created via createDocParser()
fileName	File in which the documentation block is found (or the name of the example file in case isExample is TRUE).
startLine	Line at which the documentation block is found.
ctx	Class or namespace to which this block belongs.
md	Member definition to which the documentation belongs. Can be 0.
input	String representation of the documentation block.
indexWords	Indicates whether or not words should be put in the search index.
isExample	TRUE if the documentation belongs to an example.
exampleName	Base name of the example file (0 if isExample is FALSE).
singleLine	Output should be presented on a single line, so without starting a new paragraph at the end.
linkFromIndex	TRUE if the documentation is generated from an index page. In this case context is not used to determine the relative path when making a link.
markdownSupport	TRUE if the input needs to take markdown markup into account.

Returns

An object representing the abstract syntax tree. Ownership of the pointer is handed over to the caller.
